68RFE Pressure Control Solenoid 2019-2025, remanufactured and ready to install. Fits the 68RFE. Ships fast from the USA.
Owners of 2019 and newer Ram heavy-duty trucks with the 6.7L Cummins and 68RFE usually land here after a line pressure code, a hard engagement, or a shift that flares under a trailer. On this transmission the line pressure control solenoid lives inside the solenoid and pressure switch assembly, so the service part is the complete pack. This listing is a remanufactured late-design pack with the blue 23-pin pass-through connector, the identifier for 2019-up units.
Line pressure in a 68RFE is set electronically. The controller estimates input torque, picks a target pressure, and reads the line pressure sensor to see whether the pump delivered it. The variable force solenoid in the pack, shown as LP VFS control on pin 12 of the Sonnax 2019-later pin chart, makes the adjustment by feeding oil to the end of the pressure regulator valve in the pump. When it is switched off the regulator is left on its spring and line pressure goes to maximum, so a dead coil gives harsh shifts rather than slipping clutches.
The 2019 redesign changed what else sits in the pack. Chrysler put a sixth solenoid back in the old overdrive position, but it now controls a normally applied reverse clutch. Converter clutch control moved out of the pack to a separate solenoid in a new housing on the lower valve body, so the low/reverse solenoid now only applies the low/reverse clutch. Sonnax says these changes were made to improve converter clutch apply and release and to address a clunk when Reverse releases.
Compare desired and actual line pressure on a scan tool, then measure the solenoid at the pack. A flat, unchanging pressure with no current on the control wire points to the solenoid or its wiring; good circuit readings with low pressure point to the pump, regulator or valve body instead. Our 68RFE solenoid testing guide covers the meter work, and the 68RFE P0871 guide explains how the pressure switches on this same pack report a fill problem. A shudder or converter clutch code alone may be the separate converter clutch solenoid, which is not part of this pack.
This pack is listed for the 68RFE from 2019 through 2025. Pull the pan and look at the pass-through connector on your current pack: it should be blue. A gray or white connector means your transmission is the earlier design and this pack will not work in it, because the valve body, gasket and solenoid duties are different. If you have the gray pack, the 68RFE pack for 2010-2018 is the matching part. Not sure which you have? Send your year and VIN and we will check before it ships. All of our 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.
Look at the 23-pin pass-through connector on the pack you are replacing. Blue means the 2019-up design and this part. Gray or white means the earlier design, which uses a different pack and gasket.
No. On 2019-up units the converter clutch solenoid is a separate part mounted in a housing on the lower valve body. If your only complaint is shudder or a converter clutch code, test that solenoid too.
Use a new gasket made for the blue pack. An early-style gasket on this pack lets line pressure reach the reverse clutch solenoid in Drive and causes an immediate bind-up.
ATF+4 with the level set at operating temperature, then clear codes and run the quick learn with a scan tool before driving it hard or towing.
Only if the solenoid or its circuit is the cause. If the coil and circuit test good and pressure is still low, look at the pump pressure regulator bore and the valve body before replacing the pack.
