If you check your oil, look for foam in the oil. Also foam on the inside of the oil cap. That would be coolant in the oil. Look for pooling around the LIM. When you start the engine for the first time of the day, check the exhaust, does it smell a little sweet? All signs your LIM/UIM is leaking.
Is DEX bad stuff? That will depend on who you ask. I say no, it'* not. As long as it'* maintained, just like any other fluid. If it gets low and air gets in to the fluid and or it gets old it can brake down the gaskets. If your going to do a gasket change, just flush the system and fill with green stuff.
If you have over 80k on the car, changing the gaskets is a good idea. There is a write up in the tech info section about doing it. It'* not a overly hard job. But it will take 4 to 7 hours. And you will need a torque wrench. Having help makes it easier.
If you have coolant disappearing in to the void, it'* a good bet it'* because of the gasket.
