Please help i just bought this 01 cummins was told by a transmission shop it need gov pressure solenoid and transducer. Transmission would not shift on its own if i put it in D it's in 3rd if i shift manually from neutral to 1st then 2nd then 3rd works fine holds no slipping. But i have no od. So i replaced with the "RE" HD Master Electrical Kit 00 Up from electrical advantage pretty much replaces everything electrical on the transmission. Checked codes and it is showing;

P0713 transmission fluid temp sensor A high Voltage greater than 3.76 volts

P0753 Transmission 3-4 Shift Soleniod/Transmission Relay Circuits An open or shorted circuit detected in the overdrive solenoid control circuit or trans relay circuit in JTEC RE transmissions.

and a P1763 Governor Pressure Sensor Volts Too High Voltage greater than 4.89 volts.

I am thinking i cant be the only person to have this problem please if anyone has a clue on who i should call or what fixed this problem on yours feel free to post away ive searched darn near every forum i could think of still no answer..

 

I don't know much about auto trannys but sounds like you have a short or some wires crossed. Other then that I can't help you out much man. Maybe some one else will chime in and shed some light on this situation.

 

Yea ended up being a broken main harness connection to transmission
