Hello audi world I'm new to this site and have a few questions about me and my girls audi a4 b7 2.0t. So we are having an issue with what I think is the trany but here's what happens. When driving and the rpms reach 3000 it has a jolt that goes through the body of the car but it doesn't necessarily do it on a shift just at 3000 rpms and not all the time what could this be. Any help would be greatly appreciated thanks.
