If my 727 shifts too soon, and too soft, which way do I adjust?

Maybe later if I can't get it back to where it was before. I doubt if there is any problem with the trans or the linkage. It was working good before I put the old carb back on. I appreciate the help & suggestions. Just working too much this week and have not had a chance to look at it again. Like here I am up at 3:30 AM getting ready to go to work. Aaaargh.

What is this work thing you speak of? I have never heard, used or done this term before.
