When making a 3-point-turn (probably when going from D->R->D) earlier today my check engine light came on and the transmission went in to limp mode. I checked the codes and got the following codes, all transmission related:
P0700 Transmission Control System Malfunction
P0743 Torque Converter Clutch Circuit Electrical
P0748 Pressure Control Solenoid Electrical
P0753 Shift Solenoid A Electrical

The codes come back immediately after clearning them. So far I have checked and cleaned the electrical connections at the transmission and PCM on the firewall with no luck. I did discover that it only throws the P0700 code if I leave the PCM unhooked and turn the key to the "run" position. I am suspection a bad PCM at this point. Any ideas?

THANKS!

 

Could be relay in your fuse box under the hood try changing it with another one. Mine through those codes and it was the relay.

 

I checked the relay, switched it with a different one, and checked the fuse. All checked out OK and the problem still persist. Thanks!
