There are two different kick down shift strategies, part throttle, no kick down solenoid activation, full throttle kick down, with the kick down solenoid activated. In Both strategies the pressure control valve, Bowden cable moves. AJUST the Bowden cable make it tighter, no slack in it.
An easy and quick method for checking the KD solenoid electronics; open the passengers side door, floor the gas pedal, you should hear a click in the back of the car, if you do; the kick down electric and Mechanical system are working.
If you don’t, the kick down switch under the gas pedal is bad or you need to adjust the activation lever behind the pedal, or no voltage to the solenoid. The KD solenoid can still be mechanically bad, it’s only a plunger.
