545RFE Pressure Control Solenoid, new and ready to install. Fits the 545RFE. Ships fast from the USA.
This listing is a Mopar fluid and filter service kit for the 545RFE, not a standalone solenoid. The photo shows seven quarts of Mopar ATF+4, a primary pan filter with its pickup tube, a spin-on cooler return filter and a tube of Mopar sealant. It is the kit to buy when a Ram, Durango, Dakota or Jeep with the 545RFE is due for service, when the fluid is dark or burnt, or when you are chasing line pressure codes and want to rule out the cheap causes first. It is also what you install alongside a solenoid pack or valve body so the new parts start on clean oil.
The 545RFE builds all of its line pressure electronically. A pressure control solenoid inside the solenoid pack works against the main regulator spring, a sensor reports what the pump is actually making, and the computer keeps adjusting the solenoid until actual matches target. That loop only works if the pump can draw clean fluid. The primary filter in the pan feeds the pump, and the spin-on filter cleans fluid coming back from the cooler. Chrysler's own P0868 line pressure low procedure lists a cracked, plugged or mis-installed primary filter and a loose cooler return spin-on filter as causes, right next to low fluid level. In other words, a tired filter can set the same code people blame on the solenoid.
Before buying a solenoid pack, check the fluid level hot with the engine running in Park, look at the condition of the fluid, and confirm the spin-on filter is tight. Then read desired and actual line pressure on a scan tool and compare them with a mechanical gauge. Our line pressure code and pressure control solenoid testing guide gives the procedure. If the pressure is still wrong with fresh fluid and filters, the problem is further in, and the 45RFE pump failure guide is the next stop.
The kit is listed for the 545RFE, and ATF+4 is the correct fluid for every 45RFE and 545RFE. The primary filter is the part to check: Chrysler used different pan filters across drive types and years, so compare the pickup tube length and shape in the photo with the filter in your pan, or send us your year, drive type and VIN and we will confirm it. Other parts for this transmission are on the 45RFE and 545RFE parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. Despite the listing title, this is a Mopar 545RFE fluid and filter service kit: ATF+4, a primary pan filter, a spin-on cooler return filter and sealant, as shown in the photo. On the 545RFE the pressure control solenoid is part of the solenoid pack.
Yes. Chrysler's P0868 line pressure low procedure lists a cracked, plugged or mis-installed primary filter and a loose spin-on cooler return filter as possible causes, along with low fluid level.
The ATF+4 suits every 45RFE and 545RFE. Pan filters vary by drive type and year, so match the pickup tube in the photo to yours, or send us your year, drive type and VIN.
It covers a pan drop and filter change, which only replaces part of the fluid. A full flush or a dry rebuilt unit needs more ATF+4 than this.
Not for a fluid and filter change alone. Chrysler lists the Quick Learn for jobs such as solenoid pack, valve body, clutch or transmission replacement.
