i was driving my 89 3.0 2dr, last night i was driving to school 2.5 hrs away. it was driving smooth and then i was getting off the interstate and that light came on. i said no worries i am pulling over anyways. I was at the gas station for over and hour and check the tranny fluid level twice. it was a little over full when hot but definitely not low. did not see any leaks. so i drove over an hour while it was cool outside making sure not to get the engine over 200 rpms hoping that would not strain the tranny. but it acted smooth and fine. Fast forward this afternoon i needed to move it. i know it has cooled off since last night. Crank it up and the light is still on. What is going on. Is there a sensor that tripped and its staying on or is it grounding out somewhere? i like these monteros but it is definitely been a love hate relationship.
