46RE Pump 1994-03, remanufactured and ready to install. Fits the 46RE. Ships fast from the USA.
If your 1994-2003 Dodge Ram pickup or full-size van with the A518 (46RH/46RE) or A618 (47RH/47RE) sits in Neutral for a second before Drive or Reverse catches, whines with engine speed even in Park, or gets lazy once the fluid is hot, the front pump is high on the suspect list. This is a complete remanufactured pump for that 1994-2003 range: the pump body has been machined back to specification, the stator support face cut, and it is built with the later 1.250 inch stator rear bushing. It arrives with a new pump body bushing, front seal, pump-to-case gasket, front pump O-ring and the two stator support sealing rings, so it is ready to go into the case.
The 46RE pump is a gear-type pump bolted to the front of the case and driven by the torque converter hub, so it only turns as fast as the engine. Its output feeds the pressure regulator first, and what is left over charges the converter, flows through the cooler and lubricates the gear train. Because line pressure is protected first, a worn pump usually starves the converter and cooler circuits before it ever lets a clutch slip. The stator support bolted to the pump body also centers the turbine shaft in the converter, and its sealing rings keep converter apply and release oil apart. That is why the bushing size and stator details on this unit matter as much as the gears.
A restricted cooler causes nearly the same list of complaints, and Sonnax ranks cooler restriction as the most common cause. Check the fluid level hot in Neutral, pull the pan and look at the filter and debris, then put a gauge on it. A healthy pump reaches maximum line pressure at fast idle; a reading that is low at idle and recovers with RPM, or falls off as the fluid warms, points at pump wear. A bouncing needle with a whine usually means air from a cracked or unseated filter, not a bad pump. Then check cooler flow from the lower line with and without the cooler bypassed. Our 46RE pump failure symptoms guide walks through each test in order.
This pump is listed for the A518/46RH/46RE from 1994 to 2003 and the A618/47RH/47RE from 1993 to 2003. It uses the 1.250 inch ID stator rear bushing and will not fit 1993 and earlier units built with the 1.170 inch ID stator bushing. The rebuilder describes it as the non-lock-up style pump with two check balls, so before ordering pull your old pump, or compare against your rebuild records, and match the stator bushing size and check ball count. If you are unsure, send us your year and VIN and we will confirm it before it ships. You can see every 46RE part we carry on the 46RE transmission parts page.
If the pan shows burned frictions or band material, the debris that wore the pump is also in the clutch packs, and the 46RE overhaul kit belongs in the same teardown. Trucks with a 3-4 slip should also get the overdrive one-way clutch looked at; the 46RE sprag clutch is the usual wear item there. For the bigger picture on this family, see what breaks on the 46RE, 47RE and 48RE.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Only if your transmission has the 1.250 inch ID stator rear bushing. The listing covers 1994-2003 A518/46RE and 1993-2003 A618/47RE units and specifically will not fit 1993 and earlier units that use the 1.170 inch ID stator bushing. Measure your old pump or send us your VIN.
The complete pump with the body machined and the stator support face cut, plus a new pump body bushing, front seal, pump-to-case gasket, front pump O-ring and two stator support sealing rings.
Check cooler flow from the lower line, then bypass the cooler and check again. If flow comes back with the cooler bypassed, the cooler or lines are restricted. If it stays low in every condition, look at the pump or converter. A gauge test that is low at idle and recovers with RPM also points at the pump.
Yes. The two halves have to be aligned before the bolts are torqued to the factory specification. An unaligned pump can bind or leak once the converter is installed.
ATF+4. Chrysler lists the 46RE service fill at 8 pints and the overhaul fill at 19 to 20 pints, with the exact amount depending on the cooler and lines. Fill close, then set the level hot in Neutral on the dipstick.
Clean or replace the cooler and lines, check the converter hub and crankshaft pilot, and if the pan shows clutch or band material, rebuild the whole unit with an overhaul kit while it is out.
