545RFE Solenoid Kit 1999-2018, remanufactured and ready to install. Fits the 545RFE. Ships fast from the USA.
On a 545RFE five-speed the complaints that send owners looking for a solenoid pack are usually specific: the truck will not take 5th on the highway, it sets a pressure switch code and drops into a limp gear, or the converter will not lock and the engine runs higher rpm at cruise. This kit puts a remanufactured 545RFE solenoid pack together with the service parts you need while the pan is off. Shown in the listing photo: the pack with a black 23-pin pass-through connector, the sump filter, a spin-on cooler return filter and a pan gasket. A 1-year warranty is stated on the listing.
The 545RFE adds a 5th gear and a 2nd prime ratio to the four-speed 45RFE design, but the pack still does the same job: it holds every clutch solenoid, the pressure control solenoid and the pressure switches. One detail matters for diagnosis on this unit. Chrysler explains that the low/reverse solenoid works through the solenoid switch valve: in 1st gear the valve sends that oil to the low/reverse clutch, and in 2nd, 2nd prime, 3rd, 4th and 5th it sends it to the converter clutch, which the computer modulates until slip is within 60 rpm. So a weak low/reverse solenoid can show up as a converter problem, and a switch valve fault can show up as a lost gear after Reverse. Overdrive, 2nd and 4th are normally venting solenoids that must be energized to apply their clutches, per Sonnax, so an open coil in one of them takes away the gears that use it.
Separate electrical faults from hydraulic ones. A solenoid circuit code is electrical, and a meter on the 23-pin connector will usually confirm it. Pressure switch codes are harder: Chrysler sets them when a switch reads open or closed at the wrong time in a given gear, and its cause list for P0871 includes damaged No. 4 or No. 6 check balls, a cut overdrive/reverse piston seal and broken reaction shaft support seal rings, not just the pack. Check fluid level and line pressure, and if clutch debris is in the pan, plan for internal work. Our 45RFE/545RFE valve body testing guide and 3-4 clutch failure guide walk through both sides.
The listing range is 545RFE 1999-2018, but the pack pictured uses the black pass-through connector. Transmission Digest describes the black-connector pack as the first design and notes the switch to a white connector in 2004, which then continued in the 45RFE and 545RFE. Before ordering, pull the pan or look at the connector where the harness enters the case and compare it to the photo. A white or gray plug means this pack may not match your transmission; send us the year, model and VIN and we will check it, or browse the other versions in the 45RFE and 545RFE collection.
Drain the 545RFE, remove the pan and sump filter, disconnect the case connector and unbolt the pack. Support the valve body so its check balls stay in place, then fit the new pack and torque the bolts evenly. Install the new sump filter and spin-on cooler return filter, seal the pan with the supplied gasket and refill with ATF+4. Finish with a Quick Learn on a scan tool. If you are replacing a worn casting at the same time, the 545RFE valve body is listed separately, and an aluminum 545RFE pan with a magnetic drain plug makes the next fluid change easier.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The 45RFE and 545RFE share the same pack design within each connector generation. What matters is matching the connector color and part number on your old pack, not just the transmission name.
It can be, since the overdrive and 4th clutch solenoids are normally venting and must be energized to apply. An open coil or a pressure switch fault will take those gears away. Read the codes and meter the pack, and check for overdrive clutch damage if P0871 is present.
The listing photo shows the remanufactured solenoid pack with a black connector, a sump filter, a spin-on cooler return filter and a pan gasket. ATF+4 is sold separately.
Yes. On the 545RFE the low/reverse solenoid also applies the converter clutch in 2nd through 5th through the solenoid switch valve, so a weak solenoid or a stuck switch valve can show up as no lockup or a P1776 code.
Refill and check the ATF+4 level hot, clear codes, and run Chrysler's Quick Learn with a scan tool so the computer relearns clutch fill times.
Do not assume so. Send us your year, model and VIN before ordering and we will confirm whether this pack or a different version matches.
