My 2001 will shift smooth and seamless most of the time, and then randomly won't shift out of 1st. I can cut the key on and off and seems to reset and shifts just fine again. Is this the TCM? Anyone else have this problem?

 

Got an AT light?

 

an AT light? is this a warning light in the dash?

 

Does it stay on for a longer time than you would expect @ start-up?

 

hold that thought...I'm going to go out and crank it, but no, I've never noticed it before so I don't think it stays on longer than any of the others...

 

It's the O/D light that comes on and blinks longer if there's a prob with the trans but thankfully, that's not the case! Comes on and goes out in 2 secs like it's supposed to. It's really weird because i swear the trans shifts perfect most of the time! Just every once in a while after a stop it won't shift out of first but if I turn the key off and right back on works just fine..that's why I figured it's got to be something in the TCM....circuit going bad maybe? overheating? the car has over 200k on it.

 

Solenoids maybe.
