42RLE Input Drum 2006, used and ready to install. Fits the 42RLE. Ships fast from the USA.
This is a used factory input clutch drum assembly for the Chrysler 42RLE four-speed, removed from a 2006 Jeep Liberty with the 3.7L V6 and two-wheel drive. It comes as shown in the photo: the drum with its input shaft in place, so you get the housing, shaft and splines from a running unit instead of hunting for a core. Liberty owners usually reach this page after a teardown turned up a cracked or heat-scarred drum, chewed plate splines or a shaft that will not seal, or after a junkyard unit they planned to swap turned out worse than their own. If your 42RLE flares on shifts, slips under throttle or keeps dropping into second gear, read on before you order.
The 42RLE uses clutches only, no bands, and the input drum carries three of them: the underdrive, overdrive and reverse clutches. It is splined to the input shaft and spins at turbine speed, so whatever the converter sends in has to pass through this assembly. Underdrive applies for first, second and third; overdrive applies in third and fourth; reverse is used only in reverse. The drum holds the piston bores, the oil feed ring lands and the steel plate splines. When those surfaces are cracked, scored or notched, apply oil leaks away or plates hang, and the transmission controller sees a ratio it did not ask for.
Start with a scan tool that reads clutch volume index values. ATRA explains that the CVI is the oil volume the controller learns for each clutch apply, and that it rises as frictions wear or a circuit leaks. A high underdrive, overdrive or reverse value with normal 2-4 and low/reverse numbers points into this drum. Our guide to 41TE and 42RLE slipping under load covers that test and the input hub bushing leak that can burn a new underdrive pack. If you have solenoid codes and the fluid still looks clean, check the electrical side in our Ultradrive limp mode guide first. Once the transmission is apart, look for cracks at the piston bores and outer lip, blue heat marks and worn plate splines on your old drum.
The listing documents one donor: a 2006 Jeep Liberty, 3.7L, 2WD, 42RLE. Other 42RLE units from the same period, such as 4WD Liberty, Wrangler and Dakota or Ram 1500 3.7L applications, are built around the same drum design, but internal changes do happen and the input shaft must match your unit, so lay your old assembly next to the photo and compare shaft length, spline count, the tone wheel teeth and any casting numbers. The front-drive 41TE drum from a minivan or sedan is not the same part, and 45RFE or 545RFE drums do not interchange. If you are unsure, send us the year and VIN and we will check it before it ships. Every part we carry for this family is on the 41TE and 42RLE collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Used. It is an OEM input clutch drum with its input shaft, removed from a 2006 Jeep Liberty 3.7L 2WD with the 42RLE. Install new frictions and seals with it.
The input drum is internal to the 42RLE and the 2WD and 4WD units share the same basic design, but compare your old drum and input shaft to the photo, or send us your year and VIN to check before ordering.
The underdrive, overdrive and reverse clutches. Underdrive works in first through third, overdrive in third and fourth, and reverse in reverse only.
ATF+4. Other fluids change friction behavior and can cause shudder or slip in this transmission.
Yes. Clear codes and run the Quick Learn procedure with a capable scan tool, then drive the vehicle so the controller relearns the clutch volume index for each clutch.
