Our 545RFE Updates and Upgrades

► Fully remanufactured valve body includes updated solenoid switch valves for improved shifting, lubrication, and performance.
► Fully remanufactured torque converter is tested for leaks, lockup, concentricity, and balance. Upgrades exceed OE requirements and eliminate the possibility of front seal leaks, premature bushing wear, and vibration.
► Completely remanufactured pump, complete with updated TCC limit valve and TCC accumulator to ensure proper TCC control and cooler flow, provides consistent internal pressures, eliminating slippage and delayed engagement.
► New line pressure sensor maintains consistent shift quality.
► Secured accumulator cover bolts prevent loss of 3rd or 4th gear.
► Fully remanufactured solenoid packs are tested separately from the transmission before dyno testing to verify shift quality and pressure control.
► All-new custom-spec bushings improve internal fluid flow control and pressures.
► Bushings and machined surfaces polished to a mirror-like OE finish of 16 RA or less.
► Complete system correction and recalibration kit installed to address several OE flaws. Modifications include updates to servos, the PR system, and valve body accumulators.
► Heavy-duty recalibration kit installed to reduce slippage and increase durability.
► Complete road simulation using a dynamometer testing program called C.A.R.S. (Computer Aided Road Simulation). Every transmission is cold and hot tested before shipment.

545RFE Vehicle Applications

How Many Variations of the 545RFE?

There are many different variations (so we have over 60 different part numbers!). Each one for a different engine size (bellhousing) and varying electronic and solenoid systems for different years.

Only certain models will interchange with others, which is why we ask for your 17-digit VIN# when you order so we are 100% sure it is the matching unit for your vehicle!

Remanufactured 545RFE vs. Rebuilt or Used

Reman 545RFE vs. Rebuilt 545RFE?
Both are good options but the best option for you depends on the transmission problem, the year, make and model of vehicle, the mileage and the vehicle value. What kind of warranty coverage are you looking for? Remanufactured transmissions carry a longer, 3 year, nationwide warranty with additional upgrades while a rebuilt unit generally carries up to a 1 or 2 year warranty and upgrades vary from shop to shop.
Reman 545RFE vs. Used 545RFE?
Buying a used 545RFE transmission may save you money. However, if the unit does not work properly after installed, you will more than likely have to pay the labor again for removal and reinstall of the transmission PLUS the freight to ship the transmission back to the salvage yard. The additional cost may be higher than installing a reman or rebuilt transmission–not to mention the extra downtime. Warranties for a used transmission is only 30 days, 60 days, 90 days or 6 months. Used transmissions, since there is no way to know how many miles are on them, may fail at any time.

545RFE and 45RFE History

Previously called the 45RFE which was introduced in the Jeep Grand Cherokee in 1999, it is notable for including three planetary gearsets rather than the two normally used in a 4-speed automatic.

It also features three multiple disc input clutches, three multiple disc holding clutches, and a dual internal filter system (one primary filter for transmission sump, one for the fluid cooler return system). In the 45RFE applications four gears are utilized, with a different (1.50:1 rather than 1.67:1) second gear to increase versatility when downshifting.

In 545RFE usage, an extra taller overdrive ratio is also used. Chrysler decided to refer to it as a “multi-speed automatic”.

The 45RFE was produced at the Indiana Transmission plant in Kokomo, Indiana. It was normally paired with the 4.7 L PowerTech V8. The 45RFE later became the 5-speed 545RFE
