Weird noise when shifting

[Draghkar]

Well, I'm thinking that the noise I'm hearing is the same as most people. It only did it a bit today, but as brennan said, it happens when I put in the clutch when accelerating moderately, or quickly (although I haven't really been accelerating too quickly just yet - gotta break it in a bit). Slow accelaration doesn't seem to do it. Even though I initially said I wouldn't call it a squeak, I can see where "squirrel laughing" comes from.

Oh well, at least it seems normal. Now I can just turn up the stereo and not notice it

i was wondering if the noise you hear is the same as the one i also hear which is a faint "shhhhhhh" sound that seems to be coming from the engine area. i had taken the car to mazda and they heard the sound and said that they will have to wait for it to get worse or at least be constant to check it out further. i was however able to now duplicate the noise by pulling on the throttle while under the hood and i seem to hear the sound coming from the manifold . i will have to bring it back so i can duplicate it for the tech guy.

could be the bpv, motor mounts, swaybar bushings, etc., etc.

I just heard the same sound tonight. Its not the wastegate, not the BOV. I was shifting from 3rd to 4th under ~3psi(i have a boost gauge and i was getting on it a little). When it happened the car lurched forward slightly(decelerated). My parents were in the back of the car and felt it as well. I hope to god its not the LSD or Tranny in any way.

Is it when you shift faster than normal? My car has a very very slight grind when I shift Fast at high RPMs from first to second. I was told that putting Redline MT-90 tranny fluid in should eleminate that. It is pretty much a synchro noise I think. It isnt bad at all but it is noticeable. I had a this sound in my Honda but like 100 times worse.
