545RFE Valve Body 2007-2018, remanufactured and ready to install. Fits the 545RFE. Ships fast from the USA.
When a 545RFE-equipped Dodge, Ram or Jeep from 2007 onward starts slamming into second, slipping into fifth, hunting between gears with no code at all, or locks itself in limp mode with a line pressure or pressure switch fault, the valve body is the first assembly most transmission shops look at. This remanufactured 545RFE valve body spans the later production years, 2007 through 2018, and replaces a worn casting with a bench-ready unit so you are not rebuilding bores one valve at a time.
The 545RFE is the five-speed member of the RFE family, built off the 45RFE with the same clutch-to-clutch layout. Shifting is done entirely by the valve body: the TCM pulses the solenoid pack, and the bores below it direct oil to the underdrive, overdrive, reverse, 2-4 and low/reverse clutches. Line pressure is not set by a throttle cable. A variable-force pressure control solenoid works against the regulator valve, and a line pressure sensor reports the result so the TCM can correct it in closed loop. That design is precise when the casting is tight, but once the regulator, solenoid switch valve or low/reverse switch valve bores wear, the TCM chases a pressure it can no longer hold, and shift quality falls apart.
Start with the electrical side so you do not buy a casting to fix a wiring fault. Measure the pressure control solenoid at roughly 3.5 ohms and the shift solenoids at roughly 1.3 ohms through the transmission connector. Then put a calibrated gauge on one of the two external line pressure ports and compare it with the sensor reading on a scan tool; the factory test expects them to agree within about 10 psi. A good sensor and good solenoids with pressure that will not hold, or a pressure switch code that follows a single clutch circuit, means the valve body is leaking. Our 45RFE / 545RFE valve body testing guide covers the vacuum test points for each critical bore, and the shift solenoid symptoms guide shows how to separate a solenoid pack failure from casting wear.
This unit is listed for the 545RFE in 2007-2018 applications. The 545RFE went into several Chrysler, Dodge, Ram and Jeep V8 trucks and SUVs in those years, and which vehicles used it depends on the engine and model year, so check the transmission tag on the driver side of the case to confirm you have a 545RFE and not a 45RFE or 65RFE. There was also a hydraulic running change inside this window: our catalog lists separate up-to-2009 seven-ball 545RFE valve bodies, so count the check balls in your old separator plate and compare the casting with the photos. If in doubt, send your year and VIN before ordering. All versions are in the 45RFE/545RFE collection.
Drop the pan, remove the filter, unplug the solenoid pack and lift out the old body, taking care not to lose the check balls if your unit uses loose ones. Clean the pan and magnet, install a fresh RFE filter kit, and torque the valve body and solenoid bolts in sequence to factory spec. Refill with ATF+4 only and check the level hot. Finish with the quick learn procedure on a scan tool; RFE units adapt shift timing continuously, and stale learned values from the worn body will make the new one feel harsh until they are reset. If your solenoid pack tested marginal, replace it now with the 45RFE/545RFE solenoid kit rather than pulling the pan twice.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Read the identification tag on the transmission case. The 545RFE is the five-speed version and the 45RFE is the four-speed. Valve bodies are not interchangeable between them, so confirm before ordering.
Yes. Wear at the solenoid switch valve and low/reverse switch valve bores is a known cause of no reverse or an engine stall when shifting into reverse on RFE transmissions.
Only if it tests bad. Check the pressure control solenoid at about 3.5 ohms and the shift solenoids at about 1.3 ohms. A marginal pack is worth replacing while the pan is already off.
ATF+4. Fill to the hot mark after installation and recheck once the transmission reaches operating temperature.
Yes. Run the quick learn with a capable scan tool so the TCM resets learned clutch values for the new valve body. Without it shifts can stay harsh or soft until it adapts on its own.
