well I there is a way to check the fluid level on all transmissions but they dont let the customer know new cars. Like the cavalier theres a plug on the top of the transmission. what they do is fill up the car removing all the fluid and then re adding the spec amount to it. What i would do is completely clean the area where the fluid is located at. I mean completely spotless go back in about a month and compare what it looks like. if you have about the same spot coverage on your car/seal then you know thats what your loosing per month. Just remember that $100 is expensive to the point of how much you will need to keep checking the car.
