68RFE Overhaul Kit 2007, new and ready to install. Fits the 68RFE. Ships fast from the USA.
The 2007 model year is where the 68RFE story starts. Chrysler introduced the six-speed that year behind the new 6.7L Cummins in the Ram 2500 and 3500, and the first trucks are now old enough that most original transmissions have either been rebuilt or are due. This kit is the boxed gasket and seal set for that rebuild: the photo shows the valve body separator gaskets, pan gasket, front seal, piston lip seals, sealing rings and O-rings. If your 2007 Ram is slipping in overdrive, weeping fluid from more than one place or slow to pick up Drive on a cold morning, this is the sealing layer you renew while the unit is apart. Clutch frictions and steels are sold separately.
Every gear in the 68RFE comes from applying a clutch pack with oil pressure. There are no bands. Oil leaves the pump, is directed by the solenoid pack and valve body, crosses rotating parts through sealing rings and finally pushes a piston whose lip seals hold that pressure against the pack. The early white-connector design that 2007 trucks use still carries a dedicated overdrive solenoid fed by the D21 line pressure passage through the solenoid block gasket, a part Chrysler later dropped. Once any of the seals along that path harden or take a set, the clutch at the end of it gets less pressure than the controller asked for, and the 68RFE responds the way it always does: flare, slip, heat and a burnt pack.
A single leaking external seal can be replaced on its own, so a kit makes sense when the unit is coming out. Scan for codes, read the fluid, and compare commanded with actual line pressure. Sonnax points out that the 68RFE overdrive clutch uses very thin single-sided steels with a 0.034 inch core and that housing flex and retainer wear contribute to failure, so inspect those parts during the teardown rather than replacing seals alone. Our Ram 3500 Cummins shift problems guide and the 68RFE valve body testing guide walk through separating a hydraulic leak from a mechanical failure.
This listing is for the 2007 68RFE in Ram 2500 and 3500 pickups with the 6.7L Cummins. Those units use the white pass-through connector solenoid assembly with the overdrive solenoid. Transmission Digest notes that the solenoid block gasket for 2019-up blue-connector units blocks the overdrive feed if installed on a white-connector unit and causes a neutral shift into third, so compare the gaskets in the box against your originals before assembly. Overhaul kits for later years, including the 2007-2017 version, are on the 68RFE collection page. Not sure which unit you have? Send us your year and VIN.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The 5.9L trucks used the 48RE four-speed. The 68RFE arrived with the 6.7L Cummins, so check the engine and the transmission tag before ordering.
No. It is the gasket and seal overhaul set. Frictions and steels are purchased separately after the packs are measured.
A white pass-through connector. Gray connectors started with the 2010 valve body changes and blue connectors arrived in 2019.
Common contributors are worn seals and valve body leakage, heat from towing, housing flex and retainer wear. Inspect all of them during the rebuild, not just the seals.
ATF+4 only, with the level set hot at 160 degrees F or above, followed by a TCM quick learn with a capable scan tool.
