Ford Automatic 4 speed
Thank you for contacting the Center for Auto Safety (CAS) about the AXOD, AXOD-E, AX4S or AX4N automatic transmission in your vehicle. One or another of these transmissions are used in many vehicles including the Taurus, Sable, Windstar, and Continental. CAS has received numerous complaints on chronic stalling, slippage, harsh or erratic shifting, hesitation, and/or sudden failure.
The AXO, AXOD-E automatic 4-speed overdrive transmission has been plagued with performance problems since its introduction in 1986. The transmissions in the 1991 Taurus/Sable and Continental are especially prone to erratic operation, overheating and/or sudden failure. A 1995 survey by Consumer Reports found that nearly 20 percent of the owners of the 1991 Taurus/Sable and Continental had experienced a serious transmission problem in the preceding 12 months, four times the average problem rate for automatic transmissions in all 1991 vehicles.
Geartrain meltdown due to an inadequate supply of pressurized lubricating oil is one of the primary causes of transmission failure in vehicles built prior to 1993. Independent transmission shops typically address the inherent design defect in the AXO, AXOD-E transmission by enlarging the orifice which feeds the lube oil and making sure that the bushings, which help control the oil flow, are replaced if the least bit worn. In mid-1992, Ford redesigned the tubes above the oil filter and sent its dealers a service bulletin that attributed geartrain meltdown in all vehicles built in 1991 to a faulty gasket (TSB 92-26A-12). In July 1995, Ford extended the warranty on the automatic transmissions in all 1991 Tauruses/Sables and Continentals to six years/60,000 miles (Owner Notification Program 94M84). Owners complain Ford limits the program to only one free repair attempt, so make sure your first repair is a new transmission.
Cracks in the forward clutch piston is another notorious problem with the AXO, AXOD-E transmission from 1986 through 1995. These cracks cause the forward clutch to disengage, making the transmission feel as though it is in "neutral." In 1995, Ford began making the piston out of steel rather than aluminum to eliminate the cracking problem. To avoid costly repairs, mechanics recommend that the steel piston be installed in the forward clutch drum (refer to TSB 94-24-7) when any internal transmission work is performed.
