545RFE Pump 1999-2007, used and ready to install. Fits the 545RFE. Ships fast from the USA.
If you are rebuilding a 545RFE or 45RFE from a 1999-2007 Jeep Grand Cherokee, Ram 1500, Dakota or Durango and need a straight factory pump instead of paying for a full reman, this is it. It is a good used OEM take-out, inspected before listing, supplied as the pump body with the stator support. It is the seal-type design that went into the 45RFE and the early 545RFE, so it suits a budget rebuild, a core swap after a cracked housing, or a builder who wants to set up the pump with their own valves.
In the 545RFE the pump is the only source of hydraulic pressure. The torque converter hub drives the gears, the stator support carries the converter and feeds oil into the input side of the unit, and the pump body holds the pressure regulator valve and the converter clutch valves. A pump with scored gears, a worn body pocket or a loose regulator valve lets pressure leak away internally, and the transmission responds with slow engagements, slipping and converter clutch complaints.
Chrysler's P0944 procedure is the place to start: it checks fluid level, the primary filter and its seal, and the cooler return filter, and only calls for a pump when the delayed engagement remains and there is no internal seal leak. A loose spacer plate screw on early pumps is another documented cause of low line pressure, so look there if your old pump is still apart. Our 45RFE and 545RFE pump guide explains each check, and the cooler line and flow guide shows how to confirm cooler flow after the pump is in.
This seal-type pump fits 1999-2007 45RFE and early 545RFE units. Typical 45RFE applications include the 1999-2000 Grand Cherokee WJ 4.7L, 2000-2002 Dakota and Durango 4.7L, 2002 Ram 1500 3.7L and 4.7L, and 2002 to early 2003 Liberty 3.7L. The WJ switched to the 545RFE around 2001. Later 545RFE pumps changed seal style and lube circuit casting, so put your old pump next to the listing photos or send us your year and VIN before ordering. A rebuilt option is the 45RFE pump 1999-2007, and the full range is on the 45RFE and 545RFE parts page.

It is a good used OEM take-out, inspected before listing, supplied as the pump body with the stator support. Treat it like a core you will freshen: new front seal, bushing and sealing rings.
Seal-type pumps were used on the 45RFE and early 545RFE. Later 545RFE units changed seal style and casting, so compare your old pump to the photos or send us your VIN before ordering.
Yes. The seal-type pump is shared between the 1999-2007 45RFE and early 545RFE units, such as the 1999-2000 Grand Cherokee WJ 4.7L and 2000-2002 Dakota and Durango 4.7L.
ATF+4 only. Chrysler lists 5.2 L for a 4x2 service, 6.2 L for 4x4, and 14 to 16 L after an overhaul.
Yes. Check gear clearance and gear faces, clean and free up the regulator and TCC valves, confirm the spacer plate screws are tight, and replace the front seal and bushing.
