im in the process of doing pretty much a complete overhaul of my 96. dual mass flywheel springs were shot so i got a new single mass flywheel kit, new pedal box, master cylinder, and new slave cylinder. I got everything put and and fired it up for the first time tonight. Everything seemed great except i noticed a sound of gears chattering when its sitting in neutral, but when i push the clutch in it sounds normal again. Im guessing something with the input shaft since it goes away with clutch pushed in, and yes i filled tranny with fluid. My question is, is it normal for chatter like that when you have a single mass?
