i have a 97 12v. when cold i have to drive about 7-10 miles and then tranny
does the 4th od lockup. until then nothing i do, i.e. shutting off engine,
pumping pedal to rotate tps, multiple
key cycles help. only when i think the computer is seeing a warm tranny will
it go into 4th od. i know this shift is electronic but somethin is keeping it from happening. this problem just showed it ugly head. maybe od switch on brake pedal?

Theres a temperature sensor in the trans, that won't allow lock-up until the fluid warms up a little. Yours is likely bad.
