Remanufactured AX4N / 4R50N Transmissions 

Ship Direct To Repair Shop
We provide an out-the-door price, with shipping, for a replacement remanufactured AX4N transmission direct to the repair shop.
Reman AX4N vs. Rebuilt AX4N?
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 AX4N vs. Used AX4N?
Buying a used AX4S / AX4N 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.

What You Get With Every AX4N / 4F50N Transmission:

he AXOD-E was renamed AX4S in 1993. In addition to the name change, improvements in the lubrication of the gearset and capacity upgrades were made. A centrifugal piston assembly was implemented in the intermediate clutch position to improve 1st–2nd and 2nd–1st shift quality and an increase in the clutch's durability was made on some models. High energy friction materials were also introduced. A new twin piston torque converter clutch (TCC) was introduced with the AX4S and the AX4N on some models. The transaxle pan on this model will sometimes read "AXOD Metric" since it is based on the AXOD transaxle. The data plate code for this transmission is "L."

The AX4N is an improved version of the basic AXOD, and is more reliable. This transaxle shifting is non-sequential (as indicated by the "N" in AX4N) and has improved shift quality over the previous AX4S. Although similar in design and dimensions, it is a different transaxle than previous AXOD transmissions. The AX4N has 19 bolts to retain the fluid pan. It was used in the 1996–99 Taurus SHO models, and was standard on Duratec-powered models. It also appears in some 1994–2002 Vulcan-powered models. It became standard with both engines in 2003. It was renamed the 4F50N in 2001.

AX Series History:

How Many Variations of the AX4S/N/4F50N?

There are over 10 different variations (so we have over 10 different part numbers!).

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 pump, with new line bore bushings to eliminate leaks and provide superior flow and durability.
► Remanufactured valve body, with complete system correction and recalibration kit, improves pressure control and shift quality.
► Remanufactured and improved torque converter tested for leaks, concentricity, and balance. Upgrades exceed OE requirements and eliminate the possibilities of front seal leaks, premature bushing wear, and vibration.
► All new, bushings installed in key locations to improve internal fluid flow control and fluid pressures.
► 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.
