42RLE Overhaul Kit 2003-11, new and ready to install. Fits the 42RLE. Ships fast from the USA.
If your Jeep Liberty, Wrangler, Dodge Dakota, Durango, Nitro or Mitsubishi Raider has a 42RLE that weeps ATF+4, takes a second to drop into gear on a cold morning, or is already on the bench waiting for clutches, this is the seal and gasket set that puts it back together. It is a new overhaul kit for the 42RLE four-speed, listed for 2003 through 2011 builds, and the product description covers 2003-2012 Dodge, Ram, Jeep, Chrysler and Mitsubishi models with this transmission. The description lists paper and rubber gaskets, O-rings, lip seals, metal-clad seals, sealing rings and a pan gasket. The photo shows the kit sealed in its bag with the gasket sheet, rubber rings and seals visible. Frictions, steels and a filter are not part of it.
Chrysler built the 42RLE as the longitudinal, rear-drive cousin of the 41TE. There are no bands. Each of the four forward gears and reverse comes from applying one or two of five hydraulic clutches, and the controller swaps them with precise timing. That timing depends on how much oil each clutch circuit takes to fill. The sealing rings on the input shaft and pump support carry apply oil into the spinning drum. Gaskets and O-rings seal the feed passages between the case, the valve body and the piston retainers. The metal-clad seals keep fluid in at the front of the pump and the output end. When those parts age and harden, fill volumes climb, shifts slur, and pressure that should be holding a clutch ends up in the pan. A full set of fresh soft parts is the base every 42RLE rebuild starts from.
Start outside the case. Clean the transmission, drive it, and trace any leak back to its source; a gasket or seal leak on its own is a reseal job and this kit covers it. For shift problems, connect a scan tool that reads Chrysler clutch volume index values. ATRA's technical bulletin for this transmission family lists the normal range for each clutch. One clutch reading high means oil is escaping in that circuit; all of them high points to line pressure or bushing wear instead. Our guide to slipping under load walks through that diagnosis, and the Ultradrive limp mode guide helps if you are seeing solenoid or electrical codes rather than slip.
This kit is listed for the 42RLE in 2003-2011 vehicles, and the product description extends that to 2003-2012 Dodge, Ram, Jeep, Chrysler and Mitsubishi applications. The 42RLE changed during that span: 2007 and later units moved to variable line pressure with an added line pressure solenoid, so small sealing details can differ between early and late cases. Match your old gaskets to the new ones before you start, and if you are not sure which version you have, send us your year and VIN before ordering. Browse every part we carry for this family on the 41TE and 42RLE parts page.
If the clutch packs are burnt, pair this with the 42RLE rebuild kit with frictions, steels and filter. If the unit also had a solenoid fault, the 42RLE shift solenoid block pack is worth checking while the pan is off. After a rebuild, clear the adaptive values and run the quick learn procedure with a scan tool so the controller relearns the new clutch volumes.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is the gasket and seal side of a rebuild: paper and rubber gaskets, O-rings, lip seals, metal-clad seals, sealing rings and a pan gasket. Clutches, steels and the filter are sold separately.
The kit is listed for 2003-2011 42RLE units and described for 2003-2012 Jeep, Dodge, Ram, Chrysler and Mitsubishi applications, which covers the Liberty. Because 2007 and later cases are variable line pressure units, compare the old gaskets with the new ones, or send us your year and VIN to confirm.
Yes. If the leak is at the pan, a cover, the front pump seal or the output, the gaskets and seals in this kit handle a reseal. Internal pressure leaks need the transmission apart to replace the piston and drum seals.
ATF+4 only. Fill it, run the engine, and set the final level with the fluid at operating temperature.
After an internal rebuild, yes. Reset the transmission adaptives and run the quick learn so the controller relearns clutch fill volumes. Skipping it can leave harsh or slow shifts until it adapts on its own.
