Code P0796 Description

The diagnostic trouble code P0796 indicates that the Pressure Control Solenoid 'C' is stuck off. This solenoid is responsible for controlling the fluid pressure in the transmission, which is crucial for smooth shifting and overall transmission performance. When this solenoid is stuck off, it can lead to issues such as harsh shifting, delayed shifting, transmission slipping, and even the transmission not shifting at all. If left unresolved, this can cause further damage to the transmission system and potentially lead to a complete transmission failure.

Tech Notes for P0796

When a transmission solenoid has malfunctioned, 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 dirty, it's recommended to change the transmission fluid and if possible, remove the transmission pan for further diagnosis. Excessive debris or metal particles on the transmission pan could be an indication that there is a mechanical transmission failure, and that the transmission will need to be rebuilt or replaced.
