68RFE Clutch Module 2007-2018, new and ready to install. Fits the 68RFE. Ships fast from the USA.
Despite the clutch module name on this listing, the part is a RevMax ZeroFlex billet oil pump body, manufacturer part number 68RFE-626, for the 68RFE in 2007.5-2018 Ram 2500 and 3500 pickups with the 6.7L Cummins. We are telling you up front because many people who search for a 68RFE clutch module are rebuilding a unit that burned its overdrive pack. A warped pump body is one of the hidden reasons a fresh set of frictions does not last, so this part belongs in that conversation. It is just not a friction pack.
Every clutch in a 68RFE is applied by oil the front pump makes, and the pump has no gasket between its halves. It seals only because the body, the separator plate and the stator are flat against each other. RevMax reports that cast bodies warp after thousands of heat cycles, that most used bodies they inspect are more than .005 in. out of flat, and that some reach .020 in. Oil that leaks across those faces never reaches the pressure regulator or the clutch circuits. The overdrive clutch carries fourth through sixth gear, and Transmission Digest identifies it as the 68RFE's most common failure point. It is the first pack to suffer when apply pressure sags under a trailer. A rebuilder who installs new frictions on a warped pump is rebuilding the same failure.
Check hot line pressure against what the controller commands. GEARS Magazine gives 60 to 70 psi at idle, commanded and actual, at a 22 to 24 percent duty cycle as a healthy 68RFE baseline, so a gap between the two numbers points at a leak or a weak pump. Then check the parts on the bench. Do not sand a warped body flat. RevMax explains that a new factory pump has only about .002-.003 in. between the gears and the separator plate, so taking metal off the face lets the gears rub. Our 68RFE pump failure guide covers the full pump inspection. The 3-4 clutch failure guide covers the valve body leaks that burn the overdrive pack whether or not the pump is flat.
RevMax lists the body for 2007.5-2018 68RFE transmissions in Ram 2500 and 3500 Cummins trucks, in stock or aftermarket builds. The 2019-up 68RFE is not listed. You receive the pump body half only, with no gears, stator, separator plate or seals, and no core is required. It accepts a new, used or rebuilt stator half, and RevMax says the stator can be resurfaced conventionally if its valves pass inspection. Send us your year and VIN if you are unsure which 68RFE your truck has, and see the 68RFE collection for the rest of the parts.
According to RevMax, the body is CNC machined from 6061 billet, nearly three times as thick as the casting, with revised worm tracks and a face held flat within .0003 in.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The listing name is wrong. It is a RevMax billet oil pump body, part number 68RFE-626. If you need frictions, look at the BorgWarner 68RFE friction module or the other friction kits in our 68RFE collection.
No. It is the pump body half only. You reuse or replace the gears, and you reuse a stator half that has been inspected and resurfaced, or install a new or rebuilt one.
It is listed for 2007.5-2018 68RFE units only. The 2019-up transmission went through design changes and is not on the fitment list, so send us your VIN if you are unsure.
RevMax warns against it. Sanding the face reduces the very small gear-to-separator-plate clearance of a new pump, and the gears can then rub or bind against the plate.
No core is required for this pump body.
