Maybe I know where the leak is coming from. While the car was on a lift, having the front end looked at, I noticed the auto trans had oil all over it. (Not fluid!) "Appears" the rear main seal may be leaking/seeping. Could not ascertain that it was in fact the rear main but is highly suspect. No oil has been leaking on my driveway so it's not that bad "yet!" If it's bad the auto trans will have to be removed for access to the seal. Not something I can or even want to do in my driveway. The oil is probably blowing back on the exhaust when driving and is what I'm smelling when I come to a stop. "Guess could put a diaper on it and change it once a month." LoL
