68RFE Shift Kit 2007, remanufactured and ready to install. Fits the 68RFE. Ships fast from the USA.
Owners of a 2007.5 and later Ram 2500 or 3500 with the 6.7L Cummins usually land here after the truck starts shifting hard when cold, slipping on the 3-4 or 4-5 under a load, or setting pressure switch codes that come and go. This is a remanufactured original-equipment 68RFE valve body, cleaned, inspected and tested before it leaves. The store lists it as a shift kit, which is wrong: it is a complete factory valve body, shown in the photos with the solenoid and pressure switch assembly mounted, and it ships as pictured.
The 68RFE is a six-speed with clutch-to-clutch shifts, so the valve body is where every shift actually happens. The computer commands solenoids, the solenoids feed oil into the casting, and the casting's valves route it to the underdrive, overdrive, reverse, 2-4 and low/reverse clutches. The solenoid switch valve is the busy one on this unit: it shuttles oil between the low/reverse clutch at low speed and the converter clutch once the truck is moving. Sonnax lists leakage at the switch valve plugs among the main causes of overdrive clutch failure, because lost OD apply oil means a clutch that slips, overheats, and warps. With a diesel pulling a trailer, that slip happens fast.
Start with the basics: hot fluid level, the condition of the fluid, and the case connector. Read live line pressure; a healthy unit at idle runs roughly 60-70 psi with commanded and actual close together, and a wide split means oil is escaping somewhere. Look at the clutch volume index numbers on a capable scan tool to see which clutch is taking too long to fill. Our 68RFE valve body testing guide has the full sequence, and the 68RFE won't shift into overdrive guide separates a real failure from normal shift strategy.
This unit is listed for 2007-up Ram 2500 and 3500 trucks with the 6.7L Cummins and the 68RFE. The 68RFE changed several times inside that span. Early trucks used a white-connector solenoid pack that still carried an overdrive solenoid, later trucks moved to a gray connector, and 2019-up trucks use a blue connector with a separate reverse clutch solenoid. Check ball layouts also differ between early and late castings. Lay your old unit beside the photos and compare the casting, check balls, solenoid configuration and connector before ordering, or send your year and VIN and we will verify it. Other options, including our heavy duty 7-ball 68RFE valve body for up to 2009, are on the 68RFE parts page.
Swap it with the transmission cool and the pan drained. Keep the manual valve lined up with the selector lever as it goes in and tighten the bolts in steps to spec. If you move the solenoid block over from your old unit, use new seals and torque it to 53 in-lb; a fresh 68RFE solenoid block with filter kit is worth it if your block is the original. Refill with ATF+4 only and set the level hot. Finish with the Quick Learn and a road test so the adaptives relearn clutch fill times. A deeper pan adds capacity for towing.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. Despite the store title, it is a remanufactured complete OEM 68RFE valve body, cleaned, inspected and tested, shipped as shown in the photos.
It is listed for 2007-up Ram 2500 and 3500 with the 6.7L Cummins and 68RFE. Designs changed over the years, so match your casting and connector or send your VIN first.
It is pictured with the solenoid and pressure switch assembly mounted and ships as pictured. Compare the photos to your unit, and ask us before ordering if you need a specific connector color.
It can stop the leak that caused it, such as solenoid switch valve bore wear. If the overdrive clutches are already burnt, they need replacing too.
Yes. Run the Quick Learn with a capable scan tool and then drive the truck so the adaptives settle. Use ATF+4 only.
