My 1993 jeep grand cherokee limited will not shift if you put it in drive. if you shift it manually it shifts just fine. my shift pattern is PRND21. People have told me that there is a tcc relay under the hood but i cant find it amungst the 30 relays and 100 fuses. I have checked all the fuses and changed the fluid and filter and flushed the system. If anyone can help it would be greatly appreciated. I you need more info just ask.

 

It could be your Transmission Control Module. For the AW-4 it's near the steering column support. For the 45RFE it's under the hood next to the coolant over-flow reservoir.
It might also be the Throttle Valve Cable that connects between the throttle body and the trans. It could need adjusting or be damaged/disconnected. JMO
