Clutch whining
 

I put a ACT 6 puck unsprung clutch in my b16 hydro tranny about a year and a half and maybe 15,000 miles ago. About a month or so ago I started to notice a whine sound when I let the clutch out in 1st gear. It doesnt make this sound every time but there is a certain point in the middle of engagement that it makes an audibly loud shreak. Ive tried searching for this but cant find any convincing info on what this could be. Bad throwout bearing? Original TOB was replaced with the ACT one when the clutch was installed. Any other thoughts?

Ive never heard a clutch whine. You got tranny problems bro.

throwout or trans

I really dont think its a tranny problem. It definitely sounds like a bearing but Ive never heard another car do this before. Its only during engagement in 1st gear which is the wierd part. Has anyone had an issue like this before?

How's your transfluid?

Sounds like the syncros could be wearing as well, happens to scoobidoos. Is it louder when you engine brake?

Ask Complex about it.

scoobies are notorious for whining, mileage regardless. the newer sti's whine in all but 4-6, my wrx sounds like straight cut off-throtte, (in order of worst to least; 2-1-3) and has a slight whine in 1-2 but even stock low mileage ones do.

I think my trans fluid should be good. Wouldnt the whine continue through the whole 1st gear instead of just engagement if it were syncros? Maybe I should describe it as more of a shriek or squeel rather than a whine but its definitely loud. Theres certain degrees of it but it can be extremely loud if I let the clutch out just right.

i have also heard the noise in his car. its not in the tranny for sure. when i heard it i thought it kinda sounded like it was just the friction of the clutch disk causing the noise, but i have never heard a clutch disk make noise.

did we change the pilot bearing when we changed the clutch, i dont remember. it could be that.

my friends LS/VTEC w/ ACT disc used to do this, he said the clutch wasn't broke in properly.

Pilot bearing will howl all the time.

Clutch not broken in properly could make weird noise.
