Calibration Of The Engagement Pressure For The Transmission Clutch
Incorrect transmission clutch pressure adversely affects the life of the transmission. Submodes 31 through 33 are used in order to set the transmission clutch pressure of the direction clutches (No. 1 through No. 3). In this process, the service technician adjusts the electrical current that is sent to the transmission solenoid valve in order to obtain the specified pressure for the transmission clutch. The calibration of the transmission clutch pressure must be performed prior to the transmission clutch fill calibration (submode 40).The transmission system must be calibrated if any of the following conditions have occurred:
A transmission solenoid valve has been replaced or cleaned.
A different power train ECM has been installed.
New flash software has been flashed into the ECM.
A transmission clutch has been rebuilt.
The transmission clutch does not shift correctly.
