Code P0750 Mitsubishi Description

The P0750 diagnostic trouble code (DTC) in a Mitsubishi indicates a malfunction in Shift Solenoid 'A' within the transmission system. The shift solenoid is responsible for controlling the flow of transmission fluid to engage and disengage gears, allowing the vehicle to shift smoothly between gears. When this solenoid malfunctions, it can lead to issues with shifting gears, resulting in poor performance, reduced fuel efficiency, and potential damage to the transmission system over time.

Tech Notes for P0750 Mitsubishi

When the a transmission solenoid is malfunction, 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 P0750 code is detected when TCM detects an improper voltage drop when it tries to operate the solenoid valve.
