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?
Post a pic of your instruction sheet!

2nd apply with a 093 piston & stock converter......No bigger than .076".

3rd & 4th apply are good at .110"

A .500" TV Boost is dangerous territory for stock Cast Pump Rings!!
