Code P0750 Chrysler Description

The Low Reverse (LR) is monitored at initially power-up, then every 10 seconds thereafter. The solenoids will also be tested immediately after a gear ratio or pressure switch error is detected. The P0750 code is detected when the Transmission Control Module (TCM) detects three consecutive solenoid continuity test failures, or one failure if the test is run in response to a gear ratio or pressure switch error

Code Tech Notes

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.
