Rebuilds the Dodge and Jeep 46RE, 47RE, A518 and A618 automatic with new frictions, steels, rubber seals, gaskets and a filter for a full bench overhaul, 1990-up.
This TRANSPEED master kit is the box of wear parts for a full bench rebuild of the Chrysler rear-wheel-drive four-speed overdrive automatic: the A518 (46RH and 46RE) and the heavier A618 (47RH and 47RE). Those units sit behind V8 and Cummins engines in Dodge Ram 1500, 2500 and 3500 trucks, Dakota, Durango and Jeep Grand Cherokee from 1990 on. If your truck slips into overdrive, flares between gears under a trailer, shows burnt fluid with friction paste on the pan magnet, or leaks from the pump and the pan rail, and the transmission is already coming out, this kit replaces every friction surface and seal you will touch. Inside are clutch friction plates, matching steel plates, the rubber and O-ring seal set, lip seals, sealing rings, the pump and case gaskets and a new pan filter.
These transmissions are a three-speed with an overdrive section bolted to the back. Four clutch packs (front, rear, overdrive and direct) and two bands do the work, and every clutch is applied by fluid trapped behind a piston by lip seals and by sealing rings on the shafts and support. A soft-parts kit restores both halves of that system at once: new frictions and flat steels so each pack can grip, and new seals and rings so apply oil reaches the piston instead of leaking past it. The included filter keeps the debris from the old failure out of the new clutches on the first drive.
Rule out the cheap faults first. A failed governor pressure solenoid or sensor, a sticking valve body bore or a restricted cooler can all mimic a worn-out unit on these trucks. Check the fluid hot, scan for codes and put a gauge on line and governor pressure. Our 46RE common problems and fixes guide walks through that order. If pressures fall off across several clutches and the pan is full of lining material, the unit needs a teardown, and our 46RE rebuild cost breakdown shows where the money goes beyond this kit.
The listing covers the 46RE, 47RE, A518 and A618, including the earlier 46RH and 47RH, for 1990-up Dodge and Jeep applications. The 46RE and 47RE share their basic architecture, but the 47RE behind the Cummins uses different clutch stack-ups in some packs, and parts changed across model years. Read the ID tag on the case, count your old plates at teardown and compare them to the kit before assembly. Not sure which unit you have? Send us the year and VIN. More parts for these trucks are on our 46RE collection page.
This kit does not include a torque converter, valve body, pump or other hard parts. If your pump gears or bushing are worn, a remanufactured 46RE pump is usually faster than rebuilding the old one.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes, the listing covers the 46RE, 47RE, A518 and A618, plus the older 46RH and 47RH. Because the 47RE uses some different clutch stack-ups, count your old plates at teardown and compare them to the kit before you assemble.
Clutch friction plates, steel plates, the rubber and O-ring seal set, lip seals, sealing rings, the pump and case gaskets and a new pan filter. It does not include the torque converter, bands, valve body or hard parts.
If the overdrive clutch is worn, the new frictions and seals restore it. If the overdrive sprag or the overdrive piston retainer seal has failed, those hard parts must be repaired as well, so inspect them at teardown.
Mopar ATF+4. Chrysler's 2004 Ram chart lists an overhaul fill of about 19 to 20 pints for the 46RE and 29 to 33 pints for the 47RE. The exact amount varies with the cooler and lines, so finish by checking the level hot.
Plan for any hard parts that fail inspection, a converter service or replacement, cooler line flushing and, on 1996-1999 trucks, a governor pressure solenoid and sensor if the old ones are suspect.
