42RLE Transmission parts

Transmission general data

Number of gears Transmission Type Drive ATF (full capacity) L ATF (change) L ATF type (recommended)
4 AT RWD 8,1-11 4 Mopar ATF+4

The 4-speed automatic transmission 42RLE was designed jointly with 42LE (front-drive) and was produced since 2003, installed on the powerful RWD Chrysler of the 300-series, Liberty Jeeps, Cherokee (V6 and V8) and Dodge pickups with engines from 2.7 l up to 4 liters.

In terms of design, the 42RLE is a simplified rear-driven version of the FWD A606 (42LE), which doesn’t have the differential, chain and some other elements for the front drive.

Technical issues and repair guidelines

The common repair kit for this transmission includes the following:

- repair kit of gaskets and seals.

- kit of friction components.

- kit of steel discs (less frequently)

The torque converter lock-up wear-out usually results in vibrations and wear of the pump bushing (which is the same in A604-A606 and is included in the kit of bushings). The problem with the pump bushing manifests itself in leakages through the pump seal. If this problem stays neglected, then it may lead to the oil pump replacement.

The block of solenoids in the 42RLE is a common reason for many issues in this family of automatic transmissions. The resource of this block is not a large one, and the ТСМ unit loads solenoids quite intensively forcing the torque converter locking at the first opportunity to increase acceleration characteristics of the car.

The Clutch Hub (2-4 Clutch) is a typical vulnerability of these transmissions. In terms of design, this automatic gearbox has problems with the hub and a sun gear. The problem is also provoked by shortages of the oil pressure.Sensor Output Speed (VSS) and Input (TSS) cannot endure high temperatures and oil contamination by the metal dust. Pump bushings, gaskets, pistons, planetary gears get out-of-service because of insufficient oil pressure. These typical problems also occur in the family А604-А606.

This reliable transmission may serve for a long time. But it should be kept in mind that engineers of Chrysler wanted to win the competition with other fast automatic transmissions, therefore they adjusted TCM settings in such a way that the accelerator pedal easily forces the transmission work 101% of its capabilities without leaving any reserves.
