47RE Clutch Module 1990, new and ready to install. Fits the 47RE. Ships fast from the USA.
Early heavy-duty Dodge Ram 2500 and 3500 trucks with the Cummins diesel or the V10 used the A618, first as the hydraulic-governor 47RH and from the mid-1990s as the electronic 47RE. When one of these slips while pulling, bangs into gear late, or comes back from a fluid change with black, burnt ATF, the frictions are the first suspect. This listing is a new Exedy EFK153 friction module, titled for 1990 and described for the A518/46RH, 46RE, A618/47RH and 47RE from 1990 on. Exedy packs the lined discs for the main case and overdrive unit clutches in one sealed bag. It does not include steel plates, seals or gaskets.
The A618 shares its layout with the lighter A518: a TorqueFlite-style three-speed main section, then an add-on overdrive unit. In the main section the rear clutch drives the input in all forward gears and the front clutch adds a second input for third, fourth and Reverse. Behind it, the overdrive direct clutch is spring-applied to lock the unit 1:1 until the overdrive piston strokes for fourth. What separates the A618 from the A518 is capacity. The factory manual lists 4 front discs where the 46RE has 3, 5 overdrive discs instead of 4, and 10 overdrive direct discs instead of 8, all to hold diesel torque.
Begin with the level and condition of the fluid, because a low level alone causes slip. Then drive the truck in each range and record where it slips; the clutch and band chart turns that into one or two suspect packs. Low pump output wears out new frictions in short order, so check pressures first. Our 47RE common problems guide lays out the tests in order, and the 47RE pump failure guide explains why a tired pump shows up as slip when the fluid is hot.
The listing is titled for 1990 and the module is described for the whole A518/A618 family from 1990 on, so it is aimed at both 46-series and 47-series units. That is the important point for a heavy-duty owner: a 47RH or 47RE uses more discs in the front, overdrive and direct packs than a 46RE, so check that the set covers your stack before you begin. Lay the old frictions out by pack, compare count, tooth style and lining thickness, and keep them until the rebuild is done. The earliest trucks in this range were hydraulic-governor units, which share the clutch layout but not the electronic governor parts. If you are unsure which unit you have, send us the year, engine and VIN. Browse every A618 part on our 47RE transmission page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is described for the A518 and A618 families from 1990 on. The 47RE uses 4 front, 5 overdrive and 10 direct discs per the factory manual, more than a 46RE, so count your old frictions by pack and confirm before you start. Send us your VIN if unsure.
The clutch packs are the same layout on the 47RH and 47RE, and the module is listed for both. The governor and its parts are different, so this module does not change that.
No. It is friction discs only. Seals and gaskets come in an overhaul kit, and heat-damaged steels should be replaced separately.
Common causes are low pump or line pressure, glazed steels reused with new frictions, a faded overdrive direct spring, and frictions installed without soaking. Check all of these during the rebuild.
ATF+4. Soak the frictions in it before assembly and check the level hot in Neutral after the rebuild.
