    Transmission oil can enter the coolant if the oil cooler in the radiator leaks, it turns the coolant milky in color.
    There is an oil cooler mounted in the block under the intake manifold, if that engine is shared with Saturn I think the coolers gave problems where they leaked. Perhaps look on a Cadillac specif forum.
    Google "Cadillac Catera oil cooler problems" I see quite a few postings about problems.
