Check your automatic transmission fluid.


Sounds like the transmission cooler is bad.


It is in the radiator.1991 Pontiac Firebird- a lot of oil in water of coolant holder(radiator), what could be the problem?
I agree with county boy. You either have a head gasket or intake gasket problem. If in worse, you have a crack in your block and the oil is going from the intake canal into your water canal. Thats why you have so much oil. But if any of your gaskets are gone, you will see the same. So country boy's answer would be best to start with and less expensive.





good luck,

Blown head gasket. You might also have coolant in your oil. If the oil is reddish it is transmission fluid.

Check your transmission cooler. If thats fine then you blew a head gasket or a intake gasket
