Code P0762 Audi Description

The P0762 diagnostic trouble code for Audi indicates that the Shift Solenoid 'C' is stuck on. The shift solenoid is a crucial component in the transmission system that controls the flow of transmission fluid, which in turn controls the shifting of gears. When the solenoid is stuck in the "on" position, it means that it is constantly sending fluid pressure to a specific clutch pack, causing the transmission to remain in a particular gear. This can lead to issues such as harsh shifting, delayed shifting, or the inability to shift gears at all.

Tech Notes for P0762 Audi

When the a transmission solenoid is stuck on, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. If the transmission fluid is very dirty, it is recommend changing the transmission fluid and if possible removing the transmission pan for further diagnosis. Excessive debris or metal particles on the transmission pan could be an indication that there is a transmission mechanical failure and that the transmission will need to be rebuilt or replaced.

When is the Code Detected?

The P0762 code is detected when the gear required by the ECM does not match the actual gear when vehicle is driven.
