Better not to use Kick Down, as it usually triggers full throttle,,,, not always needed nor wanted..... I use the gear lever to select a lower Gear and then

the Throttle as necessary. If the Engine is in good Tune and the linkage in good order and set correctly then a part throttle downshift can be obtained.
This applies to all Auto Boxes. Holden Trimatics were horrible Cars to drive as the Factory settings held Top gear till the death. A simple change of a Valve Body Spring transformed the driving experience.
