| | Oil or trans fluid in my coolant
I have a 98 firebird v6 3.6 and need some advice. There is either trans fluid or oil in my coolant I need to know how I can tell which one it is. Checked oil it is at its normal level and it looks fine not watered down no milky color or bubbles. I checked the trans fluid and it also is at its normal level and is very dark but not milky. Car does not seem to be smoking and engine runs fairly well does not seem rough like I would think it would with a bad head gasket. I am loosing coolant but cant tell where. Obviously I am hoping that it is trans fluid meaning a bad trans cooler I think (much better than if its a bad head gasket) Please help! How can I figure out what is actually wrong?
