545RFE Input Drum 1999, used and ready to install. Fits the 545RFE. Ships fast from the USA.
Engine runs, the converter turns, but the truck will not move in any gear? On a 45RFE or 545RFE behind the 4.7L V8 in a Ram 1500, Dakota, Durango or Grand Cherokee, a stripped or damaged input shaft is one of the things to check. This page is filed as a 1999 input drum, but the part is actually a used Chrysler input shaft, reference number 4799537, listed with the later Chrysler number 5114582AA and described for 45RFE and 545RFE units from 1999 on with the 4.7L. The photo shows the bare shaft with its splines and sealing ring grooves, not a drum.
The input shaft is the link between the torque converter and the gearbox. Its front splines engage the converter turbine, and the rear of the shaft drives the input clutch retainer that carries the underdrive, overdrive and reverse clutches. Every gear starts here, so a shaft with worn splines can slip or let go entirely regardless of what the clutches are doing. The machined lands and ring grooves along the shaft also seal oil circuits at the front of the transmission. When those lands wear, pressure bleeds off and the problem can look like a hydraulic fault rather than a broken part.
A no-move complaint has several causes. Check the fluid level first, then line pressure, because a failed pump or a stuck pressure control circuit also leaves the truck sitting still. Our 45RFE pump failure guide covers the pump checks. A scan tool that shows input speed matching engine speed while the output stays at zero helps separate a mechanical break from a pressure loss; the speed sensor guide explains how to read those values. The final confirmation is visual: pull the converter and inspect the turbine splines and the shaft.
The listing describes this shaft for 1999-and-later 45RFE and 545RFE transmissions behind the 4.7L. The Mopar parts catalog lists 4799537 as the input shaft for the multi-speed 45RFE in 2001-2004 vehicles, and Chrysler later used 5114582AA. Because RFE units were built behind several engines and the catalogs disagree on years, lay your old shaft beside this one and compare overall length, spline count at both ends and the number and position of ring grooves before installing. If you are not sure, send us your year, model, engine and VIN. Related parts are on the 45RFE and 545RFE collection page.
The 45RFE master rebuild kit for 1999-05 covers the seals and clutches for an early unit, and if the pump bushing is worn the 545RFE pump for 1999-2005 fits the same era.

No. Despite the listing title, it is the input shaft, reference 4799537, listed with the later Chrysler number 5114582AA. The input clutch retainer is sold separately.
The listing describes it for 1999-and-later 45RFE and 545RFE units with the 4.7L. Mopar lists 4799537 for 2001-2004 45RFE vehicles, so compare it with your old shaft before installing.
Typical signs are no movement in any gear with the engine running and normal fluid level, plus rounded splines at the converter or retainer once it is apart. Rule out the pump and line pressure first.
New sealing rings, the converter and retainer splines, the pump bushing and the reaction shaft support. A worn converter will damage the new shaft.
Chrysler specifies 0.46-0.89 mm input shaft end play. Fill with ATF+4 only and run the Quick Learn afterwards.
