45RFE Clutch Module 1999, new and ready to install. Fits the 45RFE. Ships fast from the USA.
A four-speed 45RFE that slips into third, flares between second and third, or drops into limp mode with a gear ratio code usually has one thing in common when it comes apart: friction plates that have glazed or shed their lining. This listing is the Raybestos RGPZ-105 friction module (cross-referenced as 72119B), a complete set of frictions for every clutch in the 45RFE, sold new. The 1999 in the title is where its coverage starts. Raybestos lists it for 1999-on 45RFE and 545RFE units, the transmission behind the Ram 1500, Dakota, Durango, Grand Cherokee, Commander and Liberty.
The 45RFE was Chrysler's first rear-drive, fully electronic automatic, and it shifts without a single band. Six multi-disc clutches do all of the work: underdrive, overdrive and reverse inside the input clutch housing, and the 2C, 4C and low/reverse clutches applied against the case. The controller builds each gear by clamping a pair of them, for example underdrive with overdrive for third and overdrive with 4C for fourth, and it times every shift by watching input and output speed. When the friction lining wears, the pack cannot hold torque, the speed ratio drifts, and the computer reads that as a slip. In the RGPZ-105 box you get six GPZ710 frictions for the reverse and underdrive clutches, four GPZ140 overdrive plates, three GPZ220 plates for 2C, three GPZ225 plates for 4C and six R559230 high energy low/reverse plates. Raybestos aims the GPZ material at heavy-duty and high-stress use, which suits a truck that tows.
New frictions only last if the reason the old ones burned is fixed in the same job. On the RFE family, overdrive clutch failure traces most often to the solenoid switch valve, a leaking or restricted dribbler circuit in the stator support, or clutch clearance set wrong on the last rebuild. Read the 45RFE 3-4 clutch failure guide for the air checks and those three areas, and use the pressure control solenoid and line pressure guide to compare commanded and actual line pressure on a scan tool. Low pressure from a tired pump will cook a fresh set of plates just as fast as a worn valve body.
The RGPZ-105 covers 45RFE transmissions from 1999 forward and also fits the 545RFE, because both units share the same clutch hardware and differ mainly in programming. That makes it a match for the 1999-2005 four-speed trucks most 45RFE owners drive. Chrysler did change overdrive plate thickness and the underdrive and overdrive pressure plates between the 1999-2006 and 2007-up builds, so count and measure the plates you pull from each drum and check them against the new set before stacking anything. If you are unsure which unit is in your truck, read the transmission tag or send us the year and VIN and we will confirm it. Every other part for this family is on the 45RFE and 545RFE parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is the friction side only: 22 Raybestos frictions covering all six clutches in the 45RFE. Steel plates, seals and pressure plates are not included.
Raybestos lists the RGPZ-105 for 1999-on 45RFE and 545RFE, so a 2003 four-speed is inside that range. Compare plate count and thickness to what you remove before assembly, or send us your VIN and we will check.
On RFE units the usual causes are a worn solenoid switch valve, a leaking or blocked dribbler circuit in the stator support, or clutch clearance set out of spec. Find and fix the cause or the new plates will fail too.
ATF+4 only. Soak the frictions in it before assembly and refill the transmission with it afterward.
Yes. Chrysler calls for the Quick Learn procedure after any clutch plate or seal replacement so the controller relearns clutch fill on the new plates.
