If you have a car with a vacuum modulator on an automatic transmission (I don't know your model specifically) and if it is a gas-burner rather than a diesel, and thus gets its vacuum signal from the engine manifold, and if the diaphragm in the vacuum modulator ruptures, it is possible for ATF to be drawn up into the engine manifold, then into the cylinders. At this point, it should be burned up or expelled into the exhaust (where it will ruin the catalytic convertor), but in some cars in some cases it has been known to flood the rings badly enough that it ran down the cylider walls into the oil sump. Of course, on SAABs and some other FWD cars on which the engine sump and transmission share a common casting, some other possibilities are more likely.
