The cable will only drop one gear on the auto tranny! The kickdown switch activates the kickdown solenoid which forces the tranny to drop to the lowest possible gear! Example: On my 190E my tranny will shift at 4000 RPM from 1st to 2nd when floored but the kickdown not activated! If I floor it to the kickdown I get a shift at redline! At 65+MPH my tranny will not downshift to 3rd unless I hit the switch, make pasisng a little better when you can actually accelerate! The cable portion of the tranny kickdown only drops a single gear, so if you are going 20MPH and hit the gas you will only drop to 3rd instead of 2nd! Well at 20 3rd is kind of a waste! On my W203 the kickdow is a hair diferent since that has an electronic throttle and is also a 6 speed! It acts to not only downshfit the auto tranny, but also to tell the ECU that you are at WOT!
