Mine sounds like a rock crusher at times,mainly at a light cruise,about 40 mph. When you get a load on it,it quiets down. 2nd gear is really notchy when cold. I now have 4400 miles on it.My old T-5s never sounded like that and the tranny,T-45,in my son's '01 V6 Stang doesn't do that either. How about anyone else? I did notice that on the tailshaft housing,of the V6 Stang trans,while swapping shifters,there is a small pair of those"monkey nuts".
