Alright, I installed the Transmission Performance Button in my 95 camaro thanks to shoebox's website, but now I need to get a mail order tune for my new wheels. I plan on going with pcmforless and noticed that they can alter my transmission for harder shifts. Will this computer tuning modification in conjunction with my trans performance button cause any harm? How hard will this thing really shift? I understand that both the tuning and the button increase line pressure, but when is it too much? I just don't want to break anything!

Since you now have the switch working, consider having them program only the normal mode or performance mode tables, so that you can switch between them. Have one "mild" and the other more aggressive or "street" and "track" (or whatever you want to do). I doubt they will make any changes on their own that will do harm to your tranny. If you have specific needs, talk to your programmer about them.
