parking on a steep incline), the pawl may break off or seize the gears so that either the vehicle rolls away, or when the owner starts the vehicle and attempts to put the vehicle in gear, they are unable to move the shift lever from Park. This creates a compound issue in which the shifter linkage or cable can break due to excess force. The vehicle's owner guide states the appropriate procedure is to engage the parking brake before shifting to Park, rather than relying on the pawl, as the pawl is a last line of defense to prevent the vehicle from moving unintentionally. If the parking pawl breaks off or bends, serious transaxle damage can occur.

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."

Failure of the "Neutral to Drive
Accumulator" causes hard shifts into a drive gear (R, OD, D, 1) from "N" or "P". This can become quite violent. Reasons for this part's failure: Piston stuck, or seals or springs damaged or missing. Correction for this problem: Check these parts for damage. Replace as

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

Other issues such as locking and/or breaking the parking "pawl" occurs in these transmissions primarily due to owner negligence in not operating the parking brake properly, or not using the parking brake at all. If the vehicle is allowed to "roll back" onto the pawl with heavy force (such as when

required (located inside the transaxle, recommended that a transmission shop do the repair, but a full rebuild of the transaxle is NOT required). In general, however, difficulty shifting from neutral to overdrive, OD to N, N to R, and R to N is most likely caused by a stretched shifter cable.

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
437:
Earlier AXOD and AXOD-E models have a poor reliability record due to internal lubrication problems. These were mostly remedied by 1995. These transaxles require fluid and filter changes every 30,000 miles to maximize service life.

Recently, NHTSA launched an investigation into the Ford
Freestar and Mercury Monterey due to numerous complaints with regard to the equipped 4F50N transmission. Although the investigation is centered on the
