Awesome (kind of). Thanks!
The sound is similar, it's just odd because it feels like this is coming from directly under me. Also, I feel like I hear is even when I'm not shifting but it may be because i'm listening really closely now. It's driving me insane.Mine has it also and many others have experienced the same noise. Its' an issue with the passenger side shaft. Read the link below from the mazdaspeed forums. Sometimes it's annoying! My car is at the dealership right now and that is one issue they are working on.
Pop/thump/clunk noise (gear changes) Found!! - Mazdaspeed Forums
Did they ever figure it out for you?Guy take it to the dealer! let them brake their minds solving it!
I don't have a ride right now because I'm letting the dealer brake their minds solving it. Hopefully by tomorrow I get an answer.
