Here's what I found...With key on, checked for voltage in wire that connects to throttle activated kick down switch and it was good. Checked switch for continuity with accelerator pedal to the floor and the switch was open. Removed switch and bench test showed that it remained open to within 5/16" of full travel. Thinking it was probably dirty, sprayed it liberally with contact cleaner and worked it vigorously but to no avail. Found a piece of round hard plastic 11/16" OD and drilled it to 3/8" ID for a press fit over the arm of the switch. Re-installed and test drive shows proper kick down function. Good for now. Thanks again for taking time to respond and sharing your knowledge!
