I have a 2000 Grand Prix Se and I just notice a oil like substance in my coolant recovery bottle under the hood. The car runs perfectly and idles very smooth. Just after changing my oil two months ago I had to add one quart of oil, after the check oil light came on. My car has 69K miles
Questions:
Thanks in advance
If you got an Oil like residue in the bottle check the radiator to see if the you got oil in there. May be a leak in the radiator side tanks where the trans cooler is, allowing trans oil to mix with the coolant.
Good Luck.

isnt that a totally seperate assembly?
Some tranny coolers are in the radiator core, so no.
If you are thinking head gasket, you would usually have the opposite effect of water in the oil and usually carbon in the coolant. And definitely, coolant loose.
