545RFE Solenoid Kit 2007-2011, remanufactured and ready to install. Fits the 545RFE. Ships fast from the USA.
A 2007-2011 Ram 1500, Durango, Aspen, Grand Cherokee or Commander with the five-speed 545RFE that suddenly holds second gear, flashes the check engine light and refuses to upshift is very often telling you about its solenoid pack. This listing is a remanufactured 545RFE solenoid pack for that 2007-2011 window, the assembly that bolts to the valve body under the pan and does every shift in the transmission.
The 545RFE is the five-speed member of Chrysler's RFE family, and Chrysler documents it together with the 45RFE in the same service information. Neither uses governor-driven shift valves. The controller applies the underdrive, overdrive, 2nd, 4th and low/reverse clutches by switching solenoids in the pack, and a pressure control solenoid regulates line pressure in a closed loop against a line pressure sensor. Pressure switches in the pack tell the controller each clutch circuit actually filled. The 545RFE also uses a second-prime ratio and a fifth gear that the four-speed calibration does not, so shift quality depends on every solenoid and switch in the pack responding cleanly. One shorted coil or a failed switch is enough to put the truck into its failsafe gear.
Chrysler also lists a solenoid switch valve latched code, P1776, in this family. That one points at the valve body rather than the pack, which is why diagnosis comes before parts.
Chrysler's service information calls a solenoid circuit code strictly an electrical fault, so start with the harness and the 23-pin case connector. Unplug it, check for bent or corroded pins, and measure each coil: Sonnax lists the shift solenoids at about 1.3 ohms and the pressure control solenoid at about 3.5 ohms. A coil far outside that range, or one shorted to ground, condemns the pack. Pressure switch and line pressure codes can come from low fluid or a leak, so check the level hot before blaming the pack. The RFE shift solenoid symptoms and testing guide covers the tests step by step, and 45RFE and 545RFE problems and fixes lists the other common failures.
The listing covers the 545RFE from 2007 through 2011, and that span crosses a design change. Sonnax reports the white-connector pack ran through 2009 and the gray-connector pack, with the overdrive solenoid deleted, arrived in 2010. Sonnax also notes the white pack could still service 2009-later units, while a gray pack cannot go back into an earlier six-solenoid transmission. The pack in the listing photo has a light-colored connector. Before ordering, look at the plug on your old pack and compare its color and part number, or send us your year and VIN so we can confirm it. All our RFE parts are on the 545RFE parts page.
If the pack tests good and the shifts are still poor, the problem is usually in the hydraulics. Compare a 545RFE valve body and read the RFE valve body testing guide first.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The listing covers 2007-2011, but 2010 began the gray-connector design. Sonnax notes a white-connector pack can service 2009-later units; compare your old pack's connector and part number or send us the VIN to confirm before ordering.
The 45RFE and 545RFE share the same RFE solenoid pack design and Chrysler covers them in the same service information. Match the connector color and part number to your old pack.
No. The pack bolts to the valve body and comes off once the pan, filter and internal connector are removed.
A pan filter and gasket at minimum, since the pan is already off. Use ATF+4 for the refill.
The controller still holds the old clutch fill values. Run the Quick Learn with a scan tool after installing the pack so it relearns them.
