I have a gsr motor and there is a strange noise comming from my tranny. It happend after I swapped out the clutch but then it went away. Now its comming back. It happens at 2500 rpm. Doesnt matter if im sitting still, in gear, not in gear, moving, not moving, or anything else. If the motor is at 2500 rpm then it makes a rattle noise. I checked for heat shields and anything else it could be and I deffinetly know that its inside the tranny. Anyone know what it could be? I didn't resurface the flywheel because it looked good anyway. Could that be the problem? The car drives perfectly though, so im not extremely worried about it, but the noise is kinda loud. The noise goes away at about 3200 rpm too. Anyone know what it could be?? TIA
