47RE Pump 1994-2002, remanufactured and ready to install. Fits the 47RE. Ships fast from the USA.
A 47RE that hangs in Neutral before Drive catches, lets the converter clutch slip on a hot pull with a trailer behind it, or whines with engine RPM while the truck sits in Park is often a front pump problem. This is a fully rebuilt lockup-style front pump for the A618 family (47RH and 47RE, and it also covers the 46RH/46RE), listed for 1994-2002. The pump has been taken apart, cleaned, inspected and rebuilt with new gears, then torqued back together to the factory specification, so it bolts into the case as a finished assembly.
The 47RE pump bolts to the front of the case and is turned by the converter hub at engine speed. It is the only source of oil in the transmission. The pressure regulator takes its output first to set line pressure for the bands, clutches and servos, and the leftover volume charges the converter, flows through the cooler and lubricates the gear train. On the RH/RE family the converter clutch is applied with line pressure, and the 47RE only adds roughly 10-15 psi of line rise in third with the converter locked and in fourth. Sonnax contrasts that with 22-28 psi on the 48RE, which Chrysler built for diesel torque. With so little margin, a 47RE pump that has lost even some volume usually shows up first as converter slip and overdrive clutch wear on a loaded truck.
Sonnax ranks a restricted cooler as the most common cause of converter slip and slow engagement on these units, so test before you pull the transmission. Check the level hot in Neutral with ATF+4, drop the pan and look at the filter and debris, then put a gauge on line pressure and see whether it reaches maximum at fast idle. Measure cooler return flow with the cooler in circuit and again with it bypassed. Flow that stays low with the cooler bypassed points to the pump or converter. Our 47RE pump failure symptoms guide walks through each test on a Ram 2500 or 3500, and 47RE Ram 2500 common problems covers the governor and solenoid faults that can feel like pump trouble.
The listing covers 1994-2002 A518/A618 pumps (46RH, 46RE, 47RH, 47RE) in Dodge Ram trucks and full-size vans with the 5.2L, 5.9L and 8.0L V10 gas engines. On the 47RE side that means the heavy-duty V10 trucks. The rebuilder writes the listing around gas engines, so if your 47RE is behind a 5.9L Cummins, compare the casting number, stator shaft and stator bushing on your old pump with this one, or send us your year and VIN and we will confirm it before it ships. Chrysler made running changes to the stator support over these years, and 2003 47RE and later 48RE units should always be checked first. Every other 47RE part we carry is on the 47RE collection page.
If the converter never locked before the pump went bad, test the 47RE lockup solenoid while the pan is off. A truck with a soft 3-4 and a weak governor reading may also need the 47RE governor solenoid kit.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The listing is written for 1994-2002 Ram trucks and vans with the 5.2L, 5.9L and 8.0L V10 gas engines, which on the 47RE side means V10 trucks. For a Cummins 47RE, compare the casting number, stator shaft and stator bushing on your old pump first, or send us your year and VIN and we will confirm fitment.
It was disassembled, cleaned, inspected and rebuilt with new gears, then torqued back together to the factory specification. It installs as a complete pump assembly.
Yes. The converter clutch on the 47RE is applied with line pressure, and the 47RE only adds about 10-15 psi of line rise in fourth. A pump that cannot hold line under load lets the converter slip. Test cooler flow first, because a restricted cooler causes the same complaint.
This one is the lockup-style rebuilt pump with new gears listed for 1994-2002. The 1994-03 pump is described by its rebuilder as a non-lock-up style with two check balls and a 1.250 inch stator rear bushing. Match the style and stator bushing to your old pump.
Chrysler lists a 47RE service fill of 8 pints and an overhaul fill of 29 to 33 pints, depending on the converter and cooler. Fill close, then set the final level hot in Neutral on the dipstick.
A new front seal and gasket, a flushed or new cooler and lines, and an inspected converter hub and crank pilot. If the pan shows friction or band material, rebuild the rest of the unit while it is out.
