66RFE Pump 2012-18, new and ready to install. Fits the 66RFE. Ships fast from the USA.
If you have the front pump of a 2012-2018 Ram 1500, 2500 or 3500 on the bench and the cover is scored, cracked or bent, this is the part you are looking for. This listing is a single genuine Mopar oil pump cover, part number 68009859AC, for the 65RFE and 66RFE. It is the cover only, shown as reference number 3 in the factory parts diagram. It is not a complete pump: there are no gears, no pump body, no stator support and no front seal in the box. Builders usually order it after teardown, when the rest of the pump checks out and only the cover is unusable.
The RFE front pump is a bolted-together assembly. The converter hub drives the pump gears, and the gears push fluid out to the pressure regulator, which sets line pressure for the whole transmission. The pump cover is one of the faces that closes that assembly and keeps the fluid where it belongs. Its sealing surface has to stay flat and clean. If it is warped from overheating, gouged by debris, or the molded sealing edge is torn, pressurized fluid bypasses back to the suction side instead of going out to the clutches and the converter. The result looks like a weak pump even when the gears are fine.
The pump in this family also carries several valves, including the pressure regulator and the converter clutch valves. If you are already inside the pump, it is the cheapest time to renew them. Our RFE pump valve repair kit for 1999-2018 covers those four valves.
A cover is not something you diagnose from the driver's seat. Low pressure on an RFE has cheaper causes, starting with a doubled-up filter O-ring sucking air and a level read before the fluid reached temperature. Work through the line pressure checks in our RFE pump failure diagnosis guide first. The guide is written around the 68RFE, but the 65RFE and 66RFE share the same pump layout and the same test logic. Once the pump is out, check the gear pocket, the center gear bore and the cover face separately. Pocket face damage on the body means a complete pump. A damaged cover on an otherwise good pump is what this part fixes.
This cover fits the 2012-2018 Ram 1500, 2500 and 3500 equipped with the 65RFE or 66RFE automatic, per the Mopar listing. Hold your old cover beside the photo and compare it before you order. If the part number on your old cover or in your parts catalog differs from 68009859AC, send us your year and VIN and we will check it. Other RFE parts for these trucks are listed on our RFE transmission parts page.
For other common problems on these trucks, see our RFE valve body testing guide, since valve body leaks can look a lot like a weak pump.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is only the oil pump cover, Mopar part number 68009859AC, shown as reference 3 in the factory diagram. Your pump body, gears, stator support and seals are reused or bought separately.
The listing covers 2012-2018 Ram 1500, 2500 and 3500 trucks with the 65RFE or 66RFE automatic. Compare it with your old cover or send us your year and VIN if you want us to check.
Yes. If the cover face is warped or scored, or its seal is damaged, fluid leaks back inside the pump instead of building pressure. Rule out the filter O-ring and the fluid level first, since those cause the same symptom for much less money.
Plan on a new front seal, a pump bushing if the old one is worn, and fresh ATF+4. If the pump valves are worn or the bores show leakage, renew them at the same time with an RFE pump valve repair kit.
Mopar ATF+4 (MS-9602-F). Check the level hot, with the fluid at 160 degrees F or more, because a cold reading on these transmissions is not accurate.
