545RFE Sun Shell 1999-18, new and ready to install. Fits the 545RFE. Ships fast from the USA.
Before you order: this listing is filed under sun shell, but the part pictured and shipped is the TransGo SK 45RFE-A SHIFT KIT valve body repair kit, not a planetary sun shell. If your five-speed 545RFE Ram 1500, Durango, Dakota, Grand Cherokee or Commander slams into converter lockup, slides and then bumps on the apply, sets a converter clutch slip code, or falls into limp mode with P0868 line pressure low, this is the kit aimed at those complaints. TransGo lists it for 1999 through 2018 Chrysler, Dodge, Ram and Jeep vehicles with the 45RFE, 545RFE, 65RFE, 66RFE and 68RFE.
The 545RFE has no bands, no governor and no throttle cable. The transmission controller picks every gear by switching solenoids in the pack bolted to the valve body, and line pressure is set by a pressure control solenoid. So a kit for this unit is not about making shifts feel hard. It is about restoring the oil circuits the computer depends on. The single biggest target here is the torque converter limit valve in the pump. TransGo says the bore that valve rides in is often so worn on these units that the pump looks scrap. The kit supplies drop-in limit valve parts that work in both the early and late pump designs no matter how far the bore has worn, which can save buying a pump.
The second target is the converter clutch apply. The 545RFE uses its low/reverse solenoid twice: it feeds the low/reverse clutch in first gear, then a solenoid switch valve hands that same solenoid over to the converter clutch from second gear up. When the switch valve sticks or the TCC accumulator is out of calibration, lockup comes on rough or slips. The kit replaces the switch valve with a self-cleaning one and its end plug, and recalibrates the TCC accumulator.
Scan for codes first. Solenoid circuit codes are electrical faults and point at the pack or wiring, not at this kit. Pressure codes and TCC slip codes are where the kit earns its keep, but a line pressure gauge on the case ports tells you more than any code. If line pressure is low at idle and the pump gears are damaged, the pump needs replacing, not just the limit valve. Our 45RFE/545RFE valve body testing guide walks through separating valve body leaks from pump and solenoid faults, and the pump failure guide covers the low pressure and lockup symptoms that start in the pump.
The listing covers 1999 to 2018, which matches TransGo's coverage for the whole RFE family. The kit is the same part for the 45RFE and 545RFE; it is not a year-specific casting, but the pump it modifies did change from an early to a late design, and TransGo built the limit valve parts to cover both. If you are unsure which RFE you have, send us your year and VIN, or browse every part for this family on our 45RFE and 545RFE parts page.
This is a rebuild-bench kit. The pump has to come out for the limit valve, and the snap ring lives in the input drum, so plan to install it during an overhaul. Follow TransGo's printed instructions in order and keep the removed parts laid out. If the pump gears or stator are damaged, a replacement 545RFE pump is the better route, and a master rebuild kit covers the frictions, steels and seals you will be replacing anyway. Refill with ATF+4 only; Chrysler lists an overhaul fill of roughly 14 to 16 liters. Afterward, run the Quick Learn with a scan tool, since Chrysler calls for it after clutch, seal or valve body work.

No. The item shipped is the TransGo SK 45RFE-A valve body repair kit shown in the photo. If you need a planetary sun shell, contact us before ordering.
Yes. TransGo lists the SK 45RFE-A for 1999-2018 45RFE, 545RFE, 65RFE, 66RFE and 68RFE units, including early and late pump designs.
It targets the common hydraulic causes: a worn converter limit valve bore, a sticking low/reverse switch valve and TCC accumulator calibration. Rule out a failed converter and electrical faults first.
Not completely. The limit valve parts go in the pump and the snap ring goes in the input drum, so the full kit is meant for installation during a rebuild.
ATF+4 only. Run the Quick Learn procedure with a scan tool after the work so the controller relearns clutch fill.
