Using the TransGo Separator Plate, with a Corvette 2nd Servo Piston and a .500 Boost Valve..

Transgo says that with the bigger 2nd Piston, drill passages A and C to between .093" to .110".

I understand the Corvette servo can give rough 1-2 shifts, would drilling these to the smaller end of the scale keep the shifting from being too harsh?

Also, I think that passage A = 3rd gear Apply and C = 2nd gear apply, can anybody confirm that?
