new clutch. new noise

converted from dmf to smf and now i have very slight whine noise when accelerating. but on decel and downshifting i now have a very loud scary whine/growl/almost grindy sounding. iirc guys say youll have more noise after installing a smf but it sounds a little loud and scaring me

I believe there is a good possibility that the noise is the downpipe against the metal heat shield on the firewall. i may have tweaked it when i pulled the trans out. im gonna get under and look at if thats what it is ill just try to pry it back or loosen it and pry it. if that dont do it im stumped

pretty sure its not the downpipe. i pryed it back yesterday and it has decent clearance. still makes a very upsetting noise when slowing down/downshifting

it really sounds like bearing inside the trans is out or something. never heard the noise before the swap to smf. considering putting the dmf back in lol. the only thing wrong was the throw out bearing and a little play between the masses. otherwise the flywheel surface and pressure plate surface still have machine marks in them and the disc looks great

Make sure you've got PLENTY of ATF in that trans. Sitting all winter makes me think you've got a leak. Some people add more by romoving the shift leaver and topping it off there.

I changed the trans fluid last spring when i got it out with valvoline maxlife atf. pulled the fill plug when i put the clutch in and it was still full to the hole. how much extra are guys putting in there? whats the reason for this?

I've heard of a quart or more. They do it to stop gear rollover, or at least quiet the noise that come with a dual mass flywheel.
