68RFE Solenoid Kit 2007-2018, remanufactured and ready to install. Fits the 68RFE. Ships fast from the USA.
This part is for Ram 2500 and 3500 pickups with the 6.7L Cummins and 68RFE automatic, 2007 through 2018, that tow heavy and have started to shift badly. Common complaints are a flare on the 2-3 or 4-5 shift, a thump into Drive, overdrive dropping out, or the truck going into limp mode on the highway. It is a renewed OEM valve body with the solenoid assembly already installed, tested for pressure control and shift timing before it ships. The store title calls it a solenoid kit, but you receive the complete valve body with the solenoid pack on it, ready to bolt up.
Behind a diesel that makes this much torque at low rpm, the 68RFE has very little margin. It is a clutch-to-clutch six-speed, so each upshift means one clutch draining at the same moment another fills. The solenoid pack on top of the valve body times those events, and five pressure switches in the pack confirm that each circuit came up to pressure. Sonnax gives the switch thresholds as closing at about 22 psi and releasing at about 11 psi. Underneath, the casting holds the regulator, switch valves and accumulators that shape how firm each shift feels. When oil leaks past worn valves, the switches see low pressure, the computer logs a fault, and the clutch that should be holding the load slips and heats up.
Start with the cheap checks: fluid level and condition with the oil hot, the harness at the case connector, and a code scan. A burnt smell with dark fluid means clutch damage has started, and a new valve body alone will not fix it. Next compare desired and actual line pressure. Gears Magazine reports healthy 68RFE idle pressure in the 60 to 70 psi range, with commanded and actual close together. Our Ram 2500 Cummins 68RFE problems guide lists the common failures in towing trucks, and the 68RFE speed sensor guide explains how a bad input or output sensor can mimic a hydraulic fault, which is worth ruling out before you spend on hydraulics.
The listing covers 2007-2018 Ram 2500 and 3500 trucks with the 6.7L Cummins and the 68RFE, a span that includes more than one solenoid design. Early trucks used a white-connector pack with an overdrive solenoid. Around 2010 running changes removed that solenoid and moved to a gray connector. Sonnax confirms that 2019 and later trucks changed again, to a blue connector and a separate converter clutch solenoid, so this unit does not fit 2019-up. Because the body and pack ship together, they are matched to each other. Make sure the assembly also matches your truck's era: check the connector color on your old pack, or send your year and VIN before ordering. If you only need the casting, compare the 68RFE valve body for 2007-2018. The full range is in the 68RFE collection.
Plan for a pan drop, filter, manual lever and connector removal, and a clean work area for the swap. If you are going to keep towing, this is a good time to add the 68RFE aluminum deep pan with filter kit. Extra fluid capacity helps the 68RFE run cooler. Refill only with ATF+4 and check the level at operating temperature, then clear codes and run the quick learn so clutch fill timing is reset for the renewed body. If the old fluid showed heavy friction debris, put a BorgWarner 68RFE friction clutch module kit into the rebuild at the same time, because a fresh valve body cannot recover a glazed clutch pack.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. It is a renewed OEM valve body with the solenoid assembly installed, so the pack and casting ship together and are tested as one unit.
No. 2019 and later 68RFE trucks use a blue-connector design with a separate converter clutch solenoid. This assembly covers 2007-2018 trucks only.
Both years are within the listing range, but the solenoid design changed around 2010. Send us your year and VIN before ordering so the assembly can be matched to your truck's design.
It fixes slipping caused by low apply pressure from worn valves or a failing pack. If the clutches are already burnt, they need replacing too, so check the fluid and the pan for friction material first.
Yes. Clear codes and run the quick learn with a scan tool after refilling with ATF+4 at operating temperature, so the computer adapts clutch fill to the renewed unit.
