On an AT, the car will throw up a warning and the tranny will stop shifting to protect itself if the fluid gets low. One of my tranny fluid lines running to the cooler failed and threw tranny fluid all over my engine bay. Lost all the pressure and probably 85% of the fluid in less than 5 secs. Suppose to get it back today after being in the shop for a week (cause of the holiday). I would high suggest that anyone with an AT do a quick visual inspection of the AT oil cooler lines whenever you do an oil change! They're easy to check (bottom, drivers side behind the fan shroud) and it could save you the hassle of getting stuck somewhere.
