Yeah Hanso you're right, it's not the actual knob. Unfortunately that's just the only part I can fiddle with myself at the moment.
It seems more like the shift lever itself is transmitting whatever noise it is into the cabin.
Thinking that, other than something inside the transmission case, it might be the reverse lockout cable, or the shifter bushing, or perhaps some heat shield or something contacting the transmission. Really no clue though and the dealer wasn't helpful at all. Hoping you might have better luck having someone in the States troubleshoot yours.
At any rate it's annoying. If I can figure out how to get the centre console off I might have a peek but I'm no big time mechanic.
If the tranny goes...warranty.
