Cool. Although I won't be doing any racing (To damn old) I know others would like to beef up the trans for racing and towing. From what I understand, which isn't much, faster/harder shifts actually prevent clutch slipping and helps transmission life. Am I on the right track here?

To a point you are correct, Most people go WAY overboard, Like the guy in the video Blocking the Line Bias valve & running a larger Boost Valve. Block the Bias & run a .500 Boost valve....You WILL break $hit, I promise

The Line Bias valve is used to match the Line Pressure Rise to the Torque Rise of the engine as a Variable Bleed & as a Safety Blow-off if the TV valve sticks. The TV Boost valve size controls overall clutch line pressure in proportion to TV valve movement. I guess its a short cut around actually tuning the line bias in with heavier spring/s to match.

What sky high line pressure does to a 2-4 band at a WOT 1-2 shift behind a ZZ430.....
