ATSG Repair Manual For The Chrysler Dodge 42RE Transmissions. Chrysler 42RE (A500-SE) Transmission found in 1993 and up Grand Cherokee. Covers assembly, dis-assembly, diagnosis, and troubleshooting.
The Chrysler 42RE (A500SE) is a 4-speed automatic transmission. Mechanical and hydraulic components in the 42RE are similar to those in the Chrysler 42RH (A500) transmissions. The major difference between them involves the method of producing governor pressure for shift speed control. The 42RE (A500SE) uses electronic components to develop governor pressure. Amechanical governor is used to generate governor pressure in the 42RH (A500) transmission.
First through third gear ranges in the 42RE are provided by the clutches, bands, overrunning clutch and planetary gear sets in the transmission unit. Fourth gear range is provided by the overdrive unit, which contains an overdrive clutch, direct clutch, planetary gear set and overunning clutch. The 42RE Overdrive Unit is shorter in length as a result of eliminating the mechanical governor, governor tubes and governor support.
The 42RE valve body transfer plate is completely new. It is redesigned to accept a new governor body and different hydraulic circuitry. The governor pressure solenoid and governor pressure sensor arc mounted in this body. The new valve body transfer plate channels line pressure to the governor pressure solenoid through the governor body. It also channels governor pressure from the solenoid into the governor pressure circuit It is the governor pressure solenoid that develops necessary governor pressure.
