What Usually Causes The Transmission In A Ford Windstar Lx 2001 To End Upthiswa

Intermediate clutch failures resulting in poor 1–2 shifts or slipping are common on all AX family members.

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 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.

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 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.

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 Torque Converter, these failures often require that the entire transaxle be rebuilt or replaced.
