545RFE Sun Shell 2004-2014, new and ready to install. Fits the 545RFE. Ships fast from the USA.
The catalog name on this page reads sun shell, but the part that ships is a new Transtec overhaul kit (maker part DP2506) for the five-speed 545RFE, also sold as the 5-45RFE, in the 2004-2014 window the listing covers. It is the seal set for the Ram 1500, Durango, Dakota, Grand Cherokee or Commander that slips once it is hot, takes a second to engage after sitting overnight, or leaks no matter how many times the pan is resealed. There is no planetary gearset, shell or drum in the box. Buy it when the transmission is coming out for a rebuild and every rubber and Teflon seal needs to be new.
The 545RFE moves through its five forward gears and the 2nd prime ratio using six clutches and no bands. Three of those clutches rotate inside the input clutch housing, so their apply oil has to cross from the stationary pump and reaction shaft support into a spinning drum. Sealing rings carry that oil across the gap, piston lip seals trap it behind each clutch, and Teflon rings on the accumulator pistons keep the shift cushion working. The transmission controller then reads its pressure switches and speed sensors to decide whether each clutch applied on time. When years of heat harden those seals, oil bleeds off, the clutch fills late, and the controller keeps lengthening fill time until it gives up and sets a code. According to the listing, this kit contains all clutch drum piston lip seals, a full set of sealing rings, Teflon accumulator piston rings, metal-clad seals and O-rings, with the gaskets shown in the photo.
Rebuild seals are the answer once the unit is out, not a first guess on a truck that still drives. Check fluid level hot, then compare commanded and actual line pressure; the 45RFE line pressure and pressure control solenoid guide covers P0868 and P0869 and what each reading means. A worn pump gives the same low numbers as leaking rings, so read the pump failure guide before you decide. If the codes point at a pressure switch, the valve body testing guide shows how a worn switch valve bore fakes a sealing problem.
The listing gives two ranges, and buyers should know both. The title covers 2004-2014 545RFE and 65RFE, while the kit text describes it as a 5-45RFE kit for 2006-2011. Treat a 2006-up five-speed as the core fit. If you own a 2004 or 2005 truck, or a four-speed 45RFE, pull one piston seal and one sealing ring and compare them with the photo, or send us your year and VIN before ordering, because seal sizes changed during production. The 45RFE and 545RFE parts page lists the kits for other years.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The catalog name is wrong. The part shipped is a new Transtec 545RFE overhaul kit with seals, sealing rings, O-rings and gaskets, as shown in the photo.
No. It is a soft-parts kit only. Frictions and steels are sold separately or as part of a master rebuild kit.
The listing title covers 2004-2014, but the kit text is written for 2006-2011 units. Compare a removed seal and sealing ring with the photo, or send us your VIN and we will confirm before you order.
ATF+4 only. Chrysler lists 14 to 16 liters for an overhaul fill. Check the final level hot with the engine running.
Yes. Chrysler lists seal replacement as a reason to run the Quick Learn procedure with a scan tool before the road test.
