    THIS POST IS DEDICATED TO THE AISN WARNER A750 SERIES TRANSMISSION in your 4 liter truck.This is your 5 speed toyota automatic transmission that became available for 2005 and up Toyota Tacomas . This transmission is the only transmission behind the 4 liter engine .
    If this is not your transmission , click on my username under posts I have started and look for your transmission .

    I try to update this post at least once per week . Keep an eye on my latest edits

    Are you here because you may have a problem .
    I suggest reading through all the links below before you come to a conclusion . There is a tonne of information listed below . When it comes to transmissions , its better if you take your time and read slowly .

    Transgo finally made a kit for the A750 .
    These kits are " NOT " designed to make the transmission shift aggressive . They are designed to compensate for internal valve body wear and correct common issues due to design flaws .
    It looks like the kit may assist with the early converter clutch application that we are all complaining about . That nasty vibration at 45 :)

    CHECK YOUR TRANSMISSION FLUID LEVEL . I have seen far too many members checking the fluid level and finding out it was low directly from the factory .Toyota dealerships " do not" check the fluid on the sealed unit when they sell you the truck . With this said ,many of you have been driving with a low fluid condition for long periods of time . If you are reading this post ,you are here because now you have a problem with the transmission and it has slowly taken its time to show itself . Hopefully you catch it before too much damage is done .
    For you daily drivers in stop and go traffic ....30,000 miles and your fluid needs a pan drain .If you have overheated your fluid ...You need to flush it .This is directly from Aisn warner who built your transmission , not Toyota .
    Here is an excellent write up on how to check it http://www.tacomaworld.com/forum/2nd-gen-tacomas/63851-how-drain-refill-automatic-transmission.html

    And for heavens sakes , DONT DO THIS https://www.tacomaworld.com/threads/halp.33318/

    Page 18 of this PDF file shows how to change/check the fluid using Toyota,s guidelines

    I created a poll to see how many members are finding their fluid low directly from the factory http://www.tacomaworld.com/forum/2n...-transmission-low-fluid-directly-factory.html



    TORQUE CONVERTER CHATTER OR SHUDDER .
    A very common problem with the A750 . A combination of mechanical spool valves and electrical solenoids are used to acheive lock up . Valve body wear is very common and all we as users can do about it is keep our oil super clean
    For you guys with high mileage ......Read this http://www.sonnax.com/parts/1774
    The SLU solenoid controls your torque converter lock up and is known to cause issues if flushing your oil doesnt help . If you suspect a converter issue , replace the SLU solenoid and change " all" the transmission fluid .The SLU solenoid can also be adjusted . Turning the screw in will increase pressure and possibly fix a shudder . Do not turn it in more than 1 turn .
    Tap the brake pedal when you feel the truck vibrate . Tapping the brake will manipulate the brake switch and turn the converter lock up clutch off .keep your right foot on the gas and gently use your left foot to tap the brake . If the vibration goes away for a couple seconds , the lock up clutch or an engine missfire is your issue . This can " usually " be fixed by simply flushing your trans fluid . Some guys are getting owned because they didnt road force balance their tires using the Haweka adpater [​IMG] tsu00296.pdf
    There is also a flash available from Toyota [​IMG] T-SB-0044-14.pdf and fluid additives from Lubeguard http://www.makcotransmissionparts.com/M465HA.html to stop the shudder but you will need to figure out if you have an engine issue or torque converter issue.
    Lubeguard is well know in the transmission industry and works amazing for fixing converter shudders . You can see the product lower down in the threads .I would not post about Lubeguard if it didnt work . This post is designed to save you money , not waste it replacing your torque converter . Find some Lubeguard and "USE IT"
    In the illustration below , its going to show you how to pick out a missfire .That vibration you are trying to pinpoint at a certain speed can be dublicated in your driveway if the issue is engine related .. To diagnose this , use the chart below

    SHOULD YOU USE THE PARKING BRAKE WITH AN AUTOMATIC
    I use the ebrake every day and I have an automatic transmission. Using the ebrake when parking is recommended in the Toyota manual . Living way up North in the snow as I type this , they use all kinds of salt .Its better to use the ebrake than have it seize up solid and pay $500 bucks to have all the cables replaced when its time to sell the truck.
    With this said , using the ebrake keeps the rear brake shoes adjusted properly and saves your front brakes from wearing quickly
    You're also being very nice to the parking pawl inside your transmission. Lots of people just jam it into park on an incline and don't ever use the e-brake. Or worse, jam it into park when the vehicle is still rolling. An e-brake cable is a cheap fix compared to a transmission problem.
    There was mention of using the emergency brakes with auto and manual transmissions and I totally agree .
    Use them every time you park
    Its one of the best things you can do to keep your truck rolling to a stop smoothly and parking smoothly for many miles to come .
    1 - Keeps your rear brakes adjusted properly so when you need to come to a stop quickly you are using all 4 brakes rather than just the two up front
    2- When coming to a stop and preparing to park , hit the ebrake which unloads the energy or weight of the truck off of the transmission parking pawl .
    Your brakes are going to last longer and you are going to produce less metal to metal wear inside the transmission.
    Here is a pic of your parking pawl . That tiny gear and locking assembly with that tiny steel pin are assigned the task of holding your 4000 pound truck from rolling . Add some bigger tires and a heavy bumper and you are asking for grief .
    I have replaced many of these .
    Look what happens when you dont use the E brake http://www.tacomaworld.com/forum/2nd...ml#post9531711


    FLUSHING YOUR TRANSMISSION
    I have serviced approx 4000 automatic transmissions . Does this make me a pro with the A750 series transmission in your Tacoma? NO , but I will try and explain
    Years ago , most of the shifting was controlled by hydraulics or mechanical spool valves inside the valve body . When a customer brought their transmission into my transmission shop to have it flushed ( without removing the pan and filter ) there was a possibility of forcing the material from the bottom of the transmission pan into the valve body causing the spool valves to stick .This was very common with the popular GM 700R4 and Chrysler A670
    As transmissions get newer , electrical solenoids and sensors are taking place of the many mechanical spool valves in the valve body . Solenoids now have a larger bore. In saying this , flushing a transmission can now be performed with less possibilities of hydraulic spool valves getting all gummed up and stuck.
    If you plan to flush , get quotations from a shop that uses a flushing machine with the pan and filter removed .They are the best flushing machine to use because this machine guarantees the pan was removed before the flush was performed .
    This method attaches the machine’s line out to the pump intake. The process transfers fluid through the vehicle and into a drainage pan, completely flushing the system. When cleared, new fluid is supplied to fill up the car. This process requires the complete removal of your pan and filter and a new filter and pan are installed at the end. This requires more time, a few extra quarts of fluid (around 20) and costs a bit more, but it is a much more complete, ideal procedure. - See more at: http://www.transmissionrepaircostguide.com/what-is-a-transmission-flush/#sthash.YDlT9xaq.dpuf
    Once the pan and filter have been removed , connect the flushing machine to the filter suction line in the valve body casting , start the vehicle and flush away .
    Dont go to a shop that uses a cooling line flushing machine WITHOUT MAKING SURE THE PAN IS REMOVED FIRST .The guy telling you to flush without removing the pan first must have ESP ? How does he/she know the condition of your transmission . Remove the pan first regardless of miles.
    All Flushing machines use your transmission pump to mix/force the old oil out and your engine has to be running to turn the transmission pump .Flushing machines will Never flush fluid backwards through a transmission or what some quick lube shops call reverse flushing / backflushing . Your transmission pump only turns one way so dont let those guys fool you into thinking they have a special super flushing machine .
    Note: Some service centers use machines that add additional force to blast fluid and/or cleaning solution through the system. This is NEVER a good idea as this can damage seals and/or lodge sludge in places it shouldn’t be as mentioned above. - See more at: http://www.transmissionrepaircostguide.com/what-is-a-transmission-flush/#sthash.B2SaFB52.dpuf
    If the truck was mine or a customer of mine , I would get that old stuff outta there .
    There are 11 duties transmission fluid carries out inside the transmission .New fluid will help to prevent transmission failure .
    1 - transmission fluid is the lifeblood of your transmission.
    2- Trans fluid lubricates every part inside the transmission ...at minumum 1000 moving parts which is far more than what your engine has
    3- Trans fluid is used to keep your transmission cool
    4- Trans fluid is used to transfer hydraulic power
    5- Trans fluid is used as a coupling device to transfer engine load to the gearing .
    6- Trans fluid acts like a glue when automatic clutches are applied providing additional holding strength.
    7- There are more , dont remember the rest hehehe

    should you use a fancy in line magnetic filter ?
    I would not chance placing a filter in line of "cooler flow" .Its the wrong place to install a metal cleaner .Cooler flow is extremely important and We all know heat kills an automatic transmission . You are not going to know the filter is plugged until the trans temp light pegs out at 310 degrees . You are too late by then and have cooked your trans fluid unless you have a trans temp guage that you monitor on a constant basis .
    Did I use them in my transmission shop ? absolutely but only for a two week duration as described in the quote .
    The filter in the pan is designed to catch large particulates including metal . Magnets laying in the bottom of your transmission pan accumulate metal over time but there are small particles of steel that the Toyota pan filters allow to pass through . If you install a magnetic in line filter in line with " cooler flow ", sooner or later chunks of metal will accumulate on that magnetic in line filter and restrict the flow .Pop your transmission pan off and clean the magnets , clean the mesh filter and keep your fluid as clean as possible on a regular basis and you will be fine .
    For the non believers in the group , call around to a few transmission shops and inquire about the Magnetic in line filter but please talk with a journeyman .
    If you have one on your truck , remove it and cut it open to see whats inside .

    ENGINE BREAKING and harsh downshifting .
    For you guys with higher mileage ....Read this http://www.sonnax.com/parts/1778
    Page 33 and 34 of this PDF explains downshifting
    http://www.toyotatundraforum.com/pdf/A750E.pdf
    Are you effected by the TSB ? http://www.pdf-archive.com/2012/01/06/tsb-0373-09/tsb-0373-09.pdf
    beleive it or not , your truck is designed to save fuel when coasting . When you take your foot off the gas , the PCM tells the injectors to turn off . This is why your truck feels like its slowing down in comparison to older vehicles you have owned . Combine this with the converter remaining locked up and the transmission downshifting while going down hills can really be felt in the drivers seat .

    I have overhauled many Aisn Warner automatic transmissions . For the most part , a good reliable transmission producer . I beleive all domestic and import manufacturers now use this company for transmission applications . Each transmission design has its own bunch of common headaches/ design flaws . Some of these headaches or design flaws are engineered into the transmission and some are simply poor design .In our case the A750E has torque converter shudder issues or so they say . Overall , the A750E has a good track record other than this dreaded shudder that some of you experience .
    Proper diagnosis is the key .
    First things first . Change your fluid
    I see a lot of posts at TW where the OP had his torque converter replaced and the issue was resolved , Who manufacturers the torque converter for Aisn Warner ? anyone know ? what compounds are they using on their lock up friction disc ?
    Are they applying the converter too early , too late ? partial apply ?
    Lock up torque converters have been around for half a century and the function they play within the transmission/drivetrain is designed to save you a lot of fuel .
    This new fancy WS transmission fluid as it ages with heat may have something to do with the shudder .
    There are more than one Tacoma transmission problem that results in a quote "Vibration or shudder "ANY" transmission problem is called a shudder and dumped into the same pot.

    When the ws fluid starts breaking down several things can happen. One problem is the converter clutch disc can glaze up and start causing vibes and shudders . Another problem is the pressure control solenoids can hang up and cause a shift shudder problem. Another problem is the Torque converter regulator valves can wear in their alluminum valve body bores and cause shuddering.

    Another issue is really not a transmission problem at all but feels exactly like a torque converter shudder. Engine misfire conditions from a faulty spark plug, weak coil or dirty injector . The missfire goes un-noticed until the torque converter locks up. Using a scanner ,watch the down stream O2 sensor and the short term fuel trim . Pay close attention to the monitors in using mode six on the scanner can give an indication of a misfire. If the miss-fire is bad enough, your check engine light will illuminate .

    If you develop a shudder the first thing to do is change your fluid. This alone is usually enough to fix the problem if it's glazed friction material. If the shudder still persists try the Lubegard product next. http://www.lubegard.com/~/C-230/Dr.+Tranny+Instant+Shudder+Fixx

    I beleive half of the warranty torque converters you guys had replaced were " NOT " actually converter issues but a direct condition of the WS transmission fluid breaking down .

    Try changing your transmission fluid first . Cleaning the throttle body and mass air flow sensor have claimed to fix up some funky shifts and dont forget while you are there to clean Idle Air Control valve as well
    here is a good link that shows you how to clean these http://www.tacomaworld.com/forum/technical-chat/94203-how-throttle-body-cleaning-2005-v6.html


    Here are some good mods
    2ND GEN TIPS AND MODS http://www.tacomaworld.com/forum/2nd-gen-tacomas/7174-2nd-gen-tips-mods-more.html


    Shifter stuck in park http://www.tacomaworld.com/forum/2nd...-failed-2.html


    USE your emergency brake while parking on hills or slight inclines . Its going to make things easier to come out of park when you try and start your truck when you get back in the truck . Sometimes you have to manipulate the steering wheel by hand to get the key to turn

    STICKY SHIFTER / SHIFTER IS HARD TO MOVE
    Most of us would disconnect the shifter cable from the transmission lever and then verify the cable is free by hopping in the truck and moving the shifter from park to low . We should feel nothing because the shifter cable is no longer connected to the transmission . If the shifter is still tight to move , we know that the issue resides in the cable or the plastic shifter cover . A quick lube job is going to fix that up .

    Next , with the shifter cable removed from the transmission lever , try and manually move that transmission lever by hand . You should feel click , click , click and it should be fairly easy to move with your hands . If you cant move it by hand , remove the PRNDL switch shown on page 16 at this link , it shows the switch in question . Spray the heck out of it . Some guys actually have to replace the PRNDL switch becuase of corrosion .The PRNDL switch gets very tight when it corrodes http://www.toyotatundraforum.com/pdf/A750E.pdf

    When the switch is removed , you can spray the seal on the transmission that sits behind the switch to see if there are additional problems with the lever shaft since the lever shaft is also known to corrode .
    , then take a small screwdriver and pry the lever seal away from the shifter selector shaft enough to blast some lubricant between the seal until you get the lever to move by hand .Might have to work it back and forth a little but its going to free up . You should have the wheels blocked when you do this .Both of these issues are very common

    Next , place the transmission gear shifter in park and " REMOVE THE KEY "
    Throw the key on the drivers seat until your done .
    Go to rear of truck and manually push it by hand to verify the truck is actually in park . Go back under the truck and check to see if the shifter cable lines up perfectly with the hole in the transmission lever . If it doesnt line up , adjust the shifter cable until it fits perfectly into the transmission lever . The adjustment is under the shift counsole .
    Once the cable is aligned with the transmission shift lever , verify the truck will only start in park and nuetral .

    P0705
    This covers any normal shifter cable and alignment issues and all diagnostics start on page 53 of this pdf http://fjcruiser-club.com/docs/RM/A7...0Transaxle.pdf

    Then read here http://www.tacomaworld.com/forum/2nd-gen-tacomas/311737-p0705-code-popped-yesterday.htm
    .
    and here https://www.tacomaworld.com/threads/solved-need-help-fast-truck-will-not-shift-out-of-park.390784/

    Now you know the shifter is free with the truck in the off position .
    Now , start the truck and verify you can smoothly shift through all the gears . Has the shifter freed up or is it still really tight ?

    If its still tight with the engine running , remove all ground straps and clean them spotless . Add additional ground straps if you please .
    I have seen vehicles catch on fire for this very reason .
    When the ground wires on circuits get old and corroded , they no longer function properly and loose contact with ground . Guess what your shifter cable just became ? The ground wire from your transmission to the vehicle body .
    I have replaced many melted shifter cables . The shifter cable becomes the vehicles ground and the plastic outer shield will actually melt to the inner cable . This is more noticeable on todays vehichles with all the fancy control motors and electronics as they draw much more amperage in comparison to older cars and trucks . With the non metal box on our trucks all we have is the frame and truck cab to rely on for our grounding needs .
    A little sand paper used to clean those ground straps usually fixes the problem but you can always add a couple more straps to be safe . Some guys are too late and the cable is fried . Some guys replace the cable without replacing or cleaning the grounds only to have the same issue again .
    Let me know if this helped [​IMG]

    Spoon , Can you back up your statement ? You have to give the members here at TW some insight .[​IMG]


    As mentioned in the original post . These are called shift kits because of the manufacturer . The company has been at it for years and years . In a way , i guess they are a shift kit because they change the original shift strategy designed by Aisn Warner and improve on it .
    If you want protection from design flaws in a daily driver , install one of these kits.
    I have used the company for years and the recalibration kits do exactly what they say .



    If you want a race transmission , install a high stall converter and an IPT performance valve body

    Drop the valve body and block off the accumulators - very easy to do . The shift will knock your head into the rear window lol . Making a transmission shift hard is actually better for the clutching inside an automatic but can be hard on planetaries and other hard parts within the trans .

    When Aisn Warner designed the transmission , they think about all the grandpa,s out there that want a nice smooth shift :D

    Hypertech speedometer calibrator http://www.hypertech-inc.com/products-speedometer-calibrator.aspx

    Lets look at some Vibration diagnostics . Anytime someone asks a vibration question , I copy and paste this .
    I believe there are at minimum at least 12 different vibration issues assosiated with the Tacoma and all the vibrations / shudders get mixed into the same pot leaving members scratching their heads .
    Have you greased your driveline ?http://www.tacomaworld.com/forum/tec...rks-total.html
    Do you know how to grease your driveline properly http://aftermarket.federalmogul.com/...%20FAQ%27s.pdf
    Have you checked your carrier bearing https://www.tacomaworld.com/threads/how-to-replacing-carrier-bearing.260283/
    Does the truck vibrate in park or neutral and does the vibration change with accelerator pedal ? This is a misfire test for your engine
    Does the truck vibrate while holding the brakes and hitting the gas - Automatic ? This is also a misfire test for your engine under load
    Does the truck vibrate in neutral at a stand still ?or coasting in neutral ?
    Does the truck vibrate in 4x4 ?
    Does the truck " Only vibrate " from 1st to 2nd gear ? https://www.tacomaworld.com/threads/vibration-when-accelerating-from-stop-anyone-fixed-it.300155/
    Does the truck only vibrate in 2 wheel drive ?https://www.tacomaworld.com/threads...differential-bearing-vibration-thread.152173/
    Does the truck vibrate with the serpentine belt removed ?
    Does the truck vibrate cold or hot ?
    Does the truck vibrate if you select neutral and coast to a slow roll without using the brakes ? What happens when you turn the truck of in Neutral at highway speed ? Can you still feel the vibration ?
    Does the truck vibrate as you are braking ? When was your last brake job ? Consider the front rotors may be warped or the rear drums are out of round .
    Does the truck vibrate with weight in the truck or empty ?
    Does the truck vibrate while upshifting ? Have you checked your trans fluid ?
    Does the truck vibrate while downshifting ? Have you checked your trans fluid ?
    When was your last transmission fluid service ?
    Is the vibration caused by your torque converter ? Tapping the brake pedal at highway speeds will release the torque converter clutch . You are not actually hitting the brakes ,but manipulating the brake switch . If the vibration goes away you can expect a misfire or a converter clutch issue .
    Read here for more information regarding automatic transmission diagnostics
    https://www.tacomaworld.com/threads...th-pics-for-second-gen-4-liter-trucks.289913/
    Now that you have a lift kit installed the truck vibrates . Did you cancel your drive line angles ?
    Have you looked at the condition of your tires ? Toyota says to rotate every 5000 miles .Tacoma tires must be road forced balanced using the Haweka adapter on the tire machine [​IMG] tsu00296.pdf
    When was the last time you rotated your tires ? Are you using LUG centric aftermarket wheels ? have you considered " HUB centric rings " http://www.amazon.ca/s/?ie=UTF8&key...vptwo=&hvqmt=e&hvdev=c&ref=pd_sl_7ybe1f1pby_e
    Have the balance weights fallen off the tires ?
    A good vibration technician can tell immediately if your vibration is caused by the rotating speed of your wheels or by the rotating speed of your driveshaft .
    If you go through this list carefully , you should be able to narrow down where the problem is .
    The proper and only way to test for bad universal joints is with the driveshaft removed . You cant tell if the universal joints are seized or tight spots with the driveshaft on the truck . You may see play in the universal joints , but you wont be able to properly check the u-joints without removing the driveshaft .All it takes to create a vibration is one seized universal cup and there are 4 cups within each joint .
    With this said , you cant tell if that cup is seized with the driveshaft connected .
    Removing the driveshaft and manipulate each universal joint by hand from side to side feeling for tight spots as you go is the only way to check for bad u joints
    If you beleive its bad motor mounts or transmission mounts , grab a big pry bar and pry at the mounts to see if the rubber is torn or weak .

    well damn! haha i know on my dad's silverado when he had his transmission flushed they turned up the line pressure so it would shift harder and it definitely does

    Yes it does . 1/4 turn with a #8 torx driver . nice solid shift !! :)

    Lets have a peek at what transmission coolers do
    TRANSMISSION COOLERS
    If you do not have a transmission cooler on your truck and you plan to tow or haul heavy loads or you are in heavy stop and go traffic and use 4X4 low a lot , consider purchasing a cooler . The cooler thats built into your rad is designed to cool the transmission with the weight of just the truck by itself .When you are in 4x4 low , your torque converter is usually in the stall stage and creates a tonne of additional heat .You dont have much air flow going through your rad when you are in low range 4x4 .
    160 - 200 are considered normal temps providing your engine radiator is functioning properly . If your engine overheats , your transmission will also overheat
    Normal fluid temperature in transmission to be 175 deg. F.

    Rate of oxidation to double for each temperature increase of 20 deg F above normal (175 deg F). As oxidation rate doubles, useful life of fluid is cut in half.

    At 175 deg F life is 100,000 miles
    At 195 deg F (20 deg above 175) life is 50k miles
    At 215 life is 25k miles
    At 235 life is 12k
    At 255 life is 6,250
    At 275 life is 3,000
    At 295 life is 1500
    At 315 life is 750

    At temperatures much above 300 deg F the metals in the transmission will tend to warp, twist etc. high temperatures causes the formation of varnish deposits which impair or pre vent transmission operation.

    At a fluid temperature of 415 deg F fluid life is 30 minutes!

    Consider a scan guage [​IMG][​IMG]http://www.amazon.com/ScanGauge-Comp.../dp/B000AAMY86
    Here is the best information for the scan guage http://www.tacomaworld.com/forum/2nd...-pressure.html

    Ultraguage is now offering transmission temps http://www.tacomaworld.com/forum/2nd-gen-tacomas/318340-ultragauge-transmission-temp.html

    You could also use the Torque app with an Android phone as a cheap alternative to watch your temps http://www.tacomaworld.com/forum/per...d2-reader.html

    This is how Low Pressure Drop technology works::
    When Automatic Transmission Fluid (ATF) is cold it is viscous. The unique Tru-Cool design allows the colder, thicker ATF to flow more efficiently through two open bypass channels positioned at the top of the cooler. As operating temperatures increase, the ATF becomes hotter and thinner, It's then directed through the core where it is cooled. Tru-Cool's highly efficient cooling technology combines improved protection against lube failure with optimal heat transfer.
    [​IMG][​IMG]http://www.amazon.com/Long-Tru-Cool-.../dp/B005XZXB1M
    Long Tru-Cool Oil Coolers offer advanced cooling protection for many towing applications. The advanced technology out performs TUBE & FIN Designs, Delivers up to 15 times less flow restrictions, 30% more cooling delivers maximum heat transfer, Self-Regulating for maximum lube flow protection through start-up, varied temperatures and driving conditions, heavy loads and towing.
    Here is Toyotas fluid flow guide ...Look at page 8 on this PDF http://www.toyotatundraforum.com/pdf/A750E.pdf
    And here is a guy who recently installed a cooler correctly http://www.tacomaworld.com/forum/1st...agram-pic.html

    According to Lubegaurd , they have 2 products that are compatible with that poorly designed WS fluid . WS fluid turns black very quickly . In my mind , its the largest cause of many transmissions concerns with the Tacoma . The A750 uses the same friction clutches that they used in the early 1990,s . I prefer Mobil 1 or Amsoil . Red Line synthetic is good as well .
    The Dr tranny shudder fix and the friction modifier .
    This stuff works wonders . Ask any transmission repair shop . Even used with OEM transmissions and dealerships

    I remember the slick 50 . Dont recall if it worked or not . You wont see Lubeguard on any telelvision commercials . You wont see it in Wally world either . You will see it stocked in transmission shops and in the back of dealerships becuase it does what it says . This product works like it states

    Here is the TSB for a sticky prndl switch
