68RFE Pressure Control Solenoid 2010-2018, remanufactured and ready to install. Fits the 68RFE. Ships fast from the USA.
A 2010 to 2018 Ram heavy-duty with the 6.7L Cummins that suddenly shifts like it was rear-ended, or slips when it is pulling a trailer up a grade, often comes back with P0868 or P0869 on the scan tool. Those are line pressure codes, and the part people go looking for is the 68RFE pressure control solenoid. On this transmission that solenoid is one piece of the solenoid and pressure switch assembly, so the replacement is a complete pack. The pack offered here is the gray-connector design shown in the photo, the version that matches the 2010-2018 years in the listing.
Sonnax reports that by 2010 Chrysler found one of the six solenoids and two valve body check balls were not needed, removed them, and changed the pack connector from white to gray. Transmission Digest identifies the deleted part as the overdrive solenoid. That leaves a five-solenoid pack, and it is why this part cannot go backward: Sonnax states the gray pack cannot service earlier six-solenoid units. It is also why the matching valve body has to be the later design, not just any 68RFE valve body.
Line pressure on the 68RFE is never set by a throttle cable or modulator. The controller works out a target from input torque, commands the variable force solenoid in the pack, and checks the result with a line pressure sensor. GEARS Magazine describes the action: the solenoid sends oil to the end land of the pressure regulator valve in the pump, so raising its duty cycle lowers line pressure and switching it off drives pressure to maximum. Every clutch apply on the truck depends on that number being right.
Start with a hot fluid level and a properly seated filter. Then compare desired and actual line pressure live on a scan tool: if they track each other through park, drive and a loaded upshift, the pressure solenoid is doing its job. If they split, measure the solenoid and its wiring at the pack and verify with a gauge. Good electrical readings with low pressure point to the pump regulator or a worn valve body. Read our 68RFE valve body testing guide before buying, because a worn switch valve bore can look like a solenoid fault and a new pack will not fix it. The Ram 3500 68RFE shift problems guide covers the other common causes.
Listed for the 68RFE, 2010 through 2018. Running changes do not always line up with model years, so confirm by looking at the pass-through connector on your current pack: it should be gray. If yours is white, your transmission is the earlier six-solenoid design and needs the white-connector RFE pack. If it is blue, the truck is a 2019-up unit with a separate converter clutch solenoid and needs the 2019-2025 blue pack. When in doubt, send us the year and VIN. More parts for this unit are on the 68RFE parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Not if your truck still has the white-connector pack. Sonnax notes the gray pack is a five-solenoid design and cannot service the earlier six-solenoid units. Match the connector color or send us your VIN.
No. 2019-up 68RFE units use a blue-connector pack, a different gasket and a separate converter clutch solenoid.
Not always. P0868 means actual line pressure fell more than 10 psi below what the controller wanted. A low fluid level, a loose filter, pump wear or a worn valve body can cause it too. Compare scan data and use a gauge first.
ATF+4. Set the level at operating temperature, then clear codes and run the quick learn.
Use a new white/gray style silicone-beaded gasket. An old or wrong-style gasket can leak pressure between circuits and cause shift faults right after the repair.
