Chrysler 42RE - Automatic Transmission Service Group PDF

The Chrysler 42RE (A500SE) is a 4 speed automatic transmission. Mechanical and hydraulic components in the 42RE are similar to those found in the 42RH (A500) transmissions. The major difference between them involves the method they use to produce governor pressure for shift control. The 42RE (A500SE) uses electronic components to create governor pressure and the 42RH (A500) uses a mechanical governor to create governor pressure.

First through third gear in the 42RE (A500SE) are provided by the clutches, bands, low roller clutch and planetary gear sets located in the transmission main case. Fourth gear is provided by the overdrive unit, located in the extension housing and contains an overdrive clutch, overdrive direct clutch, overrun roller clutch and overdrive planetary gear set. The 42RE (A500SE) Overdrive Unit is shorter than the 42RH (A500), resulting from elimination of the mechanical governor, governor support and governor oil tubes.

The 42RE valve body transfer plate is completely new. It is redesigned to accommodate a new governor body and different hydraulic circuitry. The governor pressure solenoid and governor pressure sensor are mounted on this body. It also channels governor pressure from the solenoid into the governor pressure circuit for the 1-2 and 2-3 shift valves in the valve body. The 3-4 shift is activated electronically with a shift solenoid.
