How much hp will the stock A4 trans handle safely in a 99 Z28?? I'm lookin to eventually get 400 horses to the wheels and I don't want to blow up my stock trans in the process.

GM rates at 375 personally I would always consider the trans and intrical part of the build up

Definitely. I was just trying to figure out which direction I wanted to go first as far as performance mods go.
