My wife's '89 Grand Prix has a TH440 with a vaccuum modulator. Which direction should I turn the screw to smooth out the shifts? Right now they're very hard and late... Clockwise or counter clockwise to smooth it out and make the shift a little earlier? Thanks y'all! Ratch <a target="_blank" href=http://k5.8m.com>k5.8m.com</a> Welcome to America.
