The "why" is GM put a restriction in the factory line. When you are really using the clutch the fluid does not have time to flow back quick enough and sometimes cause a slow release. 1/8 drill bit, flush it out and you are golden. Aftermarket or home made lines do not have this line restriction. Took me maybe 10 minutes to do the entire modification.
