68RFE Pressure Control Solenoid 2007-2018, new and ready to install. Fits the 68RFE. Ships fast from the USA.
The name on this listing says pressure control solenoid, but the part is something else entirely: a RevMax billet aluminum oil pump body, manufacturer part number 68RFE-626, for the 68RFE behind the 6.7L Cummins in 2007.5-2018 Ram 2500 and 3500 trucks. It replaces the cast pump body half of the front pump. Builders reach for it when a rebuilt 68RFE keeps losing line pressure, slips when hot, or wears out converter clutches, and the cause turns out to be a pump body that is no longer flat. If you came here looking for a line pressure solenoid, that part is built into the solenoid block on top of the valve body, not sold as a loose piece.
The front pump is the only source of oil for the whole transmission. In the 68RFE the gears turn inside the pump body, and the body and stator halves sandwich a separator plate that routes oil to the pressure regulator, converter clutch circuits and lube. Every one of those circuits depends on flat sealing faces. According to RevMax, cast bodies warp over thousands of heat cycles, with used bodies seen up to .020 in. out of flat. Sanding a warped body flat lowers the gear pocket and eats into the roughly .002-.003 in. gear-to-plate clearance a new factory pump has, so the gears can rub the plate. A body that will not stay flat cross-leaks oil between circuits, which shows up as low line pressure and weak converter apply under load.
Put a gauge on the line pressure port and compare idle and stall readings with the truck hot. If pressure is low and the solenoid block and line pressure sensor check out, the pump is the next suspect. On the bench, check the pump body face against a surface plate or a precision straightedge and look at the gear pocket for scoring. Our 68RFE pump failure guide walks through the full pump diagnosis, and the Ram 3500 Cummins common problems guide covers the towing-heat failures that usually lead here.
RevMax lists this body for 2007.5-2018 68RFE transmissions in the Ram 2500 and 3500 with the 6.7L Cummins, for stock or aftermarket built units. It is not listed for the 2019-up 68RFE, which went through a round of design changes including the blue-connector valve body. You get the pump body only. It is made to work with a new, used or rebuilt stator half, and the stator can be resurfaced conventionally if its valve train passes inspection. If you are not sure which 68RFE you have, send us your year and VIN. See every 68RFE part we carry in the 68RFE collection.
The manufacturer describes the body as 6061 billet, CNC machined, flat to within .0003 in. and much thicker than the factory casting so it resists warping. No core return is required.

No. Despite the listing name, this is a billet oil pump body for the 68RFE front pump. On the 68RFE the line pressure solenoid is part of the solenoid block on the valve body and is not sold separately.
No. It is the pump body only. Reuse your gears if they are in good shape or replace them, and pair the body with your existing stator after inspecting and resurfacing it, or with a new or rebuilt stator.
It is listed for 2007.5-2018 68RFE transmissions only. The 2019-up unit had several design changes, so it is not a listed fit.
Sanding the body flat lowers the gear pocket and reduces the small clearance between the gears and the separator plate, so the gears can drag on the plate. A new flat body restores that clearance.
The separator plate, pump seals and gaskets at minimum, and the pump gears if they are scored. Inspect the pressure regulator and converter clutch valves in the stator as well. Fill with ATF+4 when finished.
