The problem started with car going into limp mode and getting codes P0765,P0700 and P0734. I took the car to a shop and they replaced the Speed sensor and the UD Solenoid pack, The car was fine for 10 days the same issue they replaced the UD solenoid pack again and fixed some wires car was good for 4 days and now getting the P0765 and P0700 codes again. I cleared the codes and can drive the car around in 3rd gear without issue but drive it in drive and the codes will come back. HELP!

 

Could be the computer itself.

 

That's about all that's left by the sound of it.

 

Are you talking about the TCM?
