47RE Clutch Module 1994-02, new and ready to install. Fits the 47RE. Ships fast from the USA.
A 47RE behind a 5.9L Cummins or 8.0L V10 that has cooked its overdrive or direct clutches while towing usually comes apart with blued, glazed steels as well as burnt frictions. Putting fresh frictions against those old plates is how a rebuild slips again inside a few thousand miles. This listing is a set of Alto Kolene-treated steel clutch plates, Alto part 028753EHP (also listed as 028755), taken from Alto's Extreme Performance A518/A618 kit 028750EHPPWR and listed for 1994-2002 units. It is a steel set only: no friction discs, seals or drum.
Each clutch pack in the A618 is a stack of lined friction discs splined to one member and plain steel plates splined to the other. When the piston clamps the stack, the two lock up, and the steels absorb most of the heat that every shift and every slip generates. On a diesel Ram that heat load is high: the overdrive unit carries full Cummins torque, and Sonnax notes that Chrysler raises line pressure 10-15 psi in fourth on the 46/47RE specifically to add clamping force on the overdrive clutch. When a steel overheats it warps or glazes, and a warped plate drags in some gears and slips in others.
Per the product description, the set contains seven 0.068 in. (1.72 mm) steels for the front and rear clutches, five for the overdrive brake clutch and eight for the overdrive direct pack. Kolene is a salt-bath nitriding treatment that hardens the surface for wear and fatigue resistance, which is what you want on a truck that tows.
Road test and note exactly which ranges slip, then match that against the clutch and band application chart in the factory manual. Check line pressure before opening the case, because a worn pump or valve body that bleeds pressure is often what burned the packs. Our 47RE 3-4 clutch failure guide covers the overdrive tests, and 47RE Ram 2500 Cummins problems covers the towing failures. At teardown, lay each steel on a flat surface; any that rock or show heat color should be replaced as a set.
This set is listed for the A518/46RE and A618/47RE from 1994 through 2002, which on the heavy-duty side means Ram 2500 and 3500 trucks with the 5.9L Cummins or 8.0L V10. Earlier trucks in that range may carry the hydraulic-governor 47RH, which shares the clutch hardware layout. The important check is plate count. The factory manual lists 4 front, 5 overdrive and 10 overdrive direct friction discs for the 47RE, against 8 direct frictions in the 46RE, and Alto built these steels around its own higher-capacity PowerPack layout. Count and measure your old steels, and make sure the steel count works with the frictions you are installing. Send us your year, engine and VIN if you want us to check. Everything for this unit is on our 47RE transmission page.

No. It is Kolene-treated steel plates only, from Alto's 028750EHPPWR kit. Order frictions and seals separately, or use a banner or master rebuild kit for those.
They are listed for 1994-2002 46RE and 47RE units. The factory 47RE direct pack uses 10 friction discs and Alto designed this set around its own capacity layout, so count your old steels and send us your year, engine and VIN if you are not sure.
Steels absorb the heat of a slip. Once they are blued, glazed or warped, new frictions run against them will drag or slip and burn again.
Heavy towing in fourth, low line pressure from a worn pump or valve body, and a weak overdrive direct spring. Check pressures and the spring during the rebuild, not just the plates.
ATF+4. Soak the frictions in it before assembly and check the level hot in Neutral after the rebuild.
