Ever since I got my 2016 F3-T SE6, it has made a loud "clunk" when first shifting into either reverse or first gear after a cold start-up. It is loud and I can feel it. All subsequent shifting is fine, except for 2 or 3 occasions when I had trouble shifting into first gear after a warm start-up.

Since I'm about to have my first (3000 mile) service, I was wondering whether this clunk is normal or whether it's something that I should mention?

Thoughts?
