545RFE Input Drum 1999-2007, used and ready to install. Fits the 545RFE. Ships fast from the USA.
Rebuilding a 1999-2007 545RFE or 45RFE and found the input drum unusable? This listing is a used Chrysler input clutch retainer of the early design, supplied with the reverse/overdrive piston that rides inside it, for Dodge and Jeep applications such as the Ram 1500, Dakota, Durango, Grand Cherokee and Liberty. Chrysler numbers 68009648AD and 68029262AA are listed for it. Choosing an early retainer matters when you want to keep the rest of an early unit as it came from the factory.
Engine torque comes off the converter on the input shaft and goes straight into this drum. Inside it, three driving clutches decide which member of the planetary gearsets that torque reaches next: underdrive for the low gears, overdrive for the high gears, and reverse for backing up. Per Chrysler's chart the 545RFE runs underdrive in first, second, second prime and third, overdrive in third through fifth, and both together in limp-in. Because the drum spins at input speed in every gear, a wobble, a worn bushing or a leaking seal ring land here costs apply pressure to all three clutches at once.
Start with fluid level and condition, then scan for line pressure and solenoid codes, because a bad pressure control solenoid or valve body can create slip in every gear too. If the unit is out, an air check shows whether the drum holds pressure: each circuit should apply firmly with no steady leak. Our 45RFE and 545RFE problems guide lays out which symptoms belong to which clutch, and the pressure control solenoid guide covers the line pressure faults to eliminate first.
The listing fits the 45RFE and 545RFE from 1999 to 2007. Sonnax documents two retainer designs: the 1999-2007 part measures 2.765 in. at dimension A and has a small chamfer, and the 2007-and-later part measures 2.825 in. with a large chamfer. This is the early one. Several aftermarket overdrive upgrades, including Sonnax's Smart-Tech housing, require the later retainer, so if you plan to install one of those, this drum is not the right base. TransGo also lists different underdrive and overdrive pressure plates by era, so keep the plates that match. If your truck is a 2007, measure the old drum or send us the year, model and VIN. Everything for this family is on the 45RFE and 545RFE collection page.
Pair the drum with the 45RFE overhaul kit for 1999-2005 for seals and gaskets, and inspect the front pump bushing while the unit is open; the 45RFE pump for 1999-2006 fits the same early units.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Early. It is listed for 1999-2007 and corresponds to the design Sonnax measures at 2.765 in. at dimension A with a small chamfer. The 2007-and-later version measures 2.825 in. with a large chamfer.
No. Sonnax states that kit requires the input clutch retainer from 2007-and-later units. Use a late retainer for that upgrade.
The underdrive, overdrive and reverse clutches. The 2C, 4C and low/reverse clutches are in the case, not in this drum.
Seal rings, piston seals, frictions and steels for the three packs, the filter, and the pump bushing if it shows wear. Check input shaft end play after assembly.
ATF+4 only. After the rebuild run the Quick Learn so the computer adapts to the new clutch clearances.
