68RFE Pressure Control Solenoid 2010, remanufactured and ready to install. Fits the 68RFE. Ships fast from the USA.
Model year 2010 is the year the 68RFE solenoid pack changed, and that is exactly why a 2010 Ram 2500 or 3500 owner with the 6.7L Cummins needs to be careful when shopping for a pressure control solenoid. If your truck is banging into Drive, flaring on the upshifts while towing, or has stored P0868 or P0869, this is the part that controls line pressure. On the 68RFE it is not a separate plug-in solenoid: the line pressure variable force solenoid is built into the solenoid and pressure switch assembly, so the repair is the complete pack. The unit in this listing is remanufactured and has the gray 23-pin pass-through connector you can see in the photo, with its round connector seal in place.
Sonnax explains that the white-connector pack ran through 2009, and that by then Chrysler had found one of the six solenoids and two valve body check balls were no longer needed. They were removed and the connector turned gray in 2010. Sonnax also notes the overdrive solenoid was dropped with the gray pack around 2009, with the multi-select solenoid taking over its job. Production changes do not respect model years, so a truck built near the switch can carry either design. The rule that matters: a gray five-solenoid pack cannot be installed on an earlier six-solenoid valve body, while Sonnax says the white pack was used to service later units when gray packs were back-ordered.
There is no throttle cable or modulator. The controller calculates a target line pressure, commands the solenoid, and reads the result from a line pressure sensor in the case. GEARS Magazine describes the logic: a high duty cycle sends more oil to the pressure regulator valve and lowers line pressure, a low duty cycle raises it. Every clutch apply, from the bump into Reverse to the 5-6 upshift under a trailer, depends on that loop working.
Check the fluid level hot and make sure the filter is seated. Then watch desired versus actual line pressure on a scan tool through Park, Drive and a loaded upshift. If the line pressure sensor reads below 0.35 volts or above 4.75 volts, GEARS lists P0934 or P0935, which point to the sensor or its wiring, not the solenoid. If the numbers split with good electrical readings, verify with a gauge and inspect the valve body. Our 68RFE valve body testing guide walks through it, and the 68RFE P0871 guide covers the switch valve wear that new packs do not fix.
Listed for the 68RFE in a 2010 Ram heavy-duty. Before ordering, drop the pan or look at the pack connector through the case: if it is gray, this is your part. If it is white, your truck still has the six-solenoid valve body and needs the white-connector RFE pack. If you want the same gray design with a wider year listing, see the 2010-2018 gray pack.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. A white connector means the earlier six-solenoid design, and Sonnax states the gray five-solenoid pack cannot service those units. Order the white-connector pack instead or send us your VIN.
Not on the 68RFE. The line pressure variable force solenoid is part of the solenoid and pressure switch assembly, so the whole pack is replaced.
Probably not. P0934 and P0935 mean the line pressure sensor voltage is out of range, which points to the sensor or its wiring. Check those first.
ATF+4. Check the level hot after the pack is installed, then clear codes and run the quick learn.
Only if testing shows it is needed. A worn solenoid switch valve bore causes pressure switch codes and harsh shifts that a new pack will not cure, so inspect it while the pan is down.
