46RE Pump 1994-2002, remanufactured and ready to install. Fits the 46RE. Ships fast from the USA.
A 1994-2002 Dodge Ram, full-size Dodge van or Jeep with the 5.2L, 5.9L or 8.0L V10 gas engine and a 46RE or 47RE that is slow to go into gear, loses converter lockup on the highway, or howls with engine RPM is telling you the front pump may be done. This is a fully rebuilt lockup-style pump for the A518/A618 family (46RH, 46RE, 47RH, 47RE). It has been disassembled, cleaned, inspected and rebuilt with new gears, then torqued back together to factory specification, so it goes into the case as a complete assembly rather than a pile of parts to fit.
In the 46RE and 47RE the converter hub drives a gear-type pump at engine speed. That oil supplies the pressure regulator, which sets line pressure and then sends the remainder to the converter, the cooler and the lube circuit. On this family the converter clutch is applied with line pressure fed straight from the manual valve, and Sonnax puts stock maximum line near 130 psi in Drive or fourth. There is not much headroom: a pump that cannot hold line under load cannot hold the converter clutch either, which is why lockup complaints are often the first sign of a worn pump on these trucks.
Rule out the easy causes first, because a plugged cooler produces the same complaints. Check the level hot in Neutral and inspect the filter and pan debris. On these trucks you can log Governor Actual on a scan tool in fourth above about 40 mph, where it reads line pressure; if it sags as the fluid heats or drops when the converter applies, the pump is suspect. Confirm with a mechanical gauge, then compare cooler flow with the cooler connected and bypassed. A flow problem that stays with the cooler bypassed points to the pump or converter. The full test sequence is in our 46RE pump failure symptoms guide, and the 46RE common problems guide covers the governor and solenoid faults that can feel like pump trouble.
This listing covers 1994-2002 46RE and 47RE transmissions with a lockup converter, including the 46RH and 47RH, in Dodge Ram pickups, full-size Dodge vans and Jeep applications. It is listed under casting number 4505031, the 1994-up pump. Chrysler made running changes to the stator support and bushing over the years, so compare the casting number and stator bushing size on your old pump before you order, or send us your year and VIN and we will check it. 2003-up and diesel 47RE and 48RE units should be confirmed with us first. Browse the rest of the family on our 46RE parts collection.
If you are adding line pressure with a 46RE shift kit at the same time, remember converter apply rises with line on this family, so set it up deliberately rather than using pressure to cover wear. Trucks with burned frictions in the pan should get the 46RE overhaul kit 1990-2003 while everything is apart.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The listing is written for gas trucks and vans with the 5.2L, 5.9L and 8.0L V10. Diesel 47RE and later 48RE units should be confirmed with your old pump's casting number or your VIN before ordering.
This one is the lockup-style rebuilt pump listed for 1994-2002 under casting 4505031 with new gears. The 1994-03 unit is described as a non-lock-up style pump with two check balls and the 1.250 inch stator bushing. Match the style and stator bushing on your old pump.
Yes. On the 46RE and 47RE the converter clutch is applied with line pressure, so a pump that cannot hold line under load lets the converter clutch slip, shudder or drop out. Test the cooler flow first, because a restricted cooler causes similar symptoms.
Yes. The pump bolts to the front of the case behind the torque converter, so the transmission comes out. Inspect the converter hub and crank pilot while it is out.
ATF+4. Chrysler lists 8 pints for a 46RE service fill and 19 to 20 pints after an overhaul. Check the final level hot in Neutral.
