42RLE Input Drum 2010, used and ready to install. Fits the 42RLE. Ships fast from the USA.
A 2010 Jeep Liberty, Wrangler or Dodge Nitro with the 42RLE that slips in the upper gears, flares on the 2-3 shift or loses reverse has usually hurt something inside the input clutch drum. This listing is a used original 42RLE input drum for 2010, pictured with the input shaft installed through the center. It is for the rebuilder or shop whose own drum came out cracked, burnt or with damaged splines, where new frictions alone would not save the job.
Inside the 42RLE, power from the torque converter turns the input shaft, and the input drum turns with it. Three clutch packs ride in this drum. The underdrive clutch drives the gearset in first, second and third, the overdrive clutch takes over for third and fourth, and the reverse clutch works only in reverse. There are no bands; the controller times each shift by filling one clutch while it vents another. That makes the drum's sealing surfaces and piston bores critical. A small leak changes how fast a clutch fills, and the controller reacts with a flare, a bind-up or a ratio code.
A 2010 42RLE uses electronic line pressure control, which Sonnax notes arrived in this family starting in 2007. That is useful to know, because a line pressure solenoid or sensor fault can mimic a slipping clutch. Rule that out, then read the clutch volume index values with a scan tool. ATRA's 41TE/42LE technical bulletin gives normal ranges of 24 to 70 for underdrive and 48 to 150 for overdrive; numbers well over those, while 2-4 and low/reverse stay normal, aim at the input drum. Our slipping-under-load guide for the 41TE and 42RLE explains the test step by step, and the Ultradrive limp mode article covers the electrical faults to clear first.
This drum is listed for 2010 42RLE transmissions. In 2010 the 42RLE was behind the 3.7L V6 in the Jeep Liberty and Dodge Nitro and the 3.8L V6 in the Jeep Wrangler, among other applications. The listing does not name a donor vehicle, so match the part to your own assembly: compare input shaft length and splines, tone wheel teeth and casting marks on the drum, or send us your year and VIN and we will confirm it. It does not fit front-drive 41TE transaxles or the 45RFE and 545RFE. See the full family on our 41TE and 42RLE collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The 2010 Jeep Liberty and Dodge Nitro with the 3.7L V6 and the Jeep Wrangler with the 3.8L V6 are the common ones. Send your VIN if you want us to confirm your transmission.
The photo shows the drum with the input shaft installed. You receive the assembly as pictured; plan on new frictions and seals.
Yes. 2010 units use electronic line pressure control, and low or erratic pressure can cause flares that feel like clutch slip. Check pressure codes and readings before tearing down.
ATF+4 only, with a new filter.
Yes. Run the Quick Learn with a scan tool and then drive so the controller relearns the clutch volume index for each clutch.
