how can you tell between an AOD and T-5?

You can buy a "Super Duty" T-5 from Jegs. And a PRO 5.0 will fit the regular T-5, and the T-5z. It just depends on what your goals are for the car. If you want to go 11's or less, or run at the track all the time on slicks, you might want to check into a TKO II, or something of that nature.
