45RFE Shift Kit 2009, remanufactured and ready to install. Fits the 45RFE. Ships fast from the USA.
The title says 2009, but this is not a one-year part. It is a remanufactured heavy-duty valve body, number CR-2762HD, built for the 45RFE and 545RFE units that left the factory with the original 7-check-ball valve body, which covers production up to the 2009 model year. If your 1999-2009 Ram 1500, Dakota, Durango, Grand Cherokee, Commander or Liberty flares into Overdrive, slips once the fluid is hot, or keeps setting pressure switch codes, and you would rather bolt in a finished assembly than rebuild the old casting on a bench, this is that option. It comes assembled with gaskets. The solenoid block is not included, so you move yours over or fit a new one.
The 45RFE has no bands and no throttle cable. The solenoid pack on top tells the valve body which clutch to fill, and the casting, separator plate and accumulators decide how quickly and how firmly that clutch actually applies. Pressure switches on the pack report back when each clutch circuit charges; if a switch reading does not match the gear the computer commanded, it stores a code and drops into failsafe. This unit adds a heavy-duty separator plate with gaskets and a heavy-duty accumulator support plate, and it carries an updated solenoid switch valve and plugs. That switch valve shuttles oil between the low/reverse clutch and the converter clutch, and the plugs in its bore help feed the 2nd and Overdrive circuits, so a worn one is behind a long list of RFE complaints from lockup problems to burned clutches.
Chrysler's diagnostic for P0871 lists hydraulic causes in and around the valve body, including check balls 4 and 6, the OD/Reverse piston seal and bleed orifice, and the OD accumulator, alongside the pressure switch itself. That means the electrical side should be cleared first: test the solenoid pack and the harness, then compare commanded and actual line pressure on a scan tool. Our 45RFE pressure control solenoid guide separates pack and line pressure problems from valve body leaks, and 45RFE won't shift into overdrive covers the Overdrive-specific faults. If the pan holds heavy friction material, the clutches need attention before or along with this valve body.
This unit fits 45RFE and 545RFE transmissions with the 7-check-ball valve body, up to 2009. Do not go by the year alone. Count the check balls in your old valve body, and remember Sonnax documents a solenoid switch valve change in this family around 2010, so a 2010-on unit, or an older truck that already received a later replacement valve body, needs a different part. Your solenoid pack must also match your harness: in our catalog the 1999-2003 trucks take a black-connector pack and the 2004-2009 trucks a white-connector pack. Send us your year and VIN and we will confirm the match. Everything we carry for this family is on the 45RFE parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The unit is built for every 7-check-ball 45RFE and 545RFE valve body up to 2009, not only 2009 models. Fitment depends on the 7-ball valve body, so count the check balls or send us your VIN.
No. The solenoid block is not included. Move your old pack over with a new gasket or install a new pack that matches your connector.
No. The switch valve and valve body changed around 2010, so later units need a later valve body.
It has a heavy-duty separator plate with gaskets, a heavy-duty accumulator support plate, and an updated solenoid switch valve and plugs.
Yes. Run the Quick Learn with a scan tool: brakes applied, engine over 500 rpm, throttle under 3 degrees, and fluid between 60 and 200 F.
ATF+4. Install a new filter and pan gasket and check the level with the fluid hot.
