Z1 Valve Body Upgrade
Has anybody heard about the Z1 Valve Body Upgrade? I was going to go with TransGo but since AMS installs the Z1 Valve Body Upgrade and they're only four hours away I was thinking of maybe driving my car to Toronto and having them do this for me, along with installing a GTM tranny cooler. So basically it's either TransGo or Z1. What do you guys think?
