68RFE Shift Kit 2018, new and ready to install. Fits the 68RFE. Ships fast from the USA.
This listing sits with our shift kits, but it is a full rebuild package for the 68RFE behind the 6.7L Cummins: an overhaul gasket and seal kit (including the valve body and stator gaskets), a set of BorgWarner clutches, molded pistons, a spin-on filter and a TransGo shift kit, all in one box. It is aimed at the 2007-2018 Ram 2500 and 3500 owner whose truck is slipping under a trailer, flaring into fourth or fifth, burning the overdrive pack, or coming back with a pan full of friction material after a few years of towing. If the transmission is already coming out of the truck, buying the soft parts and the hydraulic upgrade together saves a second teardown.
The 68RFE is a six-speed electronic automatic with three input clutches (underdrive, overdrive and reverse) and two holding clutches, all applied by solenoid-controlled pressure through the valve body. The computer learns each clutch's fill time, and Sonnax notes that clutch clearance directly affects that fill time, which is why a rebuild with fresh frictions and correct clearances matters as much as any spring change. The rebuild half of this package replaces the wear items: frictions, seals, molded pistons and gaskets. The TransGo half addresses the hydraulic weak spots TransGo lists for 1999-2018 RFE units, including rough or sliding converter lock-up, TCC slip codes, low line pressure code P0868 and converter drain-back, with a drop-in torque converter limit valve system, a heavy-duty accumulator cover, a self-cleaning low/reverse switch valve and a heavy-duty snap ring for the input drum pressure plate.
Scan for codes and look at the fluid first. A slip that comes with ratio error codes and burnt ATF+4 usually means worn clutches, and that is a rebuild job. A harsh shift with clean fluid can be software or adaptives instead, so read our guide on 68RFE Ram 2500 Cummins common problems before committing to a teardown. If the complaint is a truck that will not use the upper gears, work through 68RFE won't shift into overdrive to separate strategy and limp mode from a real clutch failure. Codes such as P0841, P0871 or P0988 on a high-mileage unit often trace to a worn solenoid switch valve bore, which a rebuild kit alone does not fix.
Our product name reads 2018, but the package is built for 2007 through 2018 68RFE units in the Ram 2500, 3500 and cab-chassis trucks with the 6.7L Cummins. It is not the right kit for a 2019 or newer truck: Sonnax documents that the 2019-up 68RFE moved to a blue connector solenoid pack with separate TCC and reverse clutch control, and TransGo sells a different kit for those years. Shop the full range on our 68RFE parts page. Because Ram made running changes inside the 2007-2018 span, send us your year and VIN before ordering and we will confirm it against your build.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is a 68RFE rebuild package: overhaul gaskets and seals with the valve body and stator gaskets, BorgWarner clutches, molded pistons, a spin-on filter and a TransGo shift kit.
No. This package is for 2007-2018 68RFE units. The 2019-up 68RFE changed its solenoid pack and control layout and uses a different TransGo kit. We stock 2019-up parts on our 68RFE page.
Yes. The clutches and pistons are internal parts, so this is a full out-of-truck rebuild. The shift kit portion goes in while the valve body is apart on the bench.
ATF+4. Do not use a universal multi-vehicle fluid in place of it. Check the level hot, with the engine running, using the dipstick procedure for your model year.
Yes. New clutches change fill volumes, so clear the codes, run the quick learn or adaptive reset with a scan tool, and drive the truck through all gears so the computer relearns each shift.
Inspect the solenoid switch valve bore and the pump, flush the cooler and lines, and replace any hard parts that are worn or heat-damaged. A worn switch valve bore calls for a switch valve kit or a replacement valve body.
