About Our Remanufactured 45RFE Transmission


Before you visited our site it’s possible you might have been considering a cheap 45RFE rebuilt transmission or thought about going with a complete DIY 45RFE transmission rebuild. Even though these options are often cheap, they are not going to last nearly as long as a remanufactured 45RFE transmission. If you want to get as many miles as possible out of your replacement 45RFE transmission, then a remanufactured 45RFE transmission is the way to go for your car or truck.

No matter what type of vehicle you own you should learn how a remanufactured 45RFE transmission works. When we get a 45RFE transmission that is broken down, the first thing we do is take it apart completely to individually inspect all the components from the supplier. Then, we replace every single component with re-machined or new parts. Afterwards, we compare every part and the transmission unit as a whole against the specification that has been set by the original equipment manufacturer (OEM). That way, we know the performance of every part in that transmission is going to meet or exceed your expectations.

A professional member of our team is responsible for ensuring the top quality of every 45RFE transmission for sale at Reman-Transmission. Because we correct any known factory defects in the remanufacturing process, our remanufactured 45RFE transmissions are among the best in the industry. That way, you can have supreme confidence in your vehicle when you return to the street. A remanufactured 45RFE transmission could last for hundreds of thousands of miles when cared for properly. As a more economical choice for our consumer, we also sell quality used 45RFE transmissions that are inspected to make sure they are in good working condition. We understand that not everyone who needs a 45RFE transmission replacement needs to go all out on a remanufactured unit, but at the same time, we do our best to ensure the used 45RFE transmission is of the highest quality.

We are so confident in the quality of our work that we even provide a warranty for every transmission that well. We also offer an up to 5-year, unlimited/ mileage warranty on most of our remanufactured automatic transmissions. Furthermore, we offer free-shipping to all commercial addresses in the United States as well as a waived core charge for 30-days to allow you the time you need for your 45RFE transmission swap. If you have any questions or need help finding the right transmission replacement option for you, don’t hesitate to give one of our friendly customer service representatives a call today!

Our 45RFE Transmission 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.

Every transmission is cold-and hot-tested using a proprietary dynamometer testing program that includes fully synthetic automatic transmission fluid and a filtration system.

45RFE Frequently Asked Questions

Yes, the 45RFE transmission is a solid transmission. Even though there are numerous successors that have been introduced, this transmission is still in use today because of its durability and longevity. If you want the best 45RFE transmission, then you should go with a remanufactured 45RFE transmission, as this has had all known factory defects corrected.

No, not every 45RFE transmission is the same. The 45RFE transmission was designed to fit the bellhousing of certain vehicles. It was used in multiple Jeep and Dodge vehicles in both 3.7 L and 4.7 L varieties. In addition, the 45RFE is also different from its counterpart the 545RFE transmission.

Shortly after the introduction of the 45RFE transmission, it was expanded to other vehicles. As a result, the 545RFE transmission was also introduced. A new gear was added for the 545RFE transmission. In addition, the gear ratio is different, expanding its versatility. We will make sure that the transmission we provide to you is compatible with the powertrain of your vehicle.

The 45RFE has been designed to hold approximately 8 quarts of fluid. If you drain the lines completely, your transmission may be able to hold a bit more fluid. We will let you know exactly how much transmission fluid your transmission requires. We will also make recommendations regarding the best transmission fluid product for your vehicle.

45RFE History & Information

The 45RFE transmission is made by Chrysler Corporation. The RFE stands for Rear Full Electronic meaning that the 45RFE transmission is specifically designed for vehicles that are rear-wheel drive and the system itself uses full electronic control for shifting. The 45RFE transmission is the first transmission in this family’s history, being used in many Jeep models starting in 1999. The 45RFE was mainly seen installed into production models like the Jeep Grand Cherokee, Jeep Liberty, Dodge Dakota, Dodge Durango, and a few Dodge Ram 1500 pickup truck models. Prior to the introduction of the Chrysler RFE class, TorqueFlite transmissions were used in the multitude of Chrysler vehicles for decades with a long history of success. The 45RFE transmission was designed to build on the success that was established by TorqueFlite.

One of the biggest changes the 45RFE transmission saw was that it had three separate gear sets instead of the two that were commonly found in its predecessors. After the 45RFE transmission was introduced, there were a few upgrades made. For example, the 45RFE transmission later became the 545RFE, meaning that it had five speeds instead of four. Other than that, the 545RFE transmission was relatively the same. Both the 45RFE and 545RFE were used in conjunction with the NV233D and NV244D transfer cases in 4x4 applications.

The 45RFE transmission received a significant amount of success in the automotive community. It was known for its power, longevity, and reliability; however, it was eventually phased out in favor of its successors. The 45RFE transmission was used all the way through 2002 before it evolved to the 545RFE, which was in use from 2001 to 2009. In 2007, the 68RFE was introduced for pickup trucks before it was expanded to other vehicles. In 2012, the 545RFE was recalibrated and gave rise to the 65RFE, which later undertook more upgrades and was dubbed the 66RFE transmission. 

Even though there are numerous new transmissions that have been introduced since the original introduction of the 45RFE transmission, the 45RFE transmission is still in use in numerous vehicles even to this day. This serves as a testament to its durability. On the other hand, every transmission including the 45RFE transmission can experience issues from time to time. If you are looking for a rebuilt 45RFE transmission or want to undergo a 45RFE transmission rebuild, you should first consider a used 45RFE transmission or remanufactured 45RFE transmission from Reman-Transmission.
