47RE Transmission Master Rebuild Kit with Filter

This kit is built for the heavy-duty side of the Chrysler four-speed family: the 47RE (A618) behind the 5.9L Cummins and the big gas V8s in Ram 2500 and 3500 trucks that tow. When a 47RE starts slipping out of overdrive on a grade, the converter clutch shudders, or the fluid comes out black after a long pull, the clutch packs and seals are done. This TRANSPEED master kit replaces them in one order. It is also listed for the 46RE/A518, and it includes friction plates, steel plates, the gasket set, lip seals, sealing rings, O-rings and a new filter.

What the master kit does in a 47RE

The 47RE uses the same layout as the 46RE, a three-speed with a bolt-on overdrive section, but it was built to take diesel torque, so the clutch packs carry more load and run hotter. Every pack applies through a rubber-sealed piston, and the overdrive and direct clutches sit at the back of the case, where heat from a loaded tow builds up. The seals in this kit are listed as fluororubber (FKM) and ACM compounds rated for high ATF temperature, and the steels are ground flat to match the frictions. Renewing all of them together restores apply pressure throughout the unit instead of leaving one tired ring to leak while new clutches burn up.

Symptoms a 47RE needs this kit

• Overdrive slips or drops out under load, then the engine flares on the 3-4 shift.
• Shudder or slip when the converter clutch applies on the highway.
• Slipping in every gear once the fluid is hot from towing.
• Delayed engagement after sitting, or a long pause into Reverse.
• Black, burnt fluid with lining and metal on the pan magnet.
• Seepage at the front pump seal or the rear seal.

How to confirm it before buying

Cooler restriction is a known trouble spot in the 46/47RE family; Sonnax ties it to converter clutch slip, delayed engagement and noise, and a plugged cooler will cook a fresh rebuild just as fast as the old one. The factory manual also has the transmission refuse overdrive and lockup when fluid temperature runs too high, which can feel like a failure when it is really a heat problem. Check fluid hot, verify cooler flow, and pressure-test before you condemn the unit. The 46RE pump failure guide covers low-pressure checks, and the rebuild cost guide helps you plan for hard parts found at teardown.

Fitment

The kit is listed for 1990-up Dodge and Chrysler A518/46RE and A618/47RE units: Ram 1500, 2500 and 3500, Dakota and Durango, and Jeep Grand Cherokee on the 46RE side. The 47RE and 46RE share most internals but not every clutch stack, and the later 48RE is not named on this listing, so read the ID tag on the case and count your old plates before assembly. Send us the year and VIN if you want it checked. Browse more parts on the 46RE and 47RE collection page.

Install notes

• Inspect the pump, drums, overdrive sprag and the cast forward clutch retainer before assembly. A scored pump calls for a replacement pump.
• The overdrive clutch spring needs a compressor to service; a T-1302 style overdrive spring compressor makes that step safe.
• Soak the frictions in ATF+4 and air-check each pack.
• Per the 1998 factory manual, tighten both 47RE bands to 72 in-lb, then back the front off 1-7/8 turns and the rear 3 turns.
• Fill with Mopar ATF+4 and check it hot in Neutral. A deep finned cooling pan adds capacity for trucks that tow.

Will this kit fit my 2000 Ram 2500 Cummins?

The listing covers the A618/47RE in 1990-up Dodge trucks, which includes Cummins-powered Rams with the 47RE. Confirm the case tag and compare your old clutch plates to the kit before assembly.

Does it fit a 48RE?

The 48RE is not named on this listing. Some parts carry over, but send us your year and VIN before ordering for a 48RE truck.

Are the seals good for a truck that tows?

The seals are listed as fluororubber (FKM) and ACM compounds rated for high ATF temperature. Pair them with a clean, free-flowing cooler, since heat is what kills these units.

Does the kit include bands or a torque converter?

No. It includes frictions, steels, gaskets, seals, sealing rings and a filter. Bands, bushings, hard parts and the converter are separate.

What are the 47RE band adjustment specs?

The 1998 Chrysler service manual gives 72 in-lb on both bands, then back off the front band 1-7/8 turns and the rear band 3 turns.

What fluid does the 47RE use?

Mopar ATF+4. Do not substitute Dexron. Check level hot with the shifter in Neutral.
