It kinda pisses me off that oil change places don't check all the fluids. That is why I use those kind of places, they have a better ability to check those kind of things. As for the dealer not doing that is just nuts. Their company makes cars and pickups today so you basically have to use the dealer for an oil change and then they don't do the whole service job they promise.
