Complete 545RFE valve body with the solenoid block attached, for Dodge Ram, Dakota, Durango and Jeep 4.7L and 5.7L RFE five-speeds.
A Dodge Ram 1500, 2500 or 3500, Dakota, Durango, Chrysler Aspen, or Jeep Grand Cherokee, Commander or Liberty running the 4.7L or 5.7L RFE five-speed that is stuck in third behind a limp light, has lost 2nd gear, bangs hard into the 1-2 shift, or waits a beat before it grabs Drive after sitting overnight is almost always pointing at the valve body and the solenoid pack bolted to it. This listing is both parts as one remanufactured assembly - the black-connector solenoid block already mounted to the valve body casting - so the job is a single bolt-in instead of sourcing a valve body, a separate solenoid pack, and the gaskets between them one at a time.
On the RFE family the valve body is the hydraulic brain, routing line pressure through its spool valves to apply each clutch and band, while the solenoid pack is what the computer actually commands - it opens and closes the circuits that move those spool valves and sets line pressure itself. The two parts share one gasket interface and wear on the same schedule: bore wear in the casting and a tired solenoid switch valve both show up as the identical symptom, loss of drive after a shift into Reverse, which is why replacing them as a matched pair is the fix that actually holds instead of bolting a fresh solenoid pack onto a worn casting.
Pull codes and note whether the fault is constant or only shows up cold, then read the connector color on the solenoid block already in the truck - Chrysler ran this family with more than one pack design, and matching yours avoids installing an assembly whose connector plug does not match your harness. Our 45RFE / 545RFE valve body problems and testing guide walks through the vacuum and resistance checks that separate a true hydraulic fault from a wiring issue before you spend on a reman unit, and the Chrysler 45RFE and 545RFE transmission problems guide covers the wider failure list for this platform.
This assembly interchanges across the RFE family - the 45RFE four-speed, 545RFE five-speed, and 68RFE - and covers the Ram 1500/2500/3500, Dakota, Durango, Aspen, and the Jeep Grand Cherokee, Commander and Liberty of the same era behind the 4.7L and 5.7L. Confirm the connector color on the solenoid block in your truck against this listing before ordering, since the black-connector and grey-connector generations are not interchangeable. See the full 45RFE/545RFE parts collection if your truck turns out to need the later generation instead.
This is a pan-down job: drain the fluid, pull the pan and filter, unplug the solenoid block connector at the case, disconnect the manual valve link from the shift lever, and remove the valve body bolts to lower the assembly out. On reassembly, engage the manual valve link first and start every bolt by hand before torquing so the separator plate seats flat against the case. Fill with ATF+4 only - substitute fluid will not hold up in this family - and run the shift adaptive relearn after the first drive. Since you are already in the pan, pair this job with a 45RFE/545RFE/65RFE master rebuild kit so the clutches and seals are fresh at the same mileage as the new valve body, or at minimum a fresh filter and pan gasket so debris from the old unit does not circulate through the replacement.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The two parts share one gasket interface and wear together - a worn valve body bore and a tired solenoid switch valve both produce the same symptom, loss of drive after a shift to Reverse. Replacing them as a matched, pre-assembled pair avoids a comeback from pairing a new solenoid pack with a worn casting.
The RFE family (45RFE, 545RFE and 68RFE) as used behind the 4.7L and 5.7L in the Dodge Ram 1500, 2500 and 3500, Dakota, Durango, Chrysler Aspen, and Jeep Grand Cherokee, Commander and Liberty.
Limp mode stuck in 3rd gear, no 2nd gear, a hard 1-2 shift, delayed engagement into Drive after sitting, and P0700 stored with a P0750-P0765 solenoid circuit code.
Drop the pan and read the connector color on the solenoid block already installed - this assembly uses the black connector. If your truck has the later grey-connector pack, check our 45RFE/545RFE collection for the correct generation.
ATF+4 only. The RFE family does not tolerate substitute fluid, and running the wrong fluid will undo a correct valve body repair.
Yes - run the shift adaptive relearn after the first drive so the TCM re-times clutch fill against the new valve body instead of the worn one it replaced.
