Code P0752 2016 GMC Sierra Description

The P0752 diagnostic trouble code (DTC) for the 2016 GMC Sierra indicates an issue with the Shift Solenoid Valve 1 Performance being stuck on. This code typically signifies that the transmission is not shifting properly due to a malfunction in the solenoid valve responsible for controlling the fluid flow within the transmission. The shift solenoid valve plays a crucial role in the smooth operation of the transmission by regulating the hydraulic pressure that facilitates gear changes. When this valve gets stuck in the "on" position, it can lead to erratic shifting, harsh gear changes, transmission slipping, and even the transmission getting stuck in a single gear.

Tech Notes for P0752 2016 GMC Sierra

When 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 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 transmission mechanical failure, and that the transmission will need to be rebuilt or replaced.
