well i read it among
www.vehix.com and read their reviews and stuff about the 2000 mustangs and thats what it says so i am going by that and plus it also says on the peice of sticker on the side of my door inside and it says t-5 not sure if its tremec but it seems to be true when i look for a shifter for my car on steeda their steeda tri-ax short throw shifter for the t-5 transmission it says tremec on it but i am pretty sure i am right though but i could be wrong
