45RFE Valve Body 1999-2010, remanufactured and ready to install. Fits the 45RFE. Ships fast from the USA.
If your 1999-2010 Dodge Ram, Durango, Dakota or Jeep Grand Cherokee, Commander or Liberty is shifting harsh, flaring between gears, hesitating before it engages, or has thrown you into limp mode with a pressure or solenoid code, the valve body is the part Chrysler's own RFE family fails at most often. This is a remanufactured, bench-ready 45RFE valve body, so instead of chasing a worn bore or a sticking solenoid switch valve piece by piece, you install a complete unit that has already been rebuilt and tested.
The 45RFE is a clutch-to-clutch electronic automatic, which means there is no manual-valve fallback timing shifts - the valve body is the hydraulic brain that routes line pressure through precision bores and spool valves to apply each clutch and band, while carrying the shift and pressure-control solenoids the TCM uses to time every shift. Chrysler's own RFE documentation singles out the solenoid switch valve inside this unit as a recurring wear point, because it is the valve that redirects the 2nd/OD clutch feed into reverse apply, and a worn bore there is what produces the family's signature loss-of-reverse complaint.
Scan for codes before you buy. P0871 (pressure switch rationality), P0868/P0869 (line pressure low/high) and the shift-solenoid codes all point back to this valve body rather than the pump or clutch packs, and the solenoid switch valve wear that causes delayed or lost reverse often sets no code at all. Our 45RFE valve body problems and testing guide walks through the bore and vacuum checks that confirm a hydraulic fault, and if your complaint is specifically a slow or delayed engagement into gear, our delayed-engagement writeup covers the accumulator and check-ball wear that often rides along with a tired valve body.
This listing covers the 45RFE as built from 1999 through 2010 across Dodge Ram 1500, Durango, Dakota and Jeep Grand Cherokee, Commander and Liberty. Chrysler ran this unit through several revisions over that span - our heavy-duty 7-ball version is a documented running change from the original casting - so match your transmission's casting marks and connector count against the photos before ordering, or send us your year and VIN and we will confirm the correct revision for your application. The full 45RFE parts collection has the rest of what we stock for this transmission, including the later-production and 545RFE-specific valve bodies if your unit turns out to be the 5-speed version.
Drop the pan and change the filter at the same time as the valve body swap, so contamination from the failed unit does not circulate into the new one, and refill with ATF+4 only - this transmission does not tolerate a substitute fluid. Torque the valve body bolts in the sequence Chrysler specifies rather than corner to corner, and run the TCM's adaptive relearn after the swap so the computer re-times clutch fill against the new unit instead of the worn one. Because the solenoid pack lives on this valve body, a stored solenoid code or high solenoid resistance reading is worth checking against a fresh 45RFE solenoid kit before you commit to the full assembly, and if your speed sensor readings were unstable going in, pair the install with our input/output speed and pressure sensor kit so you are not chasing a second fault right after the first repair.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It replaces the hydraulic circuit and solenoid pack that control every shift in the 45RFE - a worn one causes harsh or flared shifts, slipping, delayed or lost reverse, torque converter shudder, and limp mode with a solenoid or line-pressure code.
Usually yes. That is the classic symptom of a worn solenoid switch valve bore inside the valve body, the same valve that redirects the 2nd/OD clutch feed into reverse apply. It often sets no code, so a diagnosis by symptom is normal here.
It covers the 45RFE across that span as installed in Ram 1500, Durango, Dakota and the Jeep Grand Cherokee, Commander and Liberty, but Chrysler ran several revisions - including a heavy-duty 7-ball casting - so match casting marks and connector count against the photos or send us your VIN.
ATF+4 only. Change the fluid and filter at the same time as the valve body so debris from the old unit is not carried into the new one.
Yes - clear codes and run the TCM's adaptive relearn so it re-times clutch fill against the new valve body instead of the old, worn one.
Not necessarily. If the hydraulic bores are not worn and the only issue is a failed solenoid or high resistance reading, a solenoid kit paired with fresh fluid can be the cheaper fix.
