One problem related to transmission pump has been reported for the 1999 Ford Taurus. The most recently reported issues are listed below.
Got a transmission leak, the transmission pan seals were replaced as they were wet and transmission was flushed and refilled. Next day the car was still leaking transmission fluid brought it back to shop where the seals in the transmission pump were shredded. Was replaced and again transmission was flushed and filled. Get transmission back in car and o/d light is on. Replaced the cables and siliniod pack. Next day driving the car at 10 mph the car lost power and was like in neutral. Parked car and shut it off. Towed to mechanic and he said transmission is busted/broke and needs replacing.
