45RFE Valve Body 2009, remanufactured and ready to install. Fits the 45RFE. Ships fast from the USA.
If a 2009 Dodge Ram 1500, Durango, Dakota or Jeep Grand Cherokee, Commander or Liberty with the 45RFE automatic takes a beat too long to engage after you shift into drive, shifts harshly, or has a stored pressure or solenoid code, the valve body is the most likely place that trail leads. This is a remanufactured OEM valve body built specifically for the 2009 model year, backed by a 1-year warranty, so you install a bench-tested known-good part instead of chasing the failure piece by piece on a worn original.
The 45RFE is a clutch-to-clutch automatic with no mechanical fail-safe, so the valve body is doing all the work of getting fluid to the right clutch at the right pressure at the right moment. It carries the pressure control solenoid and shift solenoids that the TCM fires, and it houses the bores those solenoids act on. On a 2009 unit specifically, years of heat cycling and fluid wear are enough to open up clearance in those bores, and once that clearance exists the solenoids can no longer hold the pressure the computer is commanding.
Delayed engagement in particular has more than one possible cause on this family, and swapping the valve body before narrowing it down can mean paying for a part you did not need. Our 45RFE delayed engagement guide walks through separating a worn valve body from a low fluid level, a bad filter or an accumulator piston issue. If the complaint is a stored line-pressure code instead, our 45RFE pressure control solenoid guide covers the P0868/P0869/P0932 family of codes and how to tell a bad solenoid from a worn valve body bore.
This valve body is built for the 45RFE as installed in the 2009 model year across the Dodge Ram 1500, Durango, Dakota and Jeep Grand Cherokee, Commander and Liberty lineup. The 45RFE and 545RFE share a casting family but are not identical across every year of production, so confirm the part is being matched against a 2009 application and not assumed to cross over to an earlier or later year without checking. If your vehicle falls outside 2009, see our 45RFE/545RFE parts hub for the listing that matches your exact year.
Service the fluid and filter at the same time as the valve body - ATF+4 is the correct spec for this transmission, and running the wrong fluid will reproduce the same delayed-engagement and harsh-shift complaints this part is meant to fix. Torque the bolts to factory sequence and spec rather than corner to corner, since uneven clamping can bind a bore that checked out fine before installation. Once it is in, clear the stored codes and run the TCM's adaptive relearn rather than driving the truck normally; this family relies on adaptive pressure learning, and a skipped relearn is a common reason a good valve body still shifts poorly. If the accumulator pistons haven't been addressed, a billet accumulator piston kit installed at the same time resolves a related cause of soft or flared shifts. For a transmission that needs more than the valve body, our 45RFE/545RFE/65RFE master rebuild kit covers the rest of the internals.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is built specifically for the 2009 model year 45RFE. The 45RFE and 545RFE share a casting family but were revised across their production run, so confirm your exact year before ordering rather than assuming cross-year compatibility.
Delayed engagement is one of the symptoms a worn valve body causes, but it can also come from low fluid, a clogged filter or a worn accumulator piston. Our 45RFE delayed engagement guide walks through telling those apart before you replace the valve body.
ATF+4. Running a different fluid spec reproduces the same delayed-engagement and harsh-shift symptoms this valve body is meant to fix.
It is a remanufactured OEM valve body backed by a 1-year warranty.
Clear the stored codes and run the TCM's adaptive relearn drive cycle. This family depends on adaptive pressure learning, and skipping the relearn is a common reason a correctly installed valve body still shifts poorly.
Service the fluid and filter at the same time, and if soft or flared shifts were part of the original complaint, inspect the accumulator pistons - that is a related but separate repair from the valve body itself.
