Joey,
Actually, it's 1-
D-1 shifting. Most people warn against it, saying it will shorten your tranny life...and it probably will. I only use it when racing or at the track. When you shift up from 1 to D, let the tranny complete the shift fully before you pull it back into 1.
As for when to shift, it depends on where you make power. For a near stock application, I would say move the shifter at around 4800-5000 rpm. It takes a second to actually shift, so this puts your shift point at or just under 5500 rpm.
