68RFE Master Rebuild Kit 2010-2018, new and ready to install. Fits the 68RFE. Ships fast from the USA.
A 2010 through 2018 Ram 2500 or 3500 with the 6.7L Cummins that keeps burning the overdrive clutch usually has a valve body problem, not just a clutch problem. Despite the "master rebuild kit" name on the listing, the product photo shows a billet valve body repair kit for the 68RFE: a machined aluminum channel plate, a steel separator plate with matching gaskets, five red aluminum accumulator pistons, a switch valve and plugs, O-rings, a full set of bolts and a steel reinforcement strip. It is for the owner or shop who wants the hydraulic side of the transmission sealed before trusting new clutches to it.
The 68RFE builds every gear by feeding pressure through the valve body to six clutch packs. The cast channel plate carries that oil in worm tracks, and over time those tracks erode until circuits leak into each other. GEARS Magazine calls this track erosion the most common cause of 68RFE overdrive clutch burn-up, tied closely to the extra torque of tuned engines, and lists a billet channel plate as one of the two fixes that is working in the field. A billet plate is machined flat and thicker than the casting, so it does not warp or wash out the way the original does.
The accumulators cushion each clutch apply. When the bores wear, apply pressure drops and shifts go soft. GEARS notes the author's preference for aluminum accumulator pistons over plastic ones, and Sonnax lists dedicated 68RFE accumulator piston kits for the same wear; the five billet pistons in this kit serve that purpose.
Pull the valve body, separate the halves and look for washed-out tracks and shiny wear around the separator plate holes. Vacuum test the switch valve bore, which Sonnax identifies as the heaviest wear point because the plug strokes on the 1-2, 2-3 and 3-4 shifts. Our 68RFE valve body testing guide shows the full procedure, and the Ram 2500 Cummins common problems guide explains how towing heat and power mods tie into these failures.
Listed for the 68RFE from 2010 through 2018, the 6.7L Cummins Ram 2500 and 3500 before the 2019 redesign. Valve bodies changed during that run, so lay your separator plate next to the one in the photo and check that the bolt holes and feed holes line up, or send us your year and VIN. A 2019 or newer truck needs a 2019-up kit. The full year-by-year lineup is in the 68RFE collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The photo shows a valve body repair kit: billet channel plate, separator plate, gaskets, five accumulator pistons, a switch valve and plugs, O-rings and bolts. Clutch packs are not included.
It is listed for 2010 through 2018. Earlier and 2019-up valve bodies differ, so send us your year and VIN before ordering for a truck outside that range.
Track erosion happens on stock trucks too, just more slowly. If your valve body shows washed-out tracks or fails a vacuum test, it is worth fixing whether the engine is tuned or not.
The valve body comes out through the pan, so the work can be done in the truck, but if the overdrive clutch has already burned you will need to pull the unit.
Mopar ATF+4 only, level set at 160 degrees F or hotter, then a TCM quick learn and a road test through all six gears.
