One commonly reported problem with Ford Taurus transmissions is transmission failure. Transmission leaks, shifting issues and slipping between gears have also been reported by owners. The most common transmission issues vary based on the year.
Transmission failure is reported often for the 2003 and 2005 model years. According to owner reports on CarComplaints.com, transmission failure occurred on average at 79,751 miles for the 2005 Ford Taurus and 93,201 miles for the 2003 Ford Taurus. The average repair cost was around $2,000 in both cases.
The 2013 Ford Taurus has several minor transmission issues reported. These include the transmission keeping the car in a higher gear when approaching a corner, going through several gears on hilly roads and stair stepping several gears when accelerating rapidly. The car has a sports mode, but it doesn't alleviate the issues. The transmission problems are less noticeable on the model with a V6 engine.
Ford's AXOD transmission and its successors were used in the Ford Taurus from 1986 until 2007. The early models had a problem with internal lubrication, causing them to be unreliable. The Neutral to Drive Accumulator could also fail, which caused the car to roughly shift into a driving gear from neutral or park. Causes of the part's failure include seals or springs that are missing, or a stuck piston.
