68RFE Clutch Module 2007, new and ready to install. Fits the 68RFE. Ships fast from the USA.
This is a new steel plate module for the 68RFE, made by Raybestos under part number 128753A (also cataloged as 837), for 2007-and-later Ram 2500, 3500 and 4500 trucks with the 6.7L Cummins. Our store title calls it a clutch module, and that is close, but the box holds steel plates only: four steels for the 4C clutch, three for the 2C clutch and two for the underdrive clutch. People land on this part when they have a 68RFE apart for slipping, a burnt smell or a flare under a trailer and the steels came out blued, warped or glazed. It is the half of the clutch job that a friction kit leaves out.
A clutch pack is frictions and steels stacked in turn. The steels are splined to the drum or case, the frictions to the part being driven or held, and when oil pushes the piston the stack clamps together. The 68RFE uses three input clutches and three holding clutches. The underdrive clutch drives the input gearset from first through fourth. The 2C and 4C clutches hold planetary members against the case to make second, third, fifth and sixth. A healthy steel is flat, with a fine finish that lets the friction bite and release cleanly. Heat ruins that. Once a steel is hot-spotted or dished, it grabs unevenly and slips, even against brand-new frictions.
Drop the pan first. Friction material and a burnt odor tell you a clutch has been cooking, and a clean pan sends you back to the solenoid pack and valve body. With the unit apart, lay each steel on a flat surface and check it with a straightedge, then look for heat color. GEARS Magazine puts 200 degrees F as the ideal maximum fluid temperature for these trucks and says fluid life is cut in half for every 20 degrees above it, which is why towing burns steels as well as frictions. Our 68RFE 3-4 clutch failure guide walks through the clutch-side causes, and the Ram 2500 Cummins problems guide covers what else to check before you open the case.
The module is listed for the 68RFE from 2007 on, which covers the 2007.5 introduction behind the 6.7L Cummins in Ram heavy-duty pickups and the 4500 chassis cab. The plate count is fixed at nine pieces for the UD, 2C and 4C packs. It does not include overdrive, reverse or low/reverse steels, and it has no frictions, seals or gaskets. Clutch stack-ups and housings changed over the run of this transmission, so count the plates you take out of each pack before you order. If anything does not match, send us your year and VIN and we will check it. The rest of the line is on our 68RFE parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is steel plates only: four 4C steels, three 2C steels and two underdrive steels. Buy a friction module for the same rebuild.
No. The overdrive, reverse and low/reverse packs are not part of this module. Reuse those steels only if they pass a flatness and heat check, or replace them separately.
Only if they are flat, free of heat spots and keep their surface finish. After a burned-clutch failure, most shops replace the steels, because a dished or glazed plate will slip against new frictions.
It is listed for the 68RFE from 2007 on. Later units had internal updates, so count the plates in each pack before ordering, or send us your year and VIN and we will confirm.
ATF+4 only. Check the level with the fluid hot and the engine idling in park, then run the quick learn with a scan tool.
