545RFE Pump 2009-2011, used and ready to install. Fits the 545RFE. Ships fast from the USA.
Your 2009-2011 545RFE may sit in gear without moving for a few seconds after a cold start. It may need throttle before it creeps once hot, or store P0868 or P0944. Those faults all trace back to oil supply, and once the filter, fluid and cooler return filter check out, the front pump is next. This is a used 545RFE pump assembly with the front seal, listed for 2009-2011. It suits a builder or shop that wants an OE casting from the right production era at a lower price than a remanufactured unit.
The pump bolts to the front of the case and the converter hub drives its gears at engine speed. The gears draw fluid through the primary filter, and the pressure regulator valve in the pump body sets main line pressure from that flow. That oil feeds the valve body and solenoid pack for clutch apply, the converter, the cooler and the lube circuit. On the RFE design the pump body also holds the converter clutch regulator and switch valves. That is why Sonnax lists TCC slip and TCC codes alongside low pressure as signs of pump wear. The controller reads a line pressure sensor and trims a variable force solenoid to hit its target. A pump that leaks internally leaves the controller asking for pressure the pump cannot make, and that is what sets the pressure codes.
Several cheap faults set the same codes, so check them first. Chrysler's P0944 procedure starts with fluid level, then the pan for debris. Next is the primary filter and its seal, which can stay on the filter neck instead of seating in the pump bore. Last is a loose cooler return filter. With those ruled out, watch desired versus actual line pressure on a scan tool from cold to fully hot. A pump that keeps up cold and falls behind hot is the usual wear pattern. If you see P0934 or P0935, test the pressure sensor and wiring before you blame the pump. Our RFE pump failure guide covers the test order, and the pressure control solenoid and sensor guide covers the electrical side.
This pump is listed for 2009-2011 545RFE transmissions. That is the five-speed RFE behind the V8 engines in 2009-2011 Ram 1500 trucks and the Chrysler and Jeep SUVs of that era. 2009 was a change point for this family. Sonnax groups 2009-later 545RFE parts with the 65RFE and 66RFE rather than with earlier units, and the solenoid pack connector turned gray from 2009. Pumps from earlier years differ in casting and lube passage details, and some replacement pumps come without a front seal. Match your old pump's casting to the photo before installing, or send us your year and VIN to check. All of our parts for this family are on the 45RFE/545RFE collection page, and we list an earlier 2007 545RFE pump separately.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Do not assume it will. 2009 was a change point for this family, and pump castings and lube passages changed over the years. Compare your old pump to the photo, or send us your VIN. We carry separate pumps for earlier 545RFE years.
Yes, this used pump is listed with the seal. Check that the seal is seated straight before installation, and replace it if the converter hub shows grooving.
P0868 (line pressure low) and P0944 (loss of hydraulic pump prime) are the usual ones. Rule out fluid level, the primary filter and its seal, and the cooler return filter first, since they set the same codes.
Use Mopar ATF+4 only. Chrysler lists a 5.2 L service fill for a 4x2, 6.2 L for a 4x4, and 14-16 L after an overhaul. Set the final level with the fluid hot.
Yes. Pour fluid into the pump before assembly, and fill the transmission before the first start so the gears do not run dry.
