45RFE Pump 1999-2018, new and ready to install. Fits the 45RFE. Ships fast from the USA.
This is not a complete pump. It is a new pump valve repair kit for the 45RFE, 5-45RFE and 68RFE from 1999 through 2018, for the rebuilder or shop that has a good pump body and gears but worn valve bores. If your Ram, Durango, Dakota or Jeep keeps setting line pressure or converter clutch slip codes after a rebuild, or the pump you pulled has gears in good shape but a sloppy pressure regulator valve, this kit restores the hydraulic side of the pump without replacing the whole assembly.
The kit contains four valves: the pressure regulator valve, the TCC switch valve, the TCC regulator valve and the TCC limit valve. The valves are slightly oversized so they take up the clearance in a worn aluminum bore without the bore being reamed first. In an RFE pump, those four valves do much of the real work. The pressure regulator valve sets main line pressure for the whole transmission, with the pressure control solenoid acting on its end to raise or lower it. The TCC switch and regulator valves route and meter converter clutch apply and release oil, and the limit valve controls the oil feeding the converter. When the valves and bores wear, oil leaks past them, and the result shows up as low pressure or a converter clutch that will not hold.
Sonnax links low pump pressure on these units to pressure regulator valve wear or damaged pump gears, and TCC slip codes to wear in the TCC regulator or switch valve. This kit addresses the valve side of both.
Watch line pressure on a scan tool while the fluid heats. If the computer is driving the pressure control solenoid toward maximum pressure and actual pressure still falls short, the leak is in the pump, its valves or a downstream circuit. On the bench, a valve that rocks side to side in its bore or a bore with visible polish is a candidate for this kit. If the pump gears or gear pockets are scored, a kit will not fix it and the pump needs replacing. Our 45RFE pump failure guide shows how to separate the two, and the valve body testing guide covers the matching bore wear in the main valve body.
The kit is listed to fit all 45RFE, 5-45RFE and 68RFE applications from 1999 to 2018, which covers the Ram 1500, Dakota, Durango, Grand Cherokee, Commander and Liberty on the smaller units and the Ram heavy-duty trucks on the 68RFE. Pump bodies did change over those years, so compare the new valves with the ones you remove before assembling, and send us your year and VIN if anything does not line up. Browse the rest of the range on the 45RFE collection page.
Separate the pump halves, remove one valve train at a time so springs and retainers stay in order, and clean the bores before fitting the new valves. Each valve should slide freely under its own weight when the bore is clean and oiled with ATF+4. While the pump is apart, check the gear clearances, replace the bushing and front seal, and confirm the spacer plate screws are tight, since ATSG found loose screws in a line pressure passage on early pumps. Reassemble with a new gasket set from a 45RFE overhaul kit or the 1999-05 master rebuild kit, prime the pump before first start, and flush the cooler. If your core is beyond saving, a complete used 45RFE front-seal pump gives you a body to put these valves in.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is a pump valve repair kit containing the pressure regulator valve, TCC switch valve, TCC regulator valve and TCC limit valve. You reuse your pump body and gears.
The valves are listed as slightly oversized and no-ream, so they are made to fit worn bores without reaming. Clean the bores and check that each valve moves freely before assembly.
It can if the cause is pressure regulator valve wear. P0868 can also come from a weak pump, an air leak at the pickup, a sticking pressure control solenoid or a faulty pressure sensor, so diagnose first.
The kit is listed for 45RFE, 5-45RFE and 68RFE units from 1999 to 2018. Compare the new valves with your originals and send your year and VIN if you want us to check.
Replace the pump bushing, front seal and pump gaskets at the same time, check gear clearances, and flush the cooler. ATF+4 is the correct fluid.
