Hi there, I recently got the code P0783 after back to back gearbox fault errors. Typically if I turn the car off and back on the fault goes away, it’s happened a handful of times within the past few years. Any idea how to fix this issue or what may cause it? I have a 2004 4.2 6 speed XKR. Could it be the solenoids? Where should I start? I also got code C1145 (Front Right Wheel Speed Sensor Input Circuit Failure) and (Intake Air Temperature (IAT) Sensor Circuit Intermittent High Voltage).

 

The C1145 is 99% the link harness to the speed sensor.
The intake air temp sensor (P1111 if that is what it is) is a FALSE FLAG.

P0783
ECM Torque signal fault
Transmission mechanical failure

 

What should I start by replacing or ordering?
