My truck shakes when changing gears

X2
The link posted will not replace all the transmission fluid BTW. You should replace your transmission fluid every 60k miles.

 

I don't know if I would use the phrase "My Tranny" there

 

Take it back in or have a second opinion from another mechanic..............

 

Here is an update:

After having a full flush and sending off a sample of the prior fluid off to Blackstone there is no change. The Blackstone analysis reported nothing out of the sort. The current status is that my truck still shakes.

I'm at a loss.

 

Might be the torque converter after all...

 

Slippery- I am having the exact same problems with my 2006 tacoma. It just started about 2 months ago. Have you found a solution to the problem yet?

 

I haven't found, nor have I sought a solution to the actual problem. I found that when I take my truck out of overdrive and allow the gears to shift automatically until I'm in 3rd I don't have the shimmy. This has been my practice for a while now and it seems to work well.

Not optimal, but I'm not spending several grand to replace a transmission when I'm pretty sure the issue isn't mechanical.

 

I wouldn't necessarily say your mechanic did anything wrong but these thransmissions are a lot different than other transmissions. When I went to have my transmission flushed I called 4 different places and no one would touch it other than the Toyota Dealership. When you had it flushed for he second time, was this done at a Toyota Dealership?

 

Thanks for the feedback slippery. I took mine to a transmission guy in my town that has been doing it for 40 years and he couldn't figure it out but didn't think it was the transmission, idk. He told me to drive it until it got unbearable or a light came on then he could hook it up to the computer and see if it hit on anything. It's just strange that our trucks are doing the exact same thing. Mine too is a 2006 double cab v 6 automatic. I noticed mine does it worse if I am easing up a slight incline but I can give it a little gas and it chages just a smooth as the day i got it

 

My 2009 just recently started doing the shifting shudder when in OD. Does not do it all the time and seems to do it more after it has warmed up a bit. I tried taking it out of OD until I'm up to highway speeds, say 50 and then going to OD. It does not shudder on shifts like this. I'm fearing something in the transmission or torque converter

 

Any updates? My truck does the same thing.

 

Yes, I called up my local trusted mechanic to see what he knew about this problem. He was familiar with the issue. He told me he could flush the tranny, replace the filter, Toyota Fluid, add a friction additive and he had a 50/50 success rate with this. He said total cost would be $400.

I had just received word from the Toyota dealership that a new tranny was required at over $2500. I elected to try the $400 flush.

I would say it is 95% as good as it was the day I bought it. Shifts really well. When I originally decided I had a problem and took it to Toyota, (my dealership throws in a lifetime drivetrain warranty with the purchase), I'm almost certain they also reloaded the shifting software during their diagnosis. Before, the truck would downshift at odd spots when going through turns and up and down hills. I understand there were some issues with the engine break logic. That's gone as well.

Anyway, I have about 130,000 on my 09. Serviced tranny at just over 125,000 and I'm not seeing the issue anymore. Toyota absolutely knows they have a problem with this, but I don't think they want to acknowledge it. I went back to the dealership and told them I wanted to get this on record with them due to the lifetime drivetrain warranty. Met with the Service Dept manager and the salesman I bought the truck from. Laid it all out there that I brought it to them for help and they offered a $2500 solution. Took it to an independent 3rd party garage and for $400, got it fixed. The service manager said $400 was too high for a service. I asked him why he didn't offer it if they could do it cheaper. He took the company line and said Toyota recommends replacement. They know they have a problem. They just want the consumer to pay for a solution! Good Luck!!

 

In this forum, how many individuals have this same problem? I am writing a letter to Toyota and would like to document more than just my problem. If you'll send me your username I'll be happy to include you as those with similar complaints.

 

Maybe I'm to late, But I just joined here because I was looking for an answer to this EXACT problem. If I take it out of O drive it's ok. Then when I get up to speed I shit it back into O drive. OR if I punch it, it doesn't do it either. Mostly when driving slow in town. And after seeing others with the EXACT same problem then something is not right. What is it?
It sure gets on my nerves though. I have not taken it in to be worked on yet.

 

I see a lot of guys have this issue but no one is admitting to the neglect they gave the trucks. "It's Toyotas fault" etc. Most problems in my life arose from something I did?
Now, don't jump all over me on that statement as I know there is a flip side to the coin and that some of you poor guys had this issue from the start with very little mileage on the trucks. That sucks for sure but Toyota should buck up, if it's under warranty and change your torque convertor. -I am not just saying that, this is what Toyota did to a friends truck and problem solved.

With that being said, another one bites the dust. Just hit 110,000 mi on my 10 trd offroad. I have a shudder/slipping/shake on a light acceleration. The shake comes a few seconds before it changes gears 2nd to 3 and so on. Like everyone else, it goes away in when I take it out of overdrive or accelerate more aggressively through the gears.

It feels sort of like the take off shudder but a little longer frequency in between the shudder.

Now for the part I pin the problem on me rather then the Toyota.
In hindsight, I suppose all the fishtails and burnouts in the snow hasn't helped. The problem reared its head yesterday when I put the hammer down to beat a red light camera. The intersection had a big hump in it and I caught a little air. Also, both rear icons 2.5's are blown from whoop D doos at 70 down the beach. The only way to do 70 is in 2 wheel and on soft sugar sand the wheels are spinning and gripping the entire 7 miles I drive the beach. The blown shocks probably doesn't help either. Moreover, I never did a tranny flush as recommended. So all in all, this is my fault!

So what's the issue? It's your torque converter! Probably around $2800 from the Stealership! What's the alternative? As said earlier, drive in D4 and switch to overdrive after 50 for the rest of the trucks life or flush the fluid and cross your fingers then sell your truck.
Good luck 00

Good read and write ups. I still can't believe some of the write ups on this site.
There is definitely a good possibility the level is low. Quick question, you mentioned that sometimes they are low from factory from the get go. Besides an apparent leak, how else can you loose the fluid? Can an overheat or such cause a loss of fluid. I have 110k on my truck and never had any unordinary issues except, now that I think about it, about a month ago I smelt tranny fluid-Ha I checked for leaks but it was nearly impossible because everything was wet and snow covered. I never smelt it again and never saw any leaks after that. I chalked it up to a blown tranny in the plow trucks around town.
Luckily I have some "in's" at the dealer so I won't be raped and lied to when they do the flush. For now, I am going to pay for the flush. Thanks for the read/edu.

There is no other way the fluid can leak out unless you have a leak and the flash point is very high ( 450 )so you are going to smell it if you beleive the fluid is burning up .

Dealerships dont touch the valve body when specific problems with shifting show up . They might drop the pan to change a solenoid but I beleive thats as far as they go .I doubt they have a pressure guage to properly test our transmission as per Aisn Warners guidleines
They simply quote you the cost of installing a new transmission hoping you bite without properly diagnosing the problem .

 

I am quite familiar with burning tranny fluid. My dodge 1500 lit on fire when the spark plug guard rusted off, dropped down and arc'd from my starter to the fluid line then spit onto the exhaust. poof! Starbucks cappuccino and a gatorade put it out. I don't recommend throwing water on oil fires but that's all i had and it worked after a big flash of flames.

I thought you would say that there was no other way to loose fluid. i am not going to replace the tranny/torque converter. I am just going to get the flush cross my fingers. I doubt that I will let them know that I am having issues shifting.

 

Just a follow up on the shaking when changing gears. Dropped off the truck to Toyota Saturday morning for Tranny Fluid Flush. They said they had a flush machine. I didn't get to speak with the mechanic afterwards but the invoice said they used a tranny service kit. I am not sure what they really changed besides the fluid but I no longer have the shake/shudder when switching gears. Final cost after some discounts $253.00 with tax. I guess it helps to know someone as customer service was nice, service fast and cost was less then expected. They somehow fixed my tire pressure sensor so the light no longer comes on. Thought it was busted as I had evened out the pressure and light stayed on. Anyway thanks for the info.
