anyone else having problems with 2nd gear in thier 06's? I have been driving 5 speed mustangs forever and I can tell ya it ain't me. Anytime I try to even come close to a power shift with this thing it grinds second like an old T5 GRRR. It will do it on anything but a granny shift, I expect this on an old trans alot of passes on it but this thing is brand new! Suggestions?
