I believe that its a T 45, not T 5 they came on V6s in that year.I believe that the 3650 is stronger than the T45, but people seem to have less shifting problems with the T 45, and as for performance you should be OK, unless you slap on a SC then you would probably be better off buying the TKO so you KNOW that it will hold up and not give up...if I am wrong please correct me LOL.
