68RFE Overhaul Kit 2011-2023, new and ready to install. Fits the 68RFE. Ships fast from the USA.
If your 2011-2023 Ram 2500 or 3500 with the 6.7L Cummins pulls a trailer, the fluid in the 68RFE is the first thing that wears out, and dark, hot-smelling ATF is the usual warning before shift quality starts to go. Despite the overhaul kit name on this listing, this is not a set of seals for a teardown. It is a complete pan-drop service kit: ten quarts of full synthetic fluid built to the ATF+4 spec, a new sump (pan) filter, a new spin-on filter, a pan gasket, and a tube of RTV gasket maker, packed together so the job is done in one trip under the truck.
The 68RFE runs two filters. The sump filter sits on the valve body inside the pan and screens everything the pump pulls in. The spin-on filter on the outside of the case cleans fluid on its way back from the cooler. When either one loads up with clutch material, the pump works harder, cooler flow drops and the fluid runs hotter. Heat is what kills this transmission: GEARS Magazine puts the ideal maximum at 200 degrees F and notes that fluid life is roughly cut in half for every 20 degrees above that. Old fluid also loses the friction properties the computer's adaptive shift learning depends on, so shifts get longer and the clutches slip more on each one. The overdrive clutch is the weak spot here. Its steels are very thin and distort when they get hot, so fresh, cool fluid is cheap protection for the most failure-prone pack in the unit.
A fluid service fixes fluid problems. It will not fix a slipping clutch pack or a sticking valve. Pull the dipstick with the engine running and the fluid hot, and look at color and smell. Read codes and watch transmission temperature on a scan tool during a pull. If there are ratio or pressure codes, or fluid is full of metal, diagnose first with our 68RFE Ram 2500 Cummins common problems guide. If the truck is a 3500, the 68RFE Ram 3500 problems guide covers the same failures with heavier-tow examples.
This kit is listed for 2011-2023 Ram 2500 and 3500 trucks with the 6.7L Cummins and the 68RFE. It does not fit the Aisin AS68RC or AS69RC used behind the high-output engine in some 3500s. The 68RFE sump filter differs between some 2WD and 4WD trucks, so compare the filter in the photo with the one on your valve body, or send us your year and VIN and we will check before it ships. Everything else we stock for this transmission is on the 68RFE parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is a fluid and filter service kit: ten quarts of full synthetic ATF+4-spec fluid, a sump filter, a spin-on filter, a pan gasket and RTV. For a rebuild seal set look at a gasket and seal overhaul kit instead.
Only if the truck has the 68RFE. High-output 3500s often use the Aisin AS68RC or AS69RC, which takes different filters and fluid. Check the transmission tag or send us your VIN.
No. Use one or the other. Most people choose RTV on a pan that has leaked before, and the gasket on a clean, flat pan.
Less than a full fill, because the converter and cooler lines keep a lot of the old fluid. The factory recall procedure lists about 5 quarts after a pan service, so this kit covers two drain-and-fills.
With the engine running, the shifter in park and the fluid at 160 degrees F or more. Checking cold will read low and lead to overfilling.
It is not required, but if shift quality changed before the service, clearing the adaptives and running the quick learn with a capable scan tool gives the computer a clean start on the new fluid.
