Joe,
Good memory. I have a small button on the front of the console tray that activates the kickdown switch when I press the button. The accelerator has to be slightly engaged for it to activate, but it works great. Gernold installed this when he installed the 3.27 rear end so that if I needed a lower gear, I would not have to shift the lever.
Best,
Tom
