I have a 01 mustang gt and this is the year they had a half and mine is the 01 and 1/2 forward if thaqt makes any sense.Therefor i have the newer style transmission and i am having it rebuilt right now and first and second gear sync assembly is going to cost me $500.00! I called the parts store and can buy a trans for like $1100 but it isnt showing my trans anymore just one for that year and the same for the years after? mine is like a t3860 or something like that and the old one is a t5 and i was wandering if i could replace mine with a t5 please comment back soon.
