Thanks for looking, this ought to be a simple question, but my 1967 FSM hasn't solved the problem... I'm referencing Fig 14 on page 21-49.

The car is a 1967 Satellite stock 2bbl 383 with a 1971 replacement 727-B column shift transmission with partial throttle kick down.

Question I have is where to start when I adjust the slotted 'kick down' linkage bar at the carburetor that links back to the transmission's shift lever?
Or maybe the better question is - what position should the 'kick down' lever at the 1971 transmission start at, when I set up the slotted end of the kick down bar at the carburetor that I'm pointing to in the picture below?

The 1967 FSM says to start with the transmission 'kick down' lever in the Full Forward position. OK.
But when I follow the rest of the 1967 FSM instructions and drive the car, the tranny shifts right through 2nd & 3rd at really low speeds, like 35mph.
I'm thinking I've got to start with that 'kick down' shift lever positioned further back on the 1971 tranny?

The picture is the current setup. My finger is pointing to the slotted end that I'm adjusting to just barely touch the throttle pin when the carb is a hot idle. In the picture I have shortened it a little to see if it makes a difference.

What I think I have to do is adjust the linkage from the rear bell crank down to the transmission such that the transmission 'kickdown' lever starts further back when the carb is at idle.
Am I on the right track?

Thanks for input.
