41TE Pump 2000, remanufactured and ready to install. Fits the 41TE. Ships fast from the USA.
A Caravan, Town and Country, Sebring or Stratus with the 41TE that groans as the engine revs, takes a second or two to grab Reverse in the morning, or feels like it slips in every gear may be losing pump output. This is a complete OEM 41TE (A604) front pump assembly for 2000-up transaxles. It ships with a new pump bushing, new front seal, new pump gasket and new O-ring, so the wear and leak points that matter most on a pump swap are fresh.
The 41TE uses a gear-type pump bolted to the front of the case and driven by the torque converter hub. Every pound of pressure in the transaxle starts here. Pump flow goes to the pressure regulator in the valve body, and from there to the underdrive, overdrive, reverse, 2-4 and low/reverse clutches, to the converter, through the cooler and into the lube circuit. The pump also holds the stator support. Its sealing rings route apply oil to the input clutches, and the input clutch hub bushing rides on it. Sonnax describes that bushing as an oil control surface for the underdrive clutch: too much clearance against the stator support lets underdrive pressure escape and the clutch burns. That is why a 41TE with a worn pump can keep eating clutch packs.
Start with the basics: correct ATF+4 level and fluid that is not burnt. A scan tool that reads clutch volume index values tells you a lot. A single high value isolates one clutch, while slip in every gear with several values climbing points to low pressure. On the 41TE, many slip complaints are actually electrical or solenoid faults that drop the unit into its second-gear default, so work through the 41TE Ultradrive problems guide first, then the 41TE slipping under load guide for pressure testing.
This pump is listed for 2000-up 41TE (A604) transaxles in Chrysler and Dodge front-drive vehicles. The pump gearset changed around the 2000 model year, and units built during the changeover can carry either design, so the model year alone is not enough. Compare your old pump to the photos, count the inner gear teeth and measure the stator shaft before you buy, or send your year and VIN and we will confirm it. Earlier 1989-1999 units use the older pump and do not take this one. Browse every 41TE part in the 41TE collection.
With the transaxle out and the converter removed, take out the pump bolts and use slide hammers or puller bolts in the threaded holes to draw the pump straight out. Keep the input shaft and clutch hubs from moving forward with it. Inspect the input clutch hub bushing and the sealing ring grooves, since this pump cannot fix clearance on the other side of that joint. Lube the new O-ring, seat the gasket, draw the pump in evenly and torque in a cross pattern, then spin the input shaft by hand to make sure nothing binds.
Fill with ATF+4 only, check the level hot, and run the quick learn so the TCM resets clutch volumes. If the old fluid was black or loaded with lining material, overhaul the clutches at the same time with a 41TE master rebuild kit and flush the cooler. For a less expensive used-OEM alternative with the long stator shaft, see the 2000-06 41TE pump.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is listed for 2000-up units. Earlier A604/41TE transaxles used a different pump gearset, and transitional units built around 2000 can have either, so count the inner gear teeth on your old pump.
A new pump bushing, new front pump seal, new pump gasket and new pump O-ring come with the OEM pump assembly.
It can. Low pressure causes clutch slip, the TCM sees the speed ratio error and sets a code, then defaults to second gear. Rule out solenoid and wiring faults first, because they cause the same limp mode.
ATF+4 only. Other fluids change friction behavior and can cause shudder and shift complaints in the 41TE.
Yes. Run the quick learn with a capable scan tool once the unit is filled and at temperature, so the TCM relearns clutch fill volumes.
