Check the tech articles on this site. There's one that explains how to hook up a manual override switch for your converter lockup.

 

ok but i want to know how it works that the buick guys r doin it i want some info about it befor i go and try it

 

I've never tried it myself, but I think the basic theory behind it is that if you lock up the converter clutch early, you eliminate any slippage of the converter, which gives you a faster takeoff and shifts. I could be wrong though.
