The 46RE and 47RE are Chrysler's four-speed rear-drive automatics: a three-speed TorqueFlite-based main case with an overdrive unit bolted on the back. Earlier versions were called the A518 and A618, and the hydraulic-governor versions were badged 46RH and 47RH. You find them in Dodge Ram pickups and vans, Dakota, Durango and Jeep Grand Cherokee, with the 47RE behind the heavier engines and the 5.9 Cummins.
An overhaul gasket and seal kit is the base of every rebuild on these units, and the right buy by itself when the clutch plates still measure good but the unit leaks or loses apply pressure.
What Is in the Box
A 46RE / 47RE overhaul kit replaces the soft parts that seal fluid between the pump, the case and the four clutch packs. The 1990-2003 kit we stock includes:
- Lip seals for the front, rear, overdrive and direct clutch pistons
- Servo and accumulator seals for the kickdown and low-reverse band servos
- Sealing rings for the reaction shaft support, input and output shafts and overdrive housing
- Metal-clad seals including the front pump seal
- Gaskets and O-rings for the pump, case, overdrive unit and adapter
- Pan gasket and a small parts bag
Not included: friction plates, steels, bands, bushings or a filter. For the difference between kit types, see rebuild kit vs master overhaul kit.
Fitment: RH, RE, and Why the 48RE Is Different
| Unit | Governor | This Kit? |
|---|---|---|
| 46RH / 47RH | Hydraulic (mechanical) governor | Yes, 1990-2003 kit |
| 46RE / 47RE | Electronic governor pressure solenoid and sensor | Yes, 1990-2003 kit |
| 48RE | Electronic | No. Order a kit listed for the 48RE |
Because one kit spans both governor styles and 14 model years, it carries more than one version of some seals and gaskets. Match each new part to the one you removed and discard the extras. If your truck is a 2003-up Cummins with the 48RE, shop 48RE parts instead.
The Leaks and Pressure Losses a Reseal Fixes
- Front pump seal. Fluid at the bottom of the bell housing. A worn pump bushing or converter hub will ruin a new seal, so check both. See front pump seal leak symptoms.
- Overdrive unit gasket. Fluid at the joint between the main case and the overdrive housing.
- Rear seal. At the extension housing on 2WD trucks, or the adapter housing on 4WD.
- Pan gasket. Common after several pan drops. Torque evenly and do not over-tighten.
- Clutch piston and servo seals. Hardened lips leak apply pressure away before it reaches the piston. The result is slipping, late engagement and more heat, which ages the remaining seals faster.
- Sealing rings. Worn rings on the reaction shaft support and overdrive housing bleed pressure to the spinning drums.
The pan and rear seal can be done in the truck. Everything else means the transmission comes out, so reseal the whole unit while it is on the bench.
Buying Tips From the Bench
- Measure the clutches before ordering frictions. If the steels are flat and clean, this kit plus a friction pack is cheaper than a master kit.
- Soak lip seals in ATF and use assembly lube that dissolves in ATF.
- Drive the pump seal in square with a seal driver.
- RE units: check the governor pressure solenoid and sensor while the pan is off. See the 46RE governor pressure solenoid guide.
- Add a filter. The kit does not include one. See the 46RE / 47RE / 48RE filter and pan kit guide.

FAQ
Does a 46RE overhaul kit include clutches or bands?
No. It is the gasket and seal kit only: lip seals, O-rings, metal-clad seals, sealing rings and gaskets. Frictions, steels, bands, bushings and the filter are bought separately.
Does the same kit fit a 46RE and a 47RE?
Yes. The 1990-2003 kit covers the 46RH, 46RE, 47RH and 47RE.
Will it fit a 48RE?
No. The 48RE used in later Cummins trucks needs a kit listed for the 48RE.
Why are there extra seals left over?
The kit covers both hydraulic-governor RH units and electronic-governor RE units across 14 years, so it carries more than one version of some parts. Match each new part to the one you removed.
Can I fix a 46RE front seal leak without pulling the transmission?
The front pump seal sits behind the torque converter, so the transmission has to come out. If it is out, reseal the whole unit.
