Noticed my clutch (g56 unit) is squeeling a bit lately. Seems to be worst when letting of the throttle on decel. Goes away when i push in clutch, doesn't do it at a stop/idle. Throwout bearing? or input bearings?

Had the tranny fluid changed not to long ago, wonder if they didn't overfill it or put wrong fluid in....any ideas

Thanks, RB

 

Crankshaft bushing/bearing to imput shaft makes a squeal when speeds are slightly different.

 

Checked tranny fluid and it is right at the bottom of fill port. i always put an extra 1/2 qt or so but level looks ok. noticed on my receipt that the shop put in a castrol mulit-vehicle atf, not the the redline C+ we agreed on that is atf+4 approved. Could this have something to do with squeeling sound?

what would make crankshaft bushing/bearing to input shaft go bad?
only 69k miles on clock, stock motor.

 

Throwout bearing?
