904 Valve Body

So I called the TransGo tech today and he said to put a gauge on the accumulator port and with the car on jackstands, put it in drive and move the kickdown rod towards the firewall slowly. When the pressure starts to rise, mark that point somewhere on the linkage and the trans.
Thats where carb stud and the backside of the slotted kickdown adjuster go together.
The problem now is the trans kickdown stops the throttle from achiving wot.
How can I fix the linkage? Making it longer won't do it.
Thanks for any help.
