So this happens when the transmission range sensor goes out, which is the most common, on the outside it can be a bad TCM but lets stick to the TRS fist.
P0706 - Transmission Range Sensor “A” Circuit Range/Performance
P0707 - Transmission Range Sensor “A” Circuit Low
U0402 - Invalid Data Received from TCM (Transmission Control Module)
The transmission range sensor is just inside the case of the transmission at the selector shaft. Clear the codes once the job is completed. Check out the images (below). Let us know if you need anything else.
