i have the a4 on my 98 z28 and know that the tranny is limiting my potential at the track. I was wondering what the best route/parts are to build it up so it can take the power i plan on giving to it. I know there are shift kits, but would that really be enough if i plan on using nitrous? I'd rather spend money now to build it up, then spend money later on fixing it, if it breaks. Someone said something about a valve body, or something along those lines. What exactly is that?
