    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 .
    I will always point at the " True Cool" company for their fantastic line of transmission coolers . They are the original designers of Low Pressure Drop Technoligy and for this reason , many factory coolers are made by this company . I have used these guys for years and years . The hardware and quality hose that come with the 4454 work perfect for our Tacoma,s . I do not suggest using the zip tie through the rad installation .Thats just asking for trouble as I have seen radiators leak where the zip ties are holding the cooler in place . If you ever need to service your radiator , the radiator techs will be happy they dont have to mess with a transmission cooler stuck to the rad .
    Take the extra time to bolt the cooler in place using the metal brackets that are supplied in the kit .
    Check out their website for more info
    You cant overcool with these coolers which allows you to go overkill , but keep in mind ,a large transmission cooler will block off air flow to your rad .
    I use a 4454 on light trucks and 4490 on full size
    http://trucool.com/

    Whats wrong with other coolers ?
    Do they offer winter protection ? I suggest looking into this before you purchase
    If they do offer winter protection and you are getting a great deal ...Grab the cooler . If winter protection isnt an issue , grab whatever cooler you want as long as the specs dont list any restrictions to fluid flow

    Got any questions ? send me a pm !!
    Here is a 4454 as an example https://www.amazon.com/dp/B005XZXB1M
    Here is an example of the 4490 https://www.amazon.com/Long-Tru-Coo...785&sr=1-1&keywords=transmission+cooler++4490

    For the members with the tow package , you do have the option of removing the tiny factory aftercooler and installing a larger cooler in its place making this the best placement for an aftermarket cooler . There is no need for 2 aftercoolers if you can do the job with one aftercooler . Removing the factory aftercooler eliminates a bunch of extra fittings and hoses and lowers the leak factor if you were to leave it in place and add a second cooler .https://www.customtacos.com/tech.ol...6toyrm/06toypdf/06rmsrc/rm2006ta/02800810.pdf


    Look at the True Cool web site GVW ratings for the cooler that makes most sense for what you plan to do with your truck

    Are you planning to use 4x4 low often in warm areas of the world ?
    This is probably your best bet !!!! There is no air flow through your rad while crawling
    cooler and fan install http://www.tacomaworld.com/forum/2nd...n-install.html



    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 to keep an eye on your transmission temps [​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

    Installing a new radiator or you need to make sure your cooler is clean ?
    Use this product [​IMG]$7 Lubegard 19001 Dr. Tranny Kooler Kleen Trasmission Line Flush, 13.25 oz.https://www.amazon.com/dp/B001DKNH8I?aaxitk=MYxoLs5I4LwRQxZC0Y9EDw

    And here is a guy who recently installed a cooler correctly http://www.tacomaworld.com/forum/1st...agram-pic.html



    HERE is the Tacoma World Towing Bible https://www.tacomaworld.com/threads/the-tacoma-towing-bible.4031/

    CAN YOU OVER COOL ? Yes . Transmissions are designed to operate at 170ish . There are demulsifiers in the fluid to assist with internal condensation but you still need the steady heat to bake that water off . If installing a cooler , ask yourself what plans you have for the cooler during the winter months .
    Where you live makes a crucial impact on transmission cooling

    When you first start your truck in the morning , the transmission uses the heat provided by the engine to warm the transmission .
    This results in better fuel economy as well as improved transmission shifting .
    With this said , I will always recommend using the factory in line radiator and then place the cooler after the original rad .
    There are exceptions to this rule mind you . The strawberry Milkshake effect , a former transmission failure causing the internal rad cooler to plug up or you simply live in an extremely warm area

    towing a light trailer with a vehicle not designed for towing, even an empty trailer causes the TCC to stay unlocked when driving on a slight incline. I have seen this happen more than once. The converter turns blue and the fluid turns clear. The customer brings the car in because the check trans light is on. $$$$$

    I have had a B&M racing oil cooler installed on the truck for a long time now. It runs in series with the factory cooler. So Trans, Factory Cooler, B&M cooler, trans, and so on. Keeps things nice and cool...

    It's just a good idea in general. Better to have and not need than need and not have.

    I'm worried about keeping it cool with the setup I have planned.. I talked to a guy with my dream engine setup, he said he's around 400hp. I want to do that and have 37s.. Regeared with 5.29 gears

    Are you watching your transmission temps ?
    Maybe a scan guage or Ultra guage to start ?
    https://www.amazon.ca/ScanGauge-Aut...F8&qid=1515992662&sr=8-1&keywords=ultra+guage

    Compare the difference from the smaller wheels to the larger tires
    I beleive you will find out quickly that adding an additional cooler will help

    Right now I'm 33s, stock gears, stock engine. going to install the gauge with 37s and gears to see where it's at, then Afterwards I'll add the cooler to see if it makes a difference

    Will post results once it's done

    I heard the tow package already has a small one, is that right? And if so should it be upgraded or should I have 2?

    I finally got my trans temp gauge installed. On hot days, I’m seeing average temps in the city around 160-165. In a lot of stop and go in hot weather, I’ve seen it go to 175, but once moving again it dropped back to 165 very quickly. In this cold weather, I’m seeing top temps of 150-160. This is with the radiator cooler and an auxiliary cooler.

    Any recommendation on specific Tranny coolers? I'm going to be adding one soon and was curious what's being used out there. My truck does not have the factory tow package. I already installed the hitch, wiring and brake controller is coming along with the tranny cooler. We'll be towing a tent trailer in the 3k-4k range.

    B&M Racing makes a very stout cooler. Got mine from Summit Racing.
