The tranny is from a 99 SI, the car is boosted, has stock axles and stage 4 Clutch masters with Findaza flywheel . The problem is that the car shifts fine and all seems good except for this weird rattle coming from the what appears to be the tranny. It only does it when the car is in gear and it does not affect drivability or make any vibrations. This started about a month or so ago. The clutch that was on there before blew (the disc springs broke) and made the car difficult to put into gear. We replced the clutch with the stage 4 and after about a month or more this stuf started happening. We thought is could be the axle as the passenger side axle was about an 1 out but after we put it in it still does it. Rep[laced the axle also and still makes the sound.

The sound is like a marble in the tranny when it is in gear. When it is not in gear it is fine. this is from the inside of the car, not the outside. The tranny fluid is fine, changed it twice.

oh, the car is a boosted b20 with a t3/t4 and SI tranny, stage 4 clutch masters
thanks for the help

when you replaced the clutch did you replace the throwout bearing and pilot bearing?
