I notice that whenever I start up the car and drive from 1st to 2nd, I hear a large 'clunk' from the bottom of my car. My friend says that its normal to hear some clutch noise when you are in lower gears but is this normal? When I have my window down, I can hear it loud and clear. This is usually when going from 1st to 2nd.
