    Just installed GM rebuilt 3yr 100,00.tranny.Fluid levels are correct BUT for about 10minutes at startup it makes a noise then goes away.Took Inspection cover off and bolts to flywheel are fine.Noise seems to be coming from torque converter.Hope i didn't get a bad rebuillt.Shifts fine and everything else is good.Like i said after 10 minutes sound goes away.Help? do i have to redo this again aaaah no PS sound is like a chirping sound,something rubbing in torgue converter or?

    hmmm...sounds like front pump is going bad? only reason i say this is because my Th350 on my nova made the same sound before it went kaput.
