68RFE Pump 2007-2018, new and ready to install. Fits the 68RFE. Ships fast from the USA.
The 2007 through 2018 Ram heavy-duty trucks with the 6.7L Cummins and 68RFE are the ones that spend the most time hooked to fifth-wheels, goosenecks and work trailers, and that is exactly the duty that wears out a transmission pump. When the pump loses volume, owners notice the truck flaring between shifts on a grade, engagement into gear taking a beat too long after a long pull, and a steady whine at idle that changes with the throttle. This new pump assembly for 2007-2018 68RFE units, shown with its stamped steel front housing, puts full supply volume back under the valve body.
The 68RFE pump sits directly behind the torque converter. The converter hub drives a center gear, and two outer gears around it move fluid into the pressure circuit. The transmission controller regulates that supply through the pressure control solenoid and constantly compares the pressure it asked for to what the transducer reports. As the pump wears, the controller compensates by commanding more and more pressure until it runs out of room. At that point clutches start to slip, heat climbs, and the damage spreads to the friction packs and converter. On these trucks the pump is also the first link in the cooling loop, since it supplies the fluid that flows through the cooler.
Line pressure tells the story. With a scan tool, graph commanded and actual pressure plus duty cycle after the fluid reaches operating temperature. GEARS Magazine reports a healthy 68RFE at about 60 to 70 psi at idle with duty cycle near 22 to 24 percent. Actual pressure below commanded with the duty cycle maxed out means the supply side is weak. Pressure reading above commanded points the other direction, toward the pressure control solenoid circuit, not the pump. Check the sump filter and its O-ring for a suction leak first, since a stacked or half-seated O-ring after a recent service produces the same reading. Our 68RFE pump diagnosis guide lays out the full sequence, and the Ram 3500 shift problems guide helps separate pump slip from solenoid and sensor faults.
This pump is listed for 68RFE transmissions from 2007 through 2018, the span before the 2019 redesign that Transmission Digest notes added a separate TCC solenoid and other changes. That covers Ram 2500 and 3500 pickups with the 6.7L Cummins in those years, and the 68RFE also appears in Ram 4500 and 5500 cab-chassis trucks. Production changes happened inside that window, so match your old pump against the photos, including the housing shape and reaction shaft, or send us your year and VIN and we will confirm it before it ships. All of our parts for this unit are on the 68RFE parts page.
Because these trucks run hot under load, the cooling side deserves attention during the job. On 2013-2018 trucks a sticking 68RFE thermal bypass valve can keep fluid from reaching the cooler at all, and if the pump failed from heat the clutches have usually suffered too, which is where an 68RFE overhaul kit for 2011-2018 comes in.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 68RFE transmissions from 2007 through 2018, which covers the 6.7L Cummins Ram 2500 and 3500 in those years. Changes were made during production, so compare your old pump to the photos or send your year and VIN so we can confirm before shipping.
No. The 2019 update brought several internal changes, so this 2007-2018 listing should not be assumed to fit a 2019-up truck. We list later-year pumps separately.
A worn pump can keep up at light load but cannot meet the demand of a heavy trailer, especially once the fluid is hot and thinner. Pressure drops below what the clutches need, so they slip and generate more heat, which is why towing complaints often come before daily-driving ones.
At minimum flush the cooler and lines, because a failed pump sends debris downstream. If the truck has been running hot, check the thermal bypass valve on 2013-2018 trucks and confirm the cooler flows freely before blaming the new pump for heat.
Mopar ATF+4 (MS-9602-F). Prime the pump during assembly, fill, then idle in Park until the fluid reaches at least 160 degrees F before setting the final level.
No. P0868 is a low line pressure code and can be caused by low or overfilled fluid, a filter O-ring suction leak, or a worn valve body bore. Rule those out first, then confirm with a pressure graph.
