Ok my JDM D15B tranny finally gave out. I had it replaced with a new one but now the tranny makes a weird shhhhhhhh'ing noise whenever Im on the gas,and only then. I was wondering what the possible problems might mean with a noise like that.

Thanks everyone!

Make sure everything is aligned properly in the tranny.
did you replace anything within the tranny (ie clutch, flywheel, pressure plate?)
have to make sure everything is precise or problems can occur
