66RFE Clutch Module 2012-2013, new and ready to install. Fits the 66RFE. Ships fast from the USA.
This is a Raybestos friction clutch pack, part number RCP96-376, built for the 66RFE six-speed in 2012 and 2013 gas-engine Ram heavy-duty trucks: the Ram 2500 and Power Wagon with the 5.7L Hemi and the 3500 chassis cab. People shopping for it usually have a truck that flares on the upshift while towing, slips in fourth or above on a grade, or showed black, burnt fluid and lining on the pan magnet at the last service. The pack replaces every friction plate in the unit in one box, so the clutches going back together all start at the same wear point.
For 2012 Chrysler built the 66RFE by putting the 68RFE gearset and clutches inside a 545RFE-style case. There are no bands. Every forward gear and reverse comes from two multi-plate clutches applied together: underdrive, overdrive and reverse drive parts of the gear train, while 2C, 4C and low/reverse hold members to the case. The controller fills each clutch through the solenoid pack and checks the result through pressure switches and speed sensors. A glazed or thin friction takes longer to grab, the engine flares during the change, the extra slip makes heat, and the heat finishes off the rest of the pack.
Raybestos lists the RCP96-376 contents by clutch, with the plate thickness for each:
It is frictions only. Steels, seals, sealing rings, gaskets and filters are not included.
New frictions will not survive a control problem. Check the level hot, drop the pan, and read the filter and magnet. Lining and a burnt odor mean the unit needs a teardown; a clean pan points back to the solenoid pack, wiring or valve body. Since the 66RFE runs the same clutch design as the diesel unit, the overdrive failure pattern in our 68RFE 3-4 clutch failure guide applies here, and the RFE valve body testing guide covers the switch valve leaks that burn a fresh overdrive pack.
Raybestos catalogs this pack for the 2012-2013 66RFE only. The 2014-and-newer 66RFE takes a different pack, so do not mix years, and do not use this in a 65RFE from a Ram 1500 or Durango, which has the older 545RFE internals. A unit that was rebuilt before may have an aftermarket overdrive housing with a different plate count, so lay out the old plates by drum and count them against the list above. If you are not sure of your build, send us your year and VIN. For a 2007-and-up rated alternative, see the RCP96-232 66RFE clutch module. Everything else for this unit is on the 66RFE parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The 66RFE went into gas-engine Ram heavy-duty trucks starting in 2012: the Ram 2500 and Power Wagon with the 5.7L Hemi and the Ram 3500 chassis cab. If your truck is a 2012 or 2013 in that group with the six-speed automatic, it has the 66RFE, not the diesel 68RFE.
No. Raybestos lists the RCP96-376 for 2012-2013 only and catalogs a separate pack for 2014-on units. For a later truck, send us your year and VIN and we will point you to the right parts on the 66RFE page.
No. The box holds friction plates for all six clutches and nothing else. Plan on reusing good steels or buying new ones, and use a soft-parts or master rebuild kit for the seals, sealing rings and gaskets.
Often the overdrive clutch is burnt, because it applies in all three of those gears. But the burnt pack is usually the result of a leak in the valve body switch valve or a weak pump. Fix the cause during the rebuild or the new frictions will fail the same way.
Mopar ATF+4 only. Soak the frictions in ATF+4 before assembly, set the level with the fluid hot, then run the quick learn with a scan tool so the controller relearns clutch fill times on the new plates.
