Shift kits.. do you really need one????

Wow as someone who has only built one trans, a 904 built to handle the 524 hp 527ftlbs it sits behind I have to say I was really looking forward to an intelligent discussion.I have been going back and forth with the idea of putting in either a tf2 kit or a Cheetah prostreet auto valve body which is supposed to be designed to do all the things you would get from a kit in a stock valve body . There were 3 people whose help was crucial when I was building my trans and you Bakerlite have **** on or ignored 2 of them , atta boy , no wonder the third has remained on the sidelines , perhaps you should try engaging people if you want them to expound on their posts further .
