45RFE / 545RFE / 65RFE Master Rebuild Kit with 4WD Filter

This is the full soft-parts master kit for rebuilding the Chrysler 45RFE five-speed and its later 545RFE and 65RFE variants, the automatic behind the 3.7, 4.7, 5.7 and diesel engines in a huge run of Ram, Dodge and Jeep trucks and SUVs. It carries the friction plates, steel plates, gaskets, rubber and Teflon sealing rings, O-rings, bushings and the 4WD-length filter you need to put the unit back together in one box, so you are not chasing a missing seal halfway through the job.

Fitment is broad: Chrysler Aspen 2007-2009, Dodge Dakota 2000-2011, Durango 1999-2018, Ram 1500 2002-2018 and Ram 2500/3500 2002-2016, plus Jeep Cherokee, Commander, Grand Cherokee 1999-2013, Liberty and Wrangler, and the Mitsubishi Raider. It covers rear-wheel, four-wheel and all-wheel drive versions of the transmission. Because Chrysler ran 45RFE, 545RFE and 65RFE hardware across overlapping years, confirm your exact case and filter length against your VIN before you order.

Use it on a full overhaul: strip the transmission down, wash every part, replace all the frictions and steels, install the new gaskets and lip seals, resize the Teflon rings on the drums and pump, drop in the new filter, and set clutch clearances to spec as you stack the units. These transmissions are known for burning the overdrive and reverse clutches and for solenoid and pressure-transducer trouble, so a clutch-and-seal rebuild with fresh fluid is the standard fix when one starts slipping, flaring on the shift, or dropping out of gear.

Kit weighs about 14.5 lb shipped. Frictions and steels are the wear items in one of these units, so replacing the complete pack rather than reusing burnt plates is what keeps the rebuild from coming back apart. Ships from the USA, handling in 1-2 business days.
