Why does my car make a banging/clunk noise when I switch gears?

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. I would be first checking for motor and transmission mounts - are they worn or broken? It's possible this could cause the clunking you write of. Beyond that, if they are "good" then I would check for proper transmission operation. Hands on testing for this is needed too.
