Anyone know if the Transmission Oil Temperature sensor is on all tranny's?
Mine is a '94 manual and I am getting the 636 and 639 codes... I thought this was strange since mine is manual... never really thought about tranny sensors on my car.

However... I did recently get two PCM's mixed up... one for an automatic and one for a manual. Didn't notice any driveability problems with either... perhaps I just have the wrong one on there?

Any thoughts?
