I don't know if this is normal but when my car shifts gears, it makes like a slight blowoff vavle sound. (it makes a slight ppsshh sound). I have an automatic and it is all stock. Is this normal or is there some problem? thx.

Mine does this too. Nothing to be worried about. I think that the noise is the sound of fluid being redirected throu the valve bodies in the transmission.

Check under the hood, and see if a ricer snuck one of the electronic blow-off valves in there. If so, immidiately douse your car with gasoline, and toss a match at it. It's been molested... :?

Mine does the same thing, i brought it to the honda dealership and they said it was a normal noise that it was just the air intake. I personally think it sounds pretty tight
