68RFE Input Drum 2007, used and ready to install. Fits the 68RFE. Ships fast from the USA.
If your 6.7L Cummins Ram 2500 or 3500 with the 68RFE came apart with burned overdrive frictions, a scored drum or a chewed-up tone wheel, this is the part that holds all of it together. It is a used 68RFE input drum clutch assembly that fits the transmission introduced in 2007, the first year Ram paired the 68RFE with the Cummins. Buyers usually land here after slipping on the 3-4 shift under a trailer, a P0871 code, or an input speed sensor code that would not go away.
ATSG's 68RFE service manual describes the input clutch housing as the home of three of the transmission's six clutches: the single-sided underdrive clutch, the single-sided overdrive clutch and the reverse clutch. The other three, 2C, 4C and low/reverse, are holding clutches in the case. Because every forward gear uses either underdrive or overdrive, and reverse uses the reverse clutch, this one housing is working in every gear the truck has. It spins at turbine speed, feeds apply oil to its pistons through the sealing rings on the input shaft, and carries the tone wheel that the input speed sensor reads. That last point matters more than most people expect: a damaged or loose tone wheel gives the controller a bad input speed signal even when the sensor itself is fine.
Transmission Digest calls the overdrive clutch the most common 68RFE failure, and it ties burnup to more than the drum: worn solenoid switch valve bore plugs, low line pressure and towing beyond the truck's rating all play a part. Check fluid level and smell with the transmission hot, then compare commanded and actual line pressure with a scan tool. Our 68RFE 3-4 clutch failure guide walks through the P0871 tests. If you are chasing an input speed code, read the 68RFE speed sensor guide first, because the tone wheel on this drum is one of the traps it covers. With the transmission apart, inspect the old housing for heat discoloration, cracked or worn lugs, grooved sealing ring lands and a bent or loose tone wheel.
This drum fits the 68RFE from the 2007 model year forward, which means Ram 2500 and 3500 pickups with the 6.7L Cummins diesel. The 68RFE received running changes over the years, including a redesign for 2019, so compare your old housing to the photo before ordering: tone wheel style, lug count, overall height and the sealing ring bore. If you would rather have us check, send your year and VIN and we will confirm fitment before it ships. The rest of the parts for this unit are on our 68RFE parts page, and if you want a drum listed by year range there is also the 2007-2018 68RFE input drum.
Heat is what kills these clutches behind a diesel, so a truck that tows should get a clean cooler and working thermal bypass at the same time.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The underdrive, overdrive and reverse clutches. The 2C, 4C and low/reverse holding clutches are separate and sit in the case.
It fits the 68RFE from 2007 on, which is the transmission behind the 6.7L Cummins. Because the 68RFE had running changes and a 2019 redesign, compare your old housing to the photo or send us your year and VIN to confirm.
Yes. The input speed sensor reads a tone wheel on this housing. A bent, cracked or loose tone wheel can set speed sensor codes or cause erratic shifts even with a new sensor installed.
New frictions and steels for the underdrive, overdrive and reverse packs, input shaft sealing rings, piston seals and filters. Check the pump, input shaft and solenoid switch valve bore during the same job.
No. It is a used assembly, and it comes with our 1-year warranty.
Mopar ATF+4 only, with the level set at operating temperature. After the repair, run the quick learn so the controller adapts to the new clutch clearances.
