Well I just got my auto to m6 conversion done put a brand new stock clutch in and the car makes the strangest noise in 1st and 2nd at low rpm its hard to describe but it sounds like a wooshing sound of some kind, the trans chatters a bit when clutch is out but I heard its normal, my main concern what the hell this sound is ?

 

I just got done too, and mine sounds like a couple marbles rolling around at idle clutch engaged. Works great, nothing unsual when under power, so I'm not worrying.

 

so i guess this is normal in these trannys, mines sounds like a big jar of marbles in low rpms with the clutch in

 

Well, if it making a bunch of noise with the clutch in, it could be a noisy throw out bearing, but I think that a certain amount of noise is not unusual with these things. Time will tell, or maybe others will tell, in which case we will crawl back under and make necessary repairs.

 

Mine does the same thing at very low RPM, it has run that way ever since I got it from the factory, I don't think it is any big deal b/c it runs great and has run great ever since the beginning
