2010 MC Powershift transmission "clunk"

[Midnight Man]

Howdy all, and thank you for reading!

As a recent addition to the Mondeo owners, I have a fairly simple question. When I start my LX TDCi (Powershift) from cold, I hear a "ca-lunk" - not loud, but you can hear it - it sounds almost like the transmission is engaging as it were, if that makes any sense?

In all respects, the car drives perfectly well, doesn't miss a beat on highway or in city traffic.

What I'm wondering is - is that "engaging" type noise as I describe above normal, or something worth investigating?
