68RFE Clutch Module 2013-2018, new and ready to install. Fits the 68RFE. Ships fast from the USA.
The name on this listing says clutch module, but the part is a RevMax ZeroStat transmission cooler thermostatic bypass, part number 68RFE-929AA, for 2013-2018 Ram 2500 and 3500 pickups with the 6.7L Cummins and the 68RFE or Aisin AS69RC automatic. We are saying so up front. A lot of people searching for a 68RFE clutch module have a truck that cooked its overdrive pack on a tow, and the factory bypass valve is one of the reasons that happens. This part belongs in that repair, but it contains no friction plates.
On the 2013-and-newer trucks the cooler lines run through a thermostatic bypass block. When the fluid is cold, a thermal element keeps ATF from going to the cooler so the transmission warms up; when it is hot, the element is supposed to open and send fluid through the cooler. RevMax reports two problems with the factory part. Some units stick in the cold, closed position, so the fluid never reaches the cooler and the transmission overheats. And even when it works, RevMax says an internal orifice cuts cooler flow by 87 percent. Their billet 6061 aluminum block removes the thermal valve and the orifice, so fluid goes to the cooler all the time, and it adds cooling fins on the body.
Transmission Digest calls the overdrive clutch the 68RFE's most common failure point. That clutch carries fourth, fifth and sixth gears, the ones a truck lives in while towing. Its thin steels are the pack's heat sink, and once the fluid runs hot they warp and the frictions glaze. A rebuilt unit put back on a truck with a sticking bypass is set up to burn the same pack.
Watch transmission temperature on a scan tool or gauge under load and compare the inlet and outlet cooler line temperatures once it is hot. If the cooler is not getting flow, the bypass is the first suspect. If the clutches are already slipping, see our 68RFE 3-4 clutch failure guide for the teardown checks, and the Ram 2500 Cummins common problems guide for the other heat-related failures on these trucks.
RevMax lists the 68RFE-929AA for 2013-2018 Ram 2500 and 3500 6.7L Cummins with the 68RFE or AS69RC. The 2010-2012 and 2019-up trucks use different bypass parts that do not interchange, so check your model year first. If you need friction plates, our BorgWarner 68RFE friction module is the clutch part, and the rest is on the 68RFE collection page. Send us your year and VIN if you are unsure.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. Despite the listing name, it is a RevMax ZeroStat cooler thermostatic bypass, part number 68RFE-929AA. It protects the clutches by keeping fluid flowing to the cooler, but it contains no friction or steel plates.
2013-2018 Ram 2500 and 3500 with the 6.7L Cummins and either the 68RFE or the Aisin AS69RC. It does not fit 2010-2012 or 2019-and-newer trucks, which use different bypass parts.
Yes, the install sheet calls for two black O-rings and two connector clips that go on the quick-connect side of the bypass. The factory green O-rings on the cooler lines are normally reused.
RevMax designed it to send fluid to the cooler all the time instead of waiting for the fluid to get hot. If you drive in severe cold, consider that the transmission will take longer to warm up.
Mopar ATF+4 only. Some fluid is lost when the lines come off, so top off and set the level with the transmission at operating temperature.
