I have a 05 v6 stang, and at 12,000 mile the tranny is making a noise when in reverse. Sounds like a hissing sound almost like there is an air leak somewhere. Has anyne run across this problem? I also have a problem when shifting from park to reverse, and it takes a few seconds to actually lock into gear, and when i slow down, and hit gas again it seems like it slips before it catches. The Ford dealer says it is all norma, and not to worry about it. Any help would be great. I am new to the forum, and is great Thanks in advance.
