leaky main seal?
I was under my car changing o2's last night and saw a film of oil right between the front of the transmission meeting the bellhousing (?) . The oil drain plug was dry and around the oil filter the area was dry. Is this cause for major concern?
I'm figuring the rear main seal is bad and a little oil is making its way through. Maybe this is why my clutch is chattering a bit from a dead stop in 1st (zo6 clutch.) I have an extended warranty that should cover this. Am I on the right track with my thoughts? How urgent is this to get fixed? All input is appreciated!
