68RFE Pressure Control Solenoid, new 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 slams into gear, flares between shifts with a trailer behind it, or drops into its third-gear default with a line pressure code stored, the pressure control solenoid is one of the first parts a shop looks at. On the 68RFE that solenoid is not sold as a separate plug-in piece. It is built into the solenoid and pressure switch assembly bolted to the valve body, so the replacement part is the complete pack. This listing is a new Mopar pack.
Chrysler's RFE family runs a closed-loop pressure system. A line pressure sensor threaded into the case reports actual pressure, the controller compares it to a target based on calculated input torque, and the pressure control solenoid (a variable force solenoid, pin 12 on the 23-pin connector) corrects the difference by changing duty cycle. The solenoid works backwards from what most people expect: it bleeds oil against the regulator valve spring to lower pressure. Low duty cycle means high pressure, so an open coil or broken wire leaves the truck at maximum line pressure with hard engagements, while a solenoid stuck on pulls pressure down and lets clutches slip. Sonnax measures the pressure control solenoid at about 3.5 ohms, against roughly 1.3 ohms for each shift solenoid in the same pack. The pack also carries the shift solenoids and five pressure switches that tell the controller whether each clutch actually received oil.
Be careful with P0871. Sonnax traces about 90 percent of those to worn solenoid switch valve bores in the valve body, not to the solenoid pack, so a new pack will not cure it on its own.
Put desired line pressure, actual line pressure and pressure control duty cycle on the scan tool together. GEARS Magazine gives a healthy 68RFE at idle as 60 to 70 psi commanded and actual at roughly 22 to 24 percent duty cycle. If actual tracks desired, the solenoid is doing its job; if the duty cycle has fallen toward the bottom of its range just to hold modest pressure, oil is leaking internally and the pump or valve body is the real problem. Run the key-on, engine-running Reverse test from our 68RFE shift solenoid testing guide as well: in Reverse all five pressure switches should read open. For low-pressure complaints, also read our 68RFE pump failure guide before spending money on electrical parts.
This pack fits the 68RFE six-speed used behind the 6.7L Cummins in 2007-up Ram 2500, 3500, 4500 and 5500 trucks. The listing itself does not carry a year range, and the pack changed twice: white connector packs ran through 2009 with six solenoids, gray connector packs from 2010 dropped the overdrive solenoid, and blue connector packs from 2019 added a reverse clutch solenoid with converter clutch control moved to its own solenoid. The pack in our photo has a blue connector. Match the connector color and part number on your old pack, or send us your year and VIN before ordering. Browse every 68RFE part we carry, including the dedicated 2019-2025 pack listing.
If the valve body bores are already worn, pair the pack with a reworked unit such as the BD Diesel 6.7L valve body, or keep the ATSG 68RFE manual on the bench for the job.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. On the 68RFE the pressure control solenoid is built into the solenoid and pressure switch assembly along with the shift solenoids and pressure switches, so it is serviced as the complete pack.
It is a 68RFE pack for the 6.7L Cummins Ram heavy-duty trucks. Because white, gray and blue connector packs are not all interchangeable, match the connector color and part number on your old pack or send us your year and VIN before ordering.
Usually not by itself. Sonnax links roughly 90 percent of 68RFE P0871 codes to worn solenoid switch valve bores in the valve body. Vacuum test the valve body before buying a pack for that code.
ATF+4 only. Set the level with the fluid at 160 degrees F or hotter, since a cold check on this transmission reads low and leads to overfilling.
Yes. Clear the stored codes and run the quick learn procedure so the controller relearns clutch fill volumes with the new pack. Shift quality can be rough until the adaptives settle.
Yes. The pan is already off, so install a new filter and pan gasket. The 2019-up and earlier packs use different filter screens, so use the one that matches your pack.
