545RFE Solenoid Kit 2004-09, new and ready to install. Fits the 545RFE. Ships fast from the USA.
On 2004 through 2009 Dodge and Jeep trucks and SUVs built with the 545RFE five-speed, a solenoid pack that is starting to fail usually announces itself with a line pressure code, a sudden drop into limp mode, or shifts that turn harsh once the transmission is hot. This kit is a factory-boxed solenoid pack for that 2004-2009 window. The product photo shows the pack in its Mopar carton alongside a pan filter, a canister style cooler return filter and a pan gasket; look at the photo to confirm the contents match what you want.
In these years the 545RFE pack still carries the full set of clutch solenoids, including the overdrive solenoid that Sonnax says Chrysler deleted from the 2010 and later pack. It also holds the variable force pressure control solenoid that sets line pressure. Chrysler runs line pressure in a closed loop on this unit: the computer reads a line pressure sensor and adjusts the pressure control solenoid duty cycle to hit a target that rises and falls with engine torque. Chrysler's diagnostic notes that a low duty cycle commands maximum pressure and a high one commands minimum, so a pressure control solenoid that sticks or leaks inside the pack shows up as a line pressure code long before any clutch is damaged. Everything else in the pack, the clutch solenoids and the pressure switches, decides which of the five forward ratios and the 2nd prime ratio is applied.
A line pressure code does not automatically mean a bad pack. Chrysler's P0868 and P0869 procedure has the tech compare desired and actual line pressure on a scan tool, then confirm with a mechanical gauge, because a weak pump, a stuck regulator valve or a failing line pressure sensor can set the same codes. Our 545RFE pressure control solenoid and line pressure guide lays out that test with the gauge ports and the pressure numbers. If the codes are solenoid circuit codes instead, use the resistance checks in the shift solenoid testing guide. A pack that measures right but still sets codes sends you to the wider list of 545RFE problems.
The listing is for the 545RFE in model years 2004 through 2009. Chrysler made running changes even inside that window, and a 545RFE truck and a 45RFE truck of the same year can look identical from the outside, so read the transmission tag or send us your year and VIN before ordering. Also check that the connector and screw pattern on your old pack match the photo. If your vehicle is a 2010 or later model, this pack is not the one for you. Every other part for this transmission family is on the 45RFE / 545RFE collection page.
If a pressure gauge shows low pressure with a good pack, the pump or valve body is next; a remanufactured 545RFE valve body and the 545RFE Banner rebuild kit cover those repairs.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It will if the pressure control solenoid in the pack is the cause. Confirm first by comparing desired and actual line pressure on a scan tool and with a gauge; a worn pump, regulator valve or line pressure sensor can set the same codes.
No. This listing covers 2004-2009. The later pack dropped the overdrive solenoid, so a 2010 or newer vehicle needs the later version. Send us your year and VIN if you are not sure.
It is listed as an OEM part, and the product photo shows the pack in its Mopar carton. Compare it with your original pack when it arrives.
Refill with ATF+4, then clear codes and run the Quick Learn with a scan tool. Drive until the fluid is fully warm before judging shift quality.
The pan filter, cooler return filter and pan gasket shown in the kit. If the old fluid is burnt or the pressure test shows low pressure, budget for the pump or valve body as well.
