Turbo 400 Kickdown??

[g356gear]

You should have (if it is a factory TH400 car) a little white attachment bolted to your pedal support bracket above your acceleration pedal. It has two wires coming from it and a spring loaded plunger. When you hit the throttle WOT, it sends a 12v signal to the solenoid mounted on the drivers side of the trans-this engages the solenoid, giving you kickdown. One of the wires goes to a 12v IGN. source in your fuse block, the other wire goes out to the trans lead terminal.

I checked tonight and no switch of any kind on the pedal. Everything is stock under there and the linkage comes straight of the pedal and through the firewall.
