The tittle kind of sums it up quite well lol So if i am running around and the tranny decides to keep the engine gear where it sits for 2-3 secs in 2.5k, i get this sudden metal clanking noise around the engine. Only around that 2k-3k rpms range. Its not very loud but its audible. I was going to inspect for loose catch pan or even loose catalictyc heat shield as sometimes it just something like that... but wanted to see if its common and you guys could tell me what it could be. It does not come up at any other scenario, when i floor the car, it runs just fine. Could say the noise happens sort of when the tranny is about to shift or so. Sort of like tranny hesitating? But the engine or tranny feel like they are jolting or having issues. Car runs smooth, just the noise. Its a 2009 TSX stock except for the 19" wheels just incase this might promote this issue.
