Many thanks XK Racer.
Wikipedia explanation.
Kick down switch
One of the most common inputs into a TCU is the kick down switch which is used to determine if the accelerator pedal has been depressed past full throttle. When activated the transmission downshifts into the lowest permissible gear based on current road speed to use the full power reserves of the engine. This is still present in most transmissions though is no longer as necessary to use as the TCU uses the throttle position sensor and rapid rate of change to determine whether a downshift may be necessary, thus there is no need to use the kickdown feature in most circumstances.
