when the engine or ignition is switched off and no key is in there... when you try to shift the stick it will not move it will be locked.... push that button in and shift the stick it will move ��
Its for towing or moving the car not by the engine, to save the torque converter.
Well my book says that it's not allowed to TOW the Auto gearbox, unless the front wheels off the ground.
So are you saying that the button disconnect the torque converter from the gearbox?
