so i had huge plans of upgrading to this industructable tranny in my truck, but now the budget reallllly doesnt allow for something that crazy, and i may have convinced myself to stay a lot closer to stock also. so if i were to get a tranny rebuilt, but still change a few things, what would those few things be? output shaft? convertor? what would i really need to run a downloader or somthing still, just not 2 of them and a turbo and all that other jazz?
