There is not a way to measure the fluid, unless you drain the pan. If you are low after you have drained it, you will know how much. You should drain the fluid & replace every 50k miles, to keep things shifting properly. When the fluid gets old, it turns acidic & starts eating the rubber seals. The Mechatroinic Adapter seal is usually the one that gets hard, then the fluid starts to bypass the valve body causing erratic shifting.
