My '01 S10 has 108000 miles on it. About 4000 miles ago I noticed oil specs on the tailgate and traced it to fluid from the tranny (auto) vent tube. Had the trans. flushed and filter serviced but still have an occasional fluid burp, doesn't seem to be a constant problem, but has happened 2-3 times since the serviceing. The dealer knows about it but doesn't seem to have a clue where to look. Anyone have an idea what to do? There aren't any trouble codes coming up.
Thanks
