Code P0752 Pontiac Description

The P0752 diagnostic trouble code (DTC) for Pontiac vehicles specifically refers to the 1-2 Shift Solenoid Valve Performance issue, indicating that there is a problem with the transmission's ability to shift into second or third gear. The shift solenoid valve is a crucial component of the transmission system that controls the flow of transmission fluid to engage the appropriate gear for smooth shifting. When this solenoid malfunctions, it can lead to a lack of engagement or delayed shifting between gears, resulting in poor vehicle performance and potential long-term damage to the transmission system.

Tech Notes for P0752 Pontiac

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 P0752 code is detected when the gear required by the ECM does not match the actual gear when vehicle is driven.
