P0700, P0743, P0748, and P0753 codes

When making a u-turn earlier today my check engine light came on and the transmission went in to limp mode. I checked the codes and got the above codes, all transmission related. The codes come back immediately after clearning them. Anyone have any ideas what to look at?

THANKS!

I've also discovered that only the P0700 code appears when the ignition is switched on and the Trans control module is disconnected. The fuses and relays are functioning properly, I'm starting to think I need a new TCM.

Anyone know a good place to get a TCM other than the stealer?

I checked and cleaned both the connector and the transmission and the 3 at the PCM. Both seemed fine. I am going to check for voltage at the transmission connector as well as the solenoid resistance.

Does anyone know where I can find a wiring diagram or pin-out for the connectors?

Thanks again!
