45RFE Master Rebuild Kit 2005, new and ready to install. Fits the 45RFE. Ships fast from the USA.
A 2005 four-speed 45RFE that has started slipping, shifting late, leaking from the pan and front seal, or going into limp mode on the way to work is usually a candidate for a full overhaul, not another fluid change. This 2005 master rebuild kit carries the parts that wear out in that teardown. In the listing photo you can see complete friction and steel packs, a sump filter, a smaller round filter that looks to be the cooler-return spin-on, the gasket set, rubber lip seals, O-rings and the metal and plastic sealing rings. Check the photo against what you pull out of your case.
Unlike the 46RE and 47RE that Chrysler built alongside it, the 45RFE uses no bands or servos. First gear is underdrive plus low/reverse, 2nd is underdrive plus 2C, 3rd is underdrive plus overdrive and 4th (0.75:1) is overdrive plus 4C. Because each shift hands torque from one clutch to the next, the controller learns a fill volume for every pack. When one pack wears, the others get blamed for slipping too, which is why a master kit with all six packs and a full seal set makes more sense than replacing a single drum's frictions.
Many 45RFE complaints start in the valve body and solenoid pack, not the clutches. A P0871 overdrive pressure switch code is most often worn solenoid switch valve bores, and a low line pressure code can be the pump. Before you order, read the 45RFE and 545RFE problems guide and run the checks in the 45RFE pump failure guide. If the pan shows clutch material along with those codes, plan to fix the valve body and pump in the same job.
This listing is for the 45RFE in 2005, and the same kit is sold for the 2005 545RFE because both share seals, gaskets and clutch hardware. A 2005 unit is the early seven check ball valve body design with a manual 2-L shifter range; GEARS Magazine notes Chrysler changed to a five-ball valve body and dropped the overdrive solenoid in 2009, so do not mix later valve body parts into this rebuild. Read the tag on the case to confirm you have a 45RFE and not a 42RLE or 46RE, and send us year and VIN if anything looks different from the photo. Other years are on the 45RFE collection page.
If the valve body is worn, the 2005 45RFE valve body goes in at the same time.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Mechanically they are nearly identical. The 545RFE adds a 5th gear and a 2nd prime ratio through programming. This kit is listed for both 2005 versions; the build tag on the case tells you which you have.
Not by itself. P0871 usually comes from worn solenoid switch valve bores in the valve body. If the clutches burned because of it, repair or replace the valve body in the same job or the new frictions will burn again.
If the pan has heavy clutch material, the fluid is burnt and you have ratio codes or slipping in 3rd and 4th, a fluid change will not fix it. Clean fluid with an electrical code points to the solenoid pack or sensors instead.
Mopar ATF+4 only. Fill to the hot mark on the dipstick after the rebuild and recheck after the first drive.
Only if it tests good. Clean it, check the solenoid switch valve bore for wear and keep the seven check ball 2005 design rather than swapping in a 2009 or later valve body.
