2006 Chevy Aveo manual tranny. Major leak from a pan behind the oil pan on drivers side. Is not oil but gear oil. Pan has several bolts on it, does anyone know what the pan is?

The manual transmission does have an oil pan. Try tightening the pan bolts to see if any have come loose causing the leak

Oil leak passenger side 300 turbo sedan, some on front passenger side wheel. Never lost oil pressure, but dipstick showed very little oil in crankcase on immediate after-run check. Have not started...

Add about 2.5-quarts of new engine oil to the engine.
Remove the passenger-side wheel, and support the car on jack-stands.
Start the engine and look for oil leak.
Chances are leaks are coming from failed oil-pan gasket or the drain-plug.
The head-cover gasket could be failing as well..
