I'm no expert either, but have taken a few ATs apart.  cv joint angles: how
much difference is there between the current location and the stock
location?  Not much I bet.  How is the front trans mount handling the
stress of this new angle, or was it modified?  Fluid levels would be
affected.  The AT's pickup is toward the front of the pan.  Oil level in
the final drive might be affected.  Seals at the joining of the trans and
final drive and at the rear of the final drive might not drain properly at
this angle.  As you see, I have no answers, only things to think about!
