Default clutch/flywheel noise?

okay so i have searched to see if any one else has this problem and all i can find is flywheel chatter at a complete stop. i had a competion clutch and flywheel installed today (stage 2) and it drives fine and engages and disengages like it should but when i start off slow in first or 2nd and even in reverse i hear noises coming from the trany. is this normal because i have a lighter flywheel??? all help will be appreciated.

Don't see how a flywheel-clutch combination would effect the transmission. Sorry.

i dont mean the trany itself making noise. but when i engage at a low rpm it makes noises from the clutch area.

This is absolutely normal. The noise associated with lightweight flywheels, and often mistaken for clutch chatter actually comes from the transmission. The stock dual-mass flywheel is designed to absorb these noises. When you switch to a lightweight flywheel you lose that muffling effect and the rattling sound produced by the transmission becomes audible.

After market flywheel-clutch makes all sorts of strange noises. It might sound like a cement mixer. You get used to it.

Depends, do you have actual clutch chatter or just a rattling sound? ...there is a difference.

This is clutch chatter:

That can be caused by a lot of things such as an uneven surface on the clutch or flywheel and isn't exclusive to just aftermarket clutch/flywheel combos. If it's just the rattling sound I'd lean more towards there being an aftermarket unit installed.

There is a little cover on the bottom where your engine and tranny meet, if you remove that (just one bolt holds it on) you may be able to get enough of a peak inside to determine if you have an aftermarket flywheel.
