1970 Dodge Dart Swinger 340 - Kickdown setup help

This great basics and that is where I am. Wanting to clearly understand and probably falls under the stupid question! Should it down shift ONLY when the pedal is at the floor! I assume the process is: put it to the floor sort of quickly, it down shifts to 2nd get the pedal from the floor, than makes its way back up the gears as normal? Trying to understand the whole sequence. This is great stuff. Tranny is a Torqueflite 727. Thanks, Ron

The transmission downshifts two ways. Normally when coming to a stop and when the pedal is depressed. It might have the part throttle downshift unit on the valve body which will allow shifts at part throttle, otherwise you will see downshifts pretty close to full throttle.
