Hello I'm new to my 2010 e550 from my beautiful 2006 911s. But I needed more room and wife was scared to drive Porsche . I'm hearing a single click or pop when putting pressure on tranny. For example if I take off hard I'll hear it most of the time on take off ( never after that ) or when reversing out of my driveway ( very steep going up ) I'll hear that same clink. Today when it happened out of driveway it even made same noise as I put the car in drive ( without moving). I don't know if it can be a bushing or tranny. If anyone can help, or if its typical for this car. Just nervous, had a perfect 911 and I only have car for a week and had to change emergency brake set up in rear ( was cracked and rattling over bumps).thanks for any help
