trans is going to shift early, no mater what you do the kickdown linkage does almost nothing for shift points if its on and somewhat close to the right adjustment, the governor is what needs to be changed

With the throttle at WOT, how much farther can you push the kickdown lever by hand? There should only be ~1/8" left, IIRC.
If you ever find yourself in a fair fight, your tactics suck.

Kickdown linkage adjustment does alot to shift points. It raises or lowers trans throttle press which will act on one side of the shift valve against Gov press on the other side. So if you raise the throttle press (lenthen rod) you will raise the shift points because now you need more gov pres to move the shift valve over which means you need more road speed which will give more gov press and raise the speed of the shift points.

I'm playing around with the kickdown, i made linkage rod at trans wayyy shorter, took it out and it still seems like it gets to 3rd gear way to fast, 1-2 and 2-3 I am TRYING to watch on the tact, and by sound/feel, I just can barely feel 1-2, 2-3 seems non-existant, yet when i slow down, i pop it manually into 2nd, it goes to second, telling me I was indeed in 3rd gear.
hate to screw my transmission up but what else do i do here?

Thats what I thought Stumpy, but after i put the adjuster on the very tip pf the rod, it was still doing all it's shifting early. Does the fact I have 3.55's change my perception of what I was used to with 2.94 on another car?
Duh

Just easy cruising, yes. If you have your foot in the pedal, no.
And the MOST adjusting of the shift points (via the throttle pressure linkage/lever) is when the lever is at the end of its travel when the throttle is wide open.
Once you've done that, the tranny will shift as late (higher RPM) that the lever will allow. To make further adjustments require internal mods/adjustments.
Simple as that.
Now you can drill a new hole in the lever (closer to its center-point) which will give more lever-travel per a given amount of travel of throttle. That will change the part throttle shifts but the wide open maximum adjustment available is still at the extreme travel of lever.
