Code P0772 Mazda Description

The P0772 diagnostic trouble code for Mazda vehicles indicates that the shift solenoid 'E' is stuck on. This solenoid is responsible for controlling the flow of transmission fluid to engage a specific gear within the transmission. When this solenoid is stuck in the on position, it can lead to issues with shifting gears smoothly and efficiently. This can result in rough shifting, delayed shifting, or even the inability to shift gears at all. If left unresolved, it can lead to further damage to the transmission system, potentially resulting in costly repairs.

Tech Notes for P0772 Mazda

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.
