hi all,

I have a 2012 mustang v6 with stick shift (current mileage ~3.5k miles).

Lots of times, when I upshift from 1st to 2nd gear (and rarely when I go from 2nd to 3rd), I hear a strange rattling noise (1-2 seconds) that seems like coming from the rear center/right of the vehicle. It doesn't sound like grinding but more like 2-4 knocks from a deep chamber. I have my windows mostly rolled up and so, don't really know how it sounds from the outside.

Though I have noticed this from the beginning I was a bit lazy in getting it checked as I thought it will become better with age (like wine :) ). Big mistake I guess.., it hasn't ... and so, here I am checking to see if anybody has seen something similar or knows why it might be happening.

I am trying to see if I can figure out when exactly it happens...as in does it happen when I step on clutch...or between the time when i step on the clutch and shift gears...or whether at the time when I actually shift gears. Will post if I get more clarity on this.11
