68RFE Pump 1999-2018, new and ready to install. Fits the 68RFE. Ships fast from the USA.
When an RFE transmission has erratic line pressure, a converter clutch that will not lock or slips, or stalls the engine when you drop it into gear, the problem is often a worn valve in the front pump rather than the pump gears. This listing is a pump valve repair kit, not a complete pump. It contains the four valves that live in the pump: the pressure regulator valve, the TCC switch valve, the TCC regulator valve and the torque converter limit valve. The kit is for all 1999-2018 RFE applications, which covers the 45RFE and 545RFE, the 65RFE and 66RFE, and 2007-2018 68RFE units in Ram 2500 and 3500 Cummins trucks.
The pump gears make the flow. The valves in the pump decide where it goes. The pressure regulator valve sets line pressure and sends excess flow on to the converter and cooler circuit. The TCC switch valve moves the converter between released and applied. The TCC regulator valve controls apply pressure to the converter clutch during partial apply. The torque converter limit valve limits converter feed pressure while the clutch is released.
Sonnax points out a detail that matters on diesel trucks. On a stock RFE the TCC regulator only regulates during partial apply. At full lockup, converter apply pressure equals line pressure, about 160 psi in the forward ranges. Each of these valves runs in an aluminum bore, and as the spool and bore wear, fluid leaks past the valve to exhaust instead of doing its job.
These match the symptom chart Sonnax publishes for the RFE pump valve circuits. Many of them overlap with converter or solenoid faults, so test before you buy.
Start with fluid level at temperature and a pressure check on a scan tool. Our 68RFE pump failure guide walks through commanded versus actual line pressure and which direction points to supply problems. For lockup complaints, rule out the solenoid side using our 68RFE shift solenoid testing guide. With the pump on the bench, vacuum-test the valve bores. A bore that will not hold vacuum leaks under pressure, and a worn bore may need an oversized valve and reaming instead of a stock replacement.
The kit is listed for every 1999-2018 RFE application. It does not fit 2019-and-later units. In 2019 Chrysler moved converter control to a separate TCC solenoid and changed the TCC regulator valve. Those trucks are identified by a blue pass-through case connector and need the 2019-up RFE pump valve kit. If your connector is white or gray, this is the right kit. When in doubt, send us your year and VIN. More parts for these trucks are on our 68RFE parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is a pump valve repair kit with four valves: pressure regulator, TCC switch, TCC regulator and torque converter limit. Your pump body, gears and cover are reused.
No. This kit covers 1999-2018 RFE units. The 2019 redesign changed the converter control circuit and the TCC regulator valve, so 2019-up trucks with the blue case connector need the 2019-up kit.
The listing covers all 1999-2018 RFE applications: 45RFE, 545RFE, 65RFE, 66RFE and 68RFE through 2018.
Yes. Sonnax documents leakage past the OE TCC regulator valve to exhaust in these units, causing no lockup, TCC slip, overheating and TCC codes. Confirm the solenoid and wiring are good before you blame the valve.
A stock valve drops into a bore that is still in spec. A worn bore that fails a vacuum test may need an oversized valve and reaming tools instead, which is shop-level work.
Mopar ATF+4 (MS-9602-F). Prime the pump and set the level with the fluid at 160 degrees F or more.
