68RFE Solenoid Kit 1999-2018, remanufactured and ready to install. Fits the 68RFE. Ships fast from the USA.
If your Ram 2500 or 3500 with the 6.7L Cummins and 68RFE automatic drops into limp mode on a grade, flares between gears while towing, or sets pressure switch and solenoid codes, the solenoid pack on top of the valve body is one of the first parts to test. This is a remanufactured 68RFE solenoid kit. The product photo shows the solenoid pack together with a pan filter, a spin-on secondary filter and a rubber pan gasket, so the full service can be done with the pan off once. The listing range reads 1999-2018 because the RFE pack bolt pattern goes back to the first 45RFE, but the 68RFE itself only arrived behind the Cummins in 2007, so on a 68RFE truck this kit is for 2007 through 2018.
The 68RFE is a six-speed clutch-to-clutch automatic, which means every shift is one clutch releasing while another applies, with no band or one-way clutch to cover a late handoff. The pack is the part that times those events. It holds the low/reverse, underdrive, second, fourth, overdrive and multi-select solenoids plus the variable line pressure solenoid, and it carries the pressure switches the computer uses to confirm each clutch circuit actually filled. Sonnax describes five pressure switches in the RFE pack that close at about 22 psi and open at about 11 psi. On a 68RFE built before 2019 the low/reverse solenoid also doubles as the converter clutch solenoid, so a weak L/R coil can show up as converter slip codes as well as a harsh first gear.
Check fluid level and condition hot first, then check the case connector for bent pins and oil wicking. With the harness unplugged, measure resistance at the pack from common pin 10. The Sonnax sheet lists about 1.3 ohms for each clutch solenoid and about 4.3 ohms for the line pressure solenoid at room temperature. An open, shorted or out-of-family coil points at the pack. If every coil checks good, compare commanded and actual line pressure before spending money, because a worn pump or valve body can set the same codes. Our 68RFE shift solenoid testing guide walks through the full electrical check, and the Ram 3500 Cummins shift problems guide covers the other causes of the same complaints.
For 68RFE trucks this kit covers 2007-2018. Transmission Digest explains that the 68RFE started with a white-connector pack, dropped the overdrive solenoid on a gray-connector pack around 2010, and changed in 2019 to a blue-connector design with a separate converter clutch solenoid and a new reverse clutch solenoid. That 2019-up design is not covered here; see the 68RFE solenoid kit for 2019 instead. The connector housing on the pack in our photo is dark rather than white or gray, so compare it with your old pack when it arrives. Sonnax notes that a black-connector pack needs the striker plate from your existing valve body, so keep that plate. When in doubt, send us your year and VIN, and browse the 68RFE parts page for other versions.

No 68RFE was built in 1999. The 1999-2018 range reflects the RFE pack design that started with the 45RFE. On a 68RFE Cummins truck, this kit is for 2007 through 2018.
The product photo shows the solenoid pack, a pan filter, a spin-on secondary filter and a pan gasket.
No. 2019-up trucks use a blue-connector pack with a separate converter clutch solenoid and a reverse clutch solenoid, plus a different gasket. Use the 2019 version instead.
About 1.3 ohms for each clutch solenoid and about 4.3 ohms for the line pressure solenoid, measured from common pin 10 at room temperature.
ATF+4. Check the level with the fluid at operating temperature, not cold.
Yes. Clear the codes and run the quick learn, then drive 10 to 15 upshift and downshift cycles so the computer adapts to the new solenoids.
