Mark purchased his a torque converter from Yank Performance. Yank is one of my favorites and Dave at Yank is great to do business with. So needless to say I think Mark made a great decision choosing Yank. When installing you should ALWAYS install a transmission cooler. The addition of the cooler really helps keep transmission temps under control. Prolonging transmission life. So these are the mods we completed on Mark's G8. Have fun Mark!!!
