hello all, i am a newbe, but i have read about this problem in a couple of places, but never any answers or fixes, after sitting overnight, my trans wont hit overdrive till it is warmed up , about 2-5 miles, and then come to a complete stop. the fluid is full and clean, it has 106k on her, and trans is original, i checked for codes, none. Any help in this area is appreciated.....

many thanks

For the thousandth time, I'm pretty sure this is covered in the owners manual.


I know for a fact I've posted no less that 4 times on this subject.


Page 55 in my 89 Supra owners manual, and page 44 in my 94 T100 owners manual.

well i have changed the thermostat and rad, it did it before and after that . and why does it go into overdrive after a complete stop ?

There is a temp sensor that controls the computer that controls the OD, but don't ask me where it is...


You shouldn't be cold starting and driving your trans anyway...

Just let it warm up all the way for you start driving it... That might be the simplest fix.
