I've noticed lately that when the car is still cold, the transmission has a tendency to randomly downshift. This is usually within the first 30 seconds of driving the car, and it will happen even if I only give it maybe 1/8 throttle. I've also taken notice that it happens right after I make a turn. It will only do it once, too...never more than once until I turn the car off and let it get cold again.

Only reason it really worries me is because when it downshifts, the RPMs will wind up to about 4000, which is a big no-no for a cold engine.

Anyone have a clue?

 

No thoughts?

 

I dont know much about the auto trannies but maybe a selenoid?

it only happens withing the first few mins of driving?

 

Just make sure it doesn't happen while passing a Cobra or he'll think you wanna race.

 

Yessir.
Good thinking!

 

No other thoughts?

 

Ive had that happen a few times too....its weird...you dont expect it to happen and all of sudden theres a hard downshift.

 

Yup...mine did it today after school and revved to almost 4500

 

Our auto trannys are notorious for staying up in 2nd or even 3rd gear during a rolling stop when they are cold. Applying some throttle to take off causes it to downshift, sometimes jumping down into 1st gear and sending the RPM's way up.

It's pretty normal, just be gentle on it for the first few minutes of driving. As it warms up the downshifting will become a bit better.

 

my old auto did that too....just take it easy in her until it warms up....like said before it could be the solenoids going bad....i cant remember if mine did that before or after i replaced the tranny
