you just about have to upgrade tranny parts stock...your not going to go turbo for 600 dollars...unless you have extremely good resources and can weld all the hot side parts yourself. even then, anymore power and that tranny is going bye bye on your ass
how much do u think it would cost to upgrade the stock tranny parts?
