I had the fluid change TSB done on my 2011 GT by the Ford dealership close to where I work. They are a small dealer and don't sell many Mustangs. I think mine is their first experience with MT82 problems. My problem is grinding on the 1 to 2 shift and the 2 to 3 shift when cold. The fluid change helped some but it still grinds until the transmission warms up. Once warm it is just notchy in every gear. What else can I suggest they try to fix this problem? I only have 10,000 left on my warranty to I'd like to get it fixed the best I can before it runs out. Thanks for your help!
