68RFE Governor Pressure Solenoid 2019-2025

On a 2019 to 2025 Ram 2500 or 3500 with the 6.7L Cummins, a truck that suddenly holds one gear, throws pressure switch codes or shifts hard when hot sends a lot of owners looking for a 68RFE governor pressure solenoid. There is no such part on this transmission. What controls the shifts is the solenoid pack on the valve body, and this listing is the late version of it: a remanufactured Mopar pack, part number 68456067AA, identified by the blue pass-through connector that only the 2019-and-later 68RFE uses.

How the blue-connector pack works in a 2019-up 68RFE

The controller energizes solenoids on this pack to apply each clutch, uses the variable force solenoid to set line pressure, and reads the pack's pressure switches to confirm each circuit actually filled. For 2019, Chrysler reworked the hydraulics. Transmission Digest describes two changes that matter when you buy this part. First, torque converter clutch control moved to a separate small solenoid housing on the lower channel plate, so the low/reverse solenoid no longer doubles as the TCC solenoid. Second, the pack gained a normally applied Reverse clutch solenoid in the spot where the old overdrive solenoid sat. That is why the blue pack and the earlier white and gray packs are not interchangeable in either direction.

Symptoms that lead back to the pack

• Limp mode with solenoid or pressure switch codes that come back after clearing
• P0868 or P0869 line pressure codes with soft or harsh engagements
• Shift timing that wanders once the fluid is fully hot, especially under a trailer
• A bind-up the moment you release the brake in Drive after the pack was serviced, which points to the wrong block gasket
• Erratic shifting that changes when the connector at the case is wiggled

Converter lockup complaints alone do not condemn this pack on a 2019-up truck, because the TCC solenoid is now a separate part.

Rule out the look-alikes first

Late 68RFE trucks have a few known problems that can mimic a pack failure. FCA Safety Recall W03 covered the valve body on 2019 and 2020 Ram 2500 and 3500 trucks, so check open recalls by VIN before buying anything. For 2024 trucks built in a mid-2024 window, an FCA service bulletin addresses a cracking rear selective thrust washer that sets its own codes. Beyond that, compare desired and actual line pressure on a scan tool and read the pressure switch states in each gear. Sonnax explains that an open pressure control circuit drives line pressure to maximum, which is a pack or wiring fault, while low or unstable pressure is more often pump or valve body leakage. Our 68RFE solenoid testing guide covers the electrical checks, and the 68RFE speed sensor guide explains why a sensor fault can look like a shifting problem.

Fitment

This pack is listed for 2019 through 2025 68RFE transmissions in Ram 2500, 3500 and cab-chassis trucks with the 6.7L Cummins, matched to Mopar part number 68456067AA. The quickest check is the connector on the pack you are replacing: it must be blue. A white or gray connector means an earlier transmission that needs a different pack and gasket. Compare the part number on your old pack if it is readable, and if anything is unclear send us your year and VIN and we will confirm before it ships. The rest of our late-model parts are on the 68RFE parts page.

Install notes

• Drain the fluid, drop the pan and sump filter, and unplug the case connector before removing the pack bolts.
• Use only the blue-pack block gasket. Transmission Digest shows the earlier gasket feeds line pressure to the Reverse solenoid in Drive and binds the transmission.
• Inspect the connector seals and pins for fluid intrusion or heat damage.
• Refill with ATF+4. The FCA recall instructions call for checking the level only once the fluid reaches at least 160 degrees F.
• Clear codes and run the quick learn with a scan tool, then road test with a gradual warm-up.

If the truck has high mileage or a history of slipping, the 2019-2022 blue connector overhaul kit and a 68RFE friction module are worth pricing at the same time, since a new pack cannot fix worn clutches.

Does the 2019-2025 68RFE have a governor pressure solenoid?

No. Shifts and line pressure are handled by the solenoid pack on the valve body, which is this part. Governor pressure solenoids were used on the older RE four-speed transmissions.

How do I know my truck takes the blue-connector pack?

Look at the pass-through connector on your current pack with the pan off. Blue means this pack fits. White or gray connectors belong to 2007-2018 transmissions and need a different pack and gasket.

Will this fix a torque converter lockup problem?

Not by itself. On 2019-up trucks the TCC solenoid is a separate unit on the lower channel plate, so test that circuit before replacing the pack.

Is there a recall I should check first?

Yes. FCA Safety Recall W03 covers the valve body on 2019-2020 Ram 2500/3500 trucks with the 68RFE. Run your VIN for open recalls before buying parts.

What fluid and relearn does it need?

ATF+4, with the level set hot. Clear codes and run the quick learn with a scan tool after installation so shift quality is restored.
