School me on the 72 Formula kickdown switch.
Guys, my 72 Formy kick down function is inop. I have no manual to tell me how it works and the location of the controlling components. Can one of you Geniuses on PY give me a lesson on how this system works and the location of the related components? The car is stock, as far as I know. It did go through a restoration so I suspect it was not properly installed. Car is a 400 w/TH400. Sure would appreciate the help.

Does it have the kick down slider switch mounted just above/behind the accelerator pedal with the wire connector plugged in? The wires run to the kick down solenoid in the driver's side of the transmission, plugs in just in front of the speedo cable/gear housing. If that is all plugged in, the first thing I would try is to adjust the kick down switch at the pedal. The switch at the pedal has a tang on it that you can depress to allow the slider to go all the way forward. Then pull the slider back just enough for the tang to pop up and engage. The next time you floor it, it should adjust itself to the correct position. Let us know what you have in place on your car.

Here it is in its place. (The orange and pink, two-wire connector hanging next to the steering column should be connected to it - this was the original photo of my 19,000 mile car when I was doing the heater core - I found that the two-wire harness had never been connected to the switch! I hooked it up and the transmission worked a little better)

If you find the wiring and switch are good the problem is likely the solenoid within the transmission. Not hard to replace but messy.
