| Chronology | |
| Successor | 6F |
The AXOD was a 4-speed automatic transaxle for transverse front wheel drive automobiles from the Ford Motor Company. It was introduced in the 1986 Ford Taurus/Mercury Sable (with the 3.0 L Vulcan V6). The AXOD and its successors are built in Ford's Van Dyke Transmission plant in Sterling Heights, Michigan. Production of the final member of the family, the 4F50N (a renaming of the AX4N), ended in November 2006.
The AXOD has a code letter of "T" on its data plate. The AXOD transaxle has 17 bolts to retain its fluid pan.
Applications:
The AXOD was updated with electronic controls in 1991 as the AXOD-E. The electronic shifting and torque converter controls were integrated with the Taurus's electronic control module for smoother shifts.
This had a data plate code of "T" for 1991 and 1992 models.
Applications:
The 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."
Applications:
The AX4N is an improved version of the basic AXOD, and is more reliable. This transaxle shifting is non-synchronous (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.The data plate code is "X."
