68RFE Governor Pressure Solenoid 2004, remanufactured and ready to install. Fits the 68RFE. Ships fast from the USA.
Owners of a 2007.5 to 2009 Ram 2500 or 3500 with the 6.7L Cummins often search for a 68RFE governor pressure solenoid after the truck gets stuck in a single gear, flares between shifts, or sets a string of solenoid codes. The 68RFE has no governor and no governor pressure solenoid; that part lived on the older RE four-speeds. The part that actually controls shifting and line pressure in this transmission is the solenoid pack, and that is what this listing supplies: a remanufactured Mopar pack, manufacturer part number 52119435AF, with the white pass-through connector. The same white-connector design also serves 2004-and-later 45RFE and 545RFE units in Ram 1500, Dakota, Durango and Jeep applications.
Every shift in an RFE transmission is commanded electronically. The pack bolts to the valve body and carries the shift solenoids, the variable force solenoid that sets line pressure, and the pressure switches that tell the controller whether each clutch circuit really filled. On the early 68RFE the white-connector pack still carries six solenoids, including the overdrive solenoid. Transmission Digest explains that the 68RFE launched with this white-connector design, the same one used in the 45RFE and 545RFE, and that the overdrive solenoid was dropped around 2010 when the gray-connector pack arrived. Because a 6.7L diesel puts far more torque through the clutches than a gas 545RFE, a pack that responds slowly or leaks internally shows up quickly as slip and flare on a loaded truck.
Solenoid codes on an RFE do not automatically mean a bad solenoid. Start with a hot fluid level check and the condition of the ATF+4, then inspect the 23-pin pass-through connector for oil wicking or pushed-back pins. Sonnax publishes resistance specs for these packs, roughly 1.3 ohms for each shift solenoid and 3.5 ohms for the pressure control solenoid, so a meter at the connector separates an open coil from a hydraulic leak. Watch desired versus actual line pressure on a scan tool: an open pressure control circuit drives pressure to maximum, while worn switch valve bores and a warped valve body can upset the pressure switches and set codes that look electrical. Our 68RFE shift solenoid testing guide walks through those checks, and the 68RFE valve body testing guide covers the hydraulic side.
This pack is listed for the 68RFE from its 2007 start, with 2007 to 2012 heavy-duty Ram trucks named in the listing, and for 2004-and-later 45RFE and 545RFE transmissions. Use the connector color as your guide. A white connector is a direct match. Sonnax notes that dealers sometimes used the white pack to service 2009-and-later units when gray packs were back-ordered, but a gray pack can never go back onto an early white-pack valve body, and a 2019-up blue-connector transmission takes a completely different pack. If your truck is a 2010 to 2012 and you see a gray connector when the pan comes off, send us your year and VIN before ordering so we can confirm the match. Everything else for this transmission is on our 68RFE parts page, and gas-engine owners can browse the 545RFE parts page.
If the valve body itself is worn, a pack alone will not cure the codes; the heavy-duty 68RFE valve body for up-to-2009 trucks is the next step for a truck that has seen heavy towing.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The 68RFE, 45RFE and 545RFE have no governor. This is the solenoid pack that bolts to the valve body and controls every shift and line pressure, which is the part people usually need when they search for that name.
A 2007.5 to 2009 68RFE uses the white-connector pack, which is what this is. Confirm the connector on your old pack is white when the pan is off, or send us your year and VIN.
Sonnax notes the white pack was sometimes used to service 2009-and-later units, but the valve body changed when the overdrive solenoid was dropped. Contact us with your VIN before ordering so we can confirm it for your truck.
A new block gasket and filter screens, a sump filter and pan gasket, and fresh ATF+4. If the valve body bores are worn, address the valve body at the same time or the codes may return.
Yes. Clear the codes and run the quick learn with a scan tool so the controller relearns clutch fill times, then expect shifts to settle in over a few drives.
