true....but, my logic was that if you limit how much you use your ability to manually shift, then you have a decreased chance of anything going wrong w/ the tranny. And about the D3 shifting, I have timeslips to prove that racing in D3 improves 1/4 mile time as opposed to D4.

So....my overall message simplified is to just be CAREFUL as to how much you manually shift and be SMART as to when you do it.
