Assuming you have an adjustable modulator you use a small screw driver and turn the screw that is inside the vacuum fitting. Make small adjustments at a time.

ok well i got that part but what i meant was what happens to the shifting when i turn th screw in? out? thanks
Can't remember which is which but one way will make the shift later firmer and the other will make it earlier and softer.
in ----out....
Turning the adjusting screw IN makes it shift a bit harder and later..turning it OUT makes it shift softer and earlier...you'll only get a range of about 10-15 mph difference at what speed it shifts at,and only a firm shift if you crank it IN ,there isn't a huge difference really..
I read your other post...sorry its the direct clutch,I was hoping it was something easy and cheap for you to fix..
