the problem that i cannot justify with built transmission is that they are meant to be rebuilt a lot more often.
?????? Where did you get this idea? If it needs rebuilt more often then it wasnt built right. Stock transmissions were designed for smooth shifts and stock power, not modded cars. Any car with more power than stock is going to make shorter life of a transmission. RACE transmissions will require being gone through more often because of how they are built, not all performance transmissions. Dynotech uses Borg Warner frictions other than 3rd gear which I assume is a Zpack but it doesnt say so I cant verify, but the BW friction plates are OE clutches and last a very long time. Hardparts are hardparts, there is nothing that needs serviced with them as they last or they break and that is just part of adding more power and the acceptance you take when adding more power.
