45RFE Pump 1999-2006, used and ready to install. Fits the 45RFE. Ships fast from the USA.
A 4.7L Ram 1500, Dakota, Durango or Grand Cherokee from 1999 to 2006 with a 45RFE that will not pull into gear until it is revved, whines with the engine, or keeps logging low line pressure is often a pump job. This is a good used complete pump assembly for the 45RFE and 5-45RFE behind the 4.7L, the version with the front seal pressed into the pump body. It is identified by part number 68004735AC, which is superseded by 05072589AE, and it is a far cheaper path than a new or remanufactured pump if your old one is scored or cracked.
The converter hub turns the pump gears at engine speed, and the gears draw fluid from the pan and push it out as main line pressure for the solenoid pack and every clutch. Inside the pump body sit the pressure regulator valve and the converter clutch valves, so the pump decides both how hard the clutches apply and whether the converter can lock. The transmission computer commands pressure through the pressure control solenoid and checks it with a line pressure sensor, which is why a weak pump often shows up first as a scan-tool mismatch between desired and actual pressure.
On 1999 to 2006 trucks in particular, check one thing first: Chrysler TSB 21-016-05 traced a delayed first engagement after sitting overnight to converter drainback through the AB-level cooler return filter, 04799662AB. If your delay is only on the first start of the day, that filter is the likely cause, not the pump. Otherwise, verify the fluid level hot with ATF+4, inspect the pickup filter seal for air leaks, and watch line pressure as the unit warms. Our 45RFE pump failure guide explains the scan data to look for, and the pressure control solenoid guide covers the electrical causes of the same codes.
This pump is listed for Dodge and Jeep 45RFE and 5-45RFE automatics from 1999 to 2006 behind the 4.7L engine, with the front seal in the pump body. That covers 4.7L versions of the Ram 1500, Dakota, Durango and Grand Cherokee in those years. If your truck has a 3.7L or 5.7L, or was built near a model-year changeover, match the part number on your old pump to 68004735AC or 05072589AE, or send us your year and VIN before ordering. More options for this transmission are on the 45RFE collection page.
Since this is a used pump, inspect it before it goes in: check the gear pockets and body face for scoring, confirm the spacer plate screws are tight, and replace the front seal and bushing. A worn valve bore can be restored with the 45RFE pump valve repair kit. Install a fresh pickup filter and pan gasket, such as the RFE oil pan and filter kit, so the replacement pump is not starved by a clogged filter or an air leak. Align the pump to the case, check the converter hub for grooves, prime with ATF+4, and flush the cooler and lines. A service fill on a 4x2 is about 5.2 liters, while an overhaul fill runs 14 to 16 liters. For problems elsewhere in the unit, see our 45RFE and 545RFE problems guide.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 1999-2006 45RFE and 5-45RFE units behind the 4.7L engine, with the front seal in the pump body. For other engines, match your old pump's part number or send your VIN.
The pump is identified by part number 68004735AC, superseded by 05072589AE. Compare that with the number on your original pump.
Probably not. TSB 21-016-05 covers converter drainback through the 04799662AB cooler return filter, which causes a delay only after sitting. A pump usually gets worse as the fluid warms.
Replace the front seal and bushing, install a new pickup filter and pan gasket, inspect the converter hub, and flush the cooler. Use ATF+4.
No. It is a good used pump assembly. Inspect the gears and clearances and replace the seal before installing it.
