48RE Clutch Module, new and ready to install. Fits the 48RE. Ships fast from the USA.
When a Cummins-powered Ram 2500 or 3500 with the 48RE starts slipping on a hill, flares between gears with a trailer behind it, or turns its fluid dark brown, the friction lining is usually what gave up. This is a new Raybestos Clutch-Pack of friction plates for the 48RE, for the rebuilder who has the transmission apart and wants name-brand frictions rather than a mixed bag of unbranded plates.
The 48RE is the last and toughest of the Chrysler RE family, built for the 2003-2007 Cummins trucks. It shares the RE layout of four clutches: rear and front clutches in the main case, and an overdrive clutch and spring-applied direct clutch in the rear overdrive unit, all working with two bands. The engine in front of it, though, makes far more torque than the gas engines the design started life behind. That leaves very little margin. A friction that has lost a fraction of its lining thickness, or has glazed from heat, lets the clutch slip, the slip makes heat, and the heat finishes off the rest of the pack. Fresh frictions with correctly set clearance are the core of any 48RE rebuild that is going to live behind a diesel.
Sonnax notes that a 48RE fitted with the wrong valve body often returns with a failed overdrive clutch, so slipping frictions can be a symptom of a hydraulic problem rather than the root cause.
Confirm the fluid level hot and in Neutral, read any stored codes, and run a line pressure check. Then work out which range slips so you know which pack failed. Our Ram 3500 Cummins shift problems guide lays out the slip patterns, and the 3-4 clutch failure guide covers the overdrive unit, which is the pack that fails most often behind a Cummins.
This listing is for the 48RE without a year range, so it is meant for the 2003-2007 heavy-duty Ram application. The photo shows Raybestos Clutch-Pack friction plates, and the listing does not state which clutch or how many plates are included. Before ordering, count the frictions in the clutch you are rebuilding and compare the tooth style and diameter with the photo, or send us your year and VIN and we will confirm it. You can see every 48RE part we stock on the 48RE collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The photo shows Raybestos Clutch-Pack packaging and plates, and the listing lists Raybestos as the brand.
The listing does not state the clutch position or plate count. Count the frictions in the pack you are rebuilding and compare tooth style and size to the photo, or send us your year and VIN before ordering.
It is listed for the 48RE used in 2003-2007 Ram heavy-duty trucks. Some RE clutch plates interchange across the family, but plate counts differ, so check against your old plates before using it in an older unit.
Replace any steel that is blued, warped or scored. If the old frictions burnt, the steels are usually heat damaged as well.
ATF+4. Chrysler warns that other fluids can cause poor shift quality and torque converter shudder.
