C6 kickdown adjustment
I backed the kick down stop all the way out of the way long ago when I had a carburetor problem and then I forgot all about it. What can I say? I was young once.
Slowed down in my old age and finally noticed when crawling up an incline I would like my C6 to down shift sooner. I might have a vacuum leak or modulator problem so I'll check that stuff out.
Is there a procedure to correctly adjust that kick down screw or is it simply a matter of personal preference affected by torque as the engine and tranny age?

They kickdown linkage you are talking about is mechanical only. When the throttle hits the linkage and pushes it far enough, the tranny will kick down into 2nd gear. So if you are pulling a hill, and don't push the accelerator down far enough to activate it, then it still will not kick down, no matter what the load on the engine. So it's a matter of adjusting the linkage so it will kick down at a certain spot on the accelerator pedal position.
The vacuum modulator and the governor inside the tranny control the shifting on all other situations.

Thanks Dave. I decided to experiment with the adjustable stop fully extended. It does kick down now. In addition, I felt that both second and third shift points moved to a lower RPM with a slight increase in torque; more peppy around town. I remember thinking the name kick-down must not fully describe its usage and that the vacuum modulator must work in conjunction with or reference the throttle position through that linkage. Perhaps I am imagining all that stuff. I really don't know very much about an automatic except that you can hold a mug of coffee in city traffic and the clutch never wears out.
