Two automatic overdrive transmissions were used in the V8 4.7 L Grand Cherokee. The 45RFE is a 4 forward speed automatic overdrive transmission. First introduced to the Grand Cherokee in 1999. When our customer called for a Grand Cherokee 4WD V8 4.7 Auto Reman Transmission for sale, all we needed to know were a few digits from the VIN [vehicle identification number] to figure out which remanufactured transmission to offer.
The other model, 545RFE is a 5 speed automatic overdrive transmission and was introduced to the lineup in 2001 in the Jeep Grand Cherokee, Jeep Liberty, and many Dodge products as it is a Chrysler transmission. Both use an energy efficient lock up torque converter.
Both transmissions are considered to be very heavy duty. Each one is fully computerized. Seemingly having a mind of it’s own to control how it shifts and when it shifts, almost with out effort. It never ceases to amaze me at how much an automatic transmission reminds me of the human brain.
I want to add that these transmissions will fit rear wheel drive vehicles only, commonly called a longitudinal design by automotive experts. Wiki refers to it as a F/R or front engine, rear drive setup.
I recommend to most people that a remanufactured replacement transmission is the most cost effective and ultimately affordable transmission in the long run. Especially when you consider our remanufactured transmissions are fully updated with the latest and most effective updates on the market.
