727 Kickdown Linkage Adjustment - HELP!

I have the same car and drivetrain combo. I used the second method.
At WOT, I adjusted the linkage at the carb to push the kickdown lever as far back as it would go. In Drive, my 1-2 shift at WOT is at about 4,000 rpm. Much lower than I want it to be. If I want it to shift at a higher RPM, I need to shift manually.

It is also very difficult to get a 2-1 down shift at anything over 15 mph unless I down shift manually. This is something I have been meaning to get to , but just havn't had time recently. There is also the band adjustment on the drivers side of the transmission. What does the service manual say about that? Does that need to be done first?
