this is a strange one... Gear changes are sweet as a nut... its just when the car is not running and you fiddle the gears, you can hear them engaging....now its sorta sounds unhealthy but is there anything to worry about? obviously the box has to make some sort of sound when engaging but is it normal.....??
every car I've ever sat in and twiddled the gearstick in has done that! probably because nothings turning round while the engines not running.
