Tranny SHUDDER Toyota Certified RIPOFF

My DCLB is the same , I think it is the point where the TC locks / unlocks

 

Ya as teneighty said, could be the shift point, what rpms at 40 mph? Early torque converter lock up at low rpms can result in feeling the engine through the chassis, steering and etc.

 

I would definetly check the TC. Mine was doing the exact same thing last year. At low RPMs usually right before it up-shifted I was getting shudder. Took it to Toyota and they determined my torque converter was shot. Swapped out the entire tranny assembly under warranty and problem solved!

 

Replacing the fluid is a good idea to assist in eliminating torque converter shudder making sure you use OEM fluid .
Once all the fluid and filter has been replaced , use Lubeguard as a fluid enhancer / supplement.
Professional transmission shops use Lubegaurd and the stuff works wonders .
I wouldnt waste my time typing this out if it didnt work ! it works excellent

I changed all fluid, DEALER changed all fluid, NOW they say may need radiator at my $$$, waiting on test strip determine if water in any fluid.....water in radiator not low.....I have had a loaner car for almost 14days now...WTF ??

 

I am not sure if this is any help but my wifes FJ Cruiser had a stutter as it shifted between gears. A bit of research showed there is a design flaw in the tranny (dealer says its the same tranny as the tacoma). They had to replace the tranny at a cost of $6000 (warranty paid for it). It really made me question my sanity for keeping my Taco.

 

Yes, that's my problem exactly. I have about 122k miles on a 07 TRD sport. It feels like it's shifting (shuttering) in and out of gear, especially if I'm turning slightly or going up a slight incline while holding the throttle right at the 38-40 mark. If I push or let off the throttle or down shift into 4th it goes away. Any help would be greatly appreciated!

 

For whatever reason I was under the impression that your truck was newer and less miles... Anyway... A change of fluid may help and as some of the guys said the TC. Good luck! Next service I'm going to see what the guys at the dealership say about mine.

 

I have had two instances of shudder on my Taco and both times it was U-Joints (warrantied). I knew what it was. Several friends had the same issue with their Tacos.

Tranny Fluid does not make truck shudder.

'You AND the Dealership' should know better.

 

Before everyone pinpoints the problem for the OP , what would it take to bring the truck in for a free diagnosis ?
Hooking this critter up to a scanner and going for a drive really helps in narrowing the issue down .You can even press the movie feature on the scanner when the truck begins to vibrate/shudder and go back to the shop and watch it on a computer just like real time
Diagnosing vibrations and shudders over a keyboard are impossible even though the op,s question sounds similar to the way our trucks have acted from time to time .
Universal joints cause vibrations and shudders .
Torque converter applications cause shudders in lock and unlock
There are upshifting and downshifting shudders as well
Transmission fluid can also cause shudders as it ages . There are friction modifiers in the trans fluid that break down after time and more so if the transmission hits the hot level far too many times .
There are some great answers here . Time for the OP to take it in for a free diagnostic possibly to a professional trans shop for a second opinion . A lot of trans shops will diagnose for free .

 

NOW they say it is the Bilstien 5100 shocks I installed to level the thing out....I say how come it didn't do it from day one ??? little input here would be helpfull,,,I am going after truck that has new converter and trans installed..but also has shudder........going remove shocks see what happens...............should I believe them when they say they installed trans ??? How can I check ??

 

Find another dealer...

 

I've got 200k on the original tranny fluid, and mine shudders constantly. However, since it's already a 200k transmission, and the TC likely shot, I've been waiting for the thing to grenade so I'd have an excuse to put a new transmission in it.

If it's below 10*F, I've got to let the truck warm up with the trans in neutral before it'll move. I'll put it in drive or reverse and it feels like the TC isn't building any pressure. The truck strains to move, but it won't until the fluid warms up.

I can't wait for the thing to die so I can just drop a new tranny in.

 

That's a bunch of BS... I would definetly suggest taking it to another dealer for a second opinion. I would have to argue that it IS NOT your radiator or your 5100's causing this shudder. Still not sure what kind of shudder you're getting, but I would say it's either your TC in your tranny or your u-joints in your driveshaft. If you have your truck a quick way to see if your TC is bad is to be at a dead stop in D. With your foot on the brake apply the gas just enough so your Tacoma wants to move but not enough to burn rubber. If you feel a shudder while doing this it is your torque converter.
