65RFE Input Drum, new and ready to install. Fits the 65RFE. Ships fast from the USA.
If your Ram 1500, Durango or Grand Cherokee with the 65RFE six-speed has started flaring on the upshift into third or fourth, burned through a set of overdrive clutches, or came back from a rebuild still slipping, the input drum is one of the parts a rebuilder looks at hard. This is a new Mopar-branded input drum for the 65RFE, the machined housing in the photo with the splined center hub and the lugged lower section, sold so you can replace a cracked, flexed or worn housing instead of reusing it under fresh clutches.
The 65RFE is the six-speed evolution of the 545RFE, and it keeps the same basic layout as the rest of the RFE family. All of the driving clutches live in the input clutch assembly at the front of the gear train, turned by the input shaft. That assembly carries the underdrive, overdrive and reverse clutch packs, and the drum is the housing that holds their plates and pistons and routes apply oil to them through sealing rings. The holding clutches are in the case. Because this is a clutch-to-clutch transmission with no bands or sprags doing the work, every shift depends on these packs filling and releasing on time, which means the drum has to stay round, sealed and stiff.
Sonnax notes that overdrive clutch burnup happens across every RFE unit, the 65RFE included, and Transmission Digest describes the OE overdrive housing flexing at its unsupported top edge, which pulls clutch clearance out of spec and lets the thin plates overheat. A drum that has been through that cycle is often blued, distorted or worn at the ring lands, and new plates installed in it tend to fail again.
Rule out the hydraulic side first, because a drum will not fix a pressure problem. Check the fluid level hot, then look at line pressure and the overdrive pressure switch with a scan tool. Sonnax points to three areas when overdrive clutches keep burning: wear at the solenoid switch valve and its bore plugs, a restricted or leaking overdrive dribbler valve in the stator, and incorrect clutch clearance. Our RFE 3-4 clutch failure guide walks through the P0871 and switch valve checks, and the RFE valve body testing guide covers vacuum testing the bores. Once the unit is apart, inspect the drum for heat discoloration, a distorted top edge, cracks at the lugs and grooved sealing ring lands.
This listing is marked for the 65RFE without a year range. The 65RFE tag was used on Ram 1500 pickups with the 4.7L and 5.7L and on some Durango and Grand Cherokee V8 models in the early 2010s, and earlier versions of the same transmission are tagged 545RFE. Input clutch parts were revised across the RFE family over the years, so compare your old drum with the photo, including the hub spline count, lug pattern and overall height, and read the transmission tag. If you are not sure, send us your year and VIN and we will confirm the match before it ships. Parts for this family are on the 545RFE and 65RFE parts page.
A drum is normally replaced inside a full overhaul, so plan on new frictions, steels and seals from an RFE overhaul kit. Overdrive clutch failure also leaves debris in the cooler, so flush it or fit a fresh RFE transmission cooler, and if the unit ran hot the 65RFE TCC solenoid is worth checking at the same time.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The 65RFE is a development of the 545RFE and many input clutch parts are shared, but revisions were made over the production run. Compare the spline count, lug pattern and height of your old drum with the photo, or send us your year and VIN and we will confirm before it ships.
In the RFE family the input clutch assembly carries the underdrive, overdrive and reverse clutch packs. The holding clutches are in the transmission case. A problem with the drum can therefore show up as slipping in the upper gears or in reverse.
You can if the drum checks out, but a housing that has flexed, overheated or worn at the sealing ring lands will let the new clutches slip and burn again. If you see blue discoloration, cracks or a distorted top edge, replace the drum.
New frictions, steels, piston seals and sealing rings from an overhaul kit, plus a cooler flush. Also check the solenoid switch valve bore and the overdrive dribbler valve, since those cause repeat overdrive clutch failures.
Mopar ATF+4 only. Set the level with the engine running in Park at operating temperature, then perform a quick learn so the controller adapts to the new clutch clearances.
