I have a 2003 Taurus with the 3.0 liter Vulcan V-6 with 75,000 miles. I purchased the car used and changed the transmission fluid right away with Mercon V (about 10,000 miles ago). Twice in the last two months it has left a puddle of transmission fluid in the driveway. Im not sure if this happens at shut down or startup. According to the dipstick the transmission is not overfilled. Does anyone have a clue as to what might cause the transmission to puke like this?
