44RE Pump 1994-05, used and ready to install. Fits the 44RE. Ships fast from the USA.
A Jeep Grand Cherokee, Cherokee, Wrangler or Dodge Dakota with the small four-speed automatic that takes several seconds to drop into Drive or Reverse when warm, whines with engine speed, or slips in every gear usually has a pressure problem, and pressure starts at the front pump. This is a used, cleaned front pump assembly for the Chrysler A500 family sold as the 42RH, 42RE and 44RE, built for the lock-up converter years from the mid-1990s into the 2000s. The listing references interchange number 12500CG and Chrysler number 4778552, includes a pump gasket, and ships from the USA.
The pump bolts into the front of the case and is driven directly by the torque converter hub, so it turns any time the engine runs. Inside the pump body an inner and outer gear set draws fluid from the pan and feeds the regulator valve, which sets line pressure for every clutch, band, the governor circuit, the converter and the cooler. The reaction shaft support that bolts to the pump body carries the stator spline and the sealing rings that feed the front and rear clutches, so a worn support or a scored bushing leaks pressure exactly where the clutches need it. The factory manual lists tight gear clearances for a reason: 0.0004-0.0025 in. between the gears and the support face, and 0.0035-0.0075 in. at the gear tips and between the outer gear and the body.
Check the fluid level and condition first; a low level will mimic every symptom above. The factory pump volume check is simple: with the engine at curb idle in Neutral, disconnect the cooler feed line and time the flow into a container. If it takes more than 20 seconds to collect one quart, or the flow is intermittent, the manual has you rule out the cooler next by checking at the other line. A pressure gauge reading at the line pressure port confirms low output across every range. Our RE-series pump failure guide walks through the same tests on the bigger 46RE, and the logic carries straight across to the A500. If the problem is only a slow engagement, read the delayed engagement fix first, since a stuck regulator valve or a bad input-shaft sealing ring can look just like a tired pump.
This pump is listed for 1994-2005 lock-up 42RE and 44RE units (A500 family, including late 42RH). Match every point below to your old pump before ordering:
Earlier non-lock-up units and the larger 46RE/47RE pump will not interchange. If anything does not match, send your year and VIN and we will confirm before it ships. See every part for this unit on the 42RE/44RE collection page, or compare the sibling 44RE pump for 1995-2005.
A pump that failed from heat or contamination usually means the clutches suffered too. If the fluid was burnt, plan on an overhaul kit or a full A500 master rebuild kit while the unit is apart.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is built for lock-up 42RE/44RE (A500) units from 1994-2005. Match the 14-hole gasket, flat-milled inner gear, three-ring input shaft, 27-spline stator support and casting 52118268 or 52118996AA. Send your year and VIN if you are unsure.
No. The 46RE and 47RE use a larger pump and case. This pump is only for the small-case A500 family.
Set the level correctly first. Then run the factory volume check: at idle in Neutral the cooler line should deliver one quart in 20 seconds or less. Slow or intermittent flow plus low line pressure in every range points to the pump or its sealing rings.
A new front seal, pump O-ring and gasket at minimum. Inspect the converter hub, flush the cooler, and if the fluid was burnt, rebuild the clutches with an overhaul or master kit.
Use ATF+4. Chrysler originally specified ATF+3 for these units, and ATF+4 superseded it.
No electronic relearn is needed for the pump. Fill the transmission before the first start so the pump is primed, and check the level hot once it is running.
