65RFE Sprag Clutch 1999, used and ready to install. Fits the 65RFE. Ships fast from the USA.
If your Ram 1500, Dakota, Durango, Grand Cherokee or Commander moves fine in reverse and pulls in second, but sits there or slips when you take off in Drive, the one-way clutch that holds first gear is a prime suspect. This is a used factory low/reverse one-way clutch assembly, Chrysler part number 4799465, from the RFE family that started with the 45RFE in the 1999 Jeep Grand Cherokee and carried on in the 545RFE and the 65RFE. Our unit was taken out of a 2003 Ram 1500 with the 3.7L and the 45RFE, so it is a genuine OEM part, not a reproduction.
Chrysler built these transmissions around three planetary gearsets, three input clutches and three holding clutches, and there are no bands. The one mechanical holding device without a piston is the overrunning clutch, which most shops call the low sprag. In first gear it locks the low/reverse gear train to the case so the planetary set can drive the output shaft forward. In first the low/reverse clutch only works for a moment as the truck launches; after that it lets go and the one-way clutch holds first gear by itself. When the TCM shifts into second, the one-way clutch simply freewheels, so the 1-2 shift does not need two clutches timed against each other. In manual low, the low/reverse clutch stays on so you still get engine braking.
Compare Drive and manual low. Low keeps the low/reverse clutch applied and covers for a slipping one-way clutch; Drive does not. If the vehicle pulls in low and slips in Drive first, and reverse is strong, the sprag is the likely cause. Rule out the cheap items first: check the fluid level hot, look for a cracked primary filter, and watch line pressure on a scan tool. Our 45RFE no-movement diagnosis guide covers how to sort out pressure, filter and valve body faults, and the 45RFE slipping guide shows how to work out which gear and which clutch is actually slipping.
Our product title says 65RFE 1999, but the part itself is the 45RFE-family low/reverse one-way clutch, 4799465, listed for the 45RFE, 545RFE and 65RFE from 1999 up. The 45RFE and 545RFE share the same mechanical layout and differ mainly in software and the electronic fifth gear. Chrysler revised parts inside these units over the years, so before you order, match the number on your old part, its spline count and its outside diameter to this one. You can also send us your year and VIN and we will check it. This is not the heavy-duty 68RFE unit used behind the 6.7L Cummins. Other parts for this transmission are on our 545RFE parts page and the 45RFE parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The 45RFE, 545RFE and 65RFE are one transmission family, and this low/reverse one-way clutch (Chrysler 4799465) is listed for all three from 1999 up. Ours came out of a 2003 Ram 1500 45RFE.
Do not assume it will. The 68RFE behind the 6.7L Cummins uses its own heavy-duty low sprag. Compare part numbers and spline counts, or send us your VIN.
That is the classic sign. Low keeps the low/reverse clutch applied and covers for a slipping one-way clutch, while Drive relies on the one-way clutch alone in first gear.
Yes. Chrysler lists low fluid, a cracked primary filter or seal, low line pressure, and underdrive clutch seal or accumulator problems along with a failed overrunning clutch. Check those first.
ATF+4. Set the level with the transmission at operating temperature, then run the quick learn with a scan tool.
