Thats not a level display, its transmission fluid life, and about the only time it ever goes down from 100% is if the car, or transmission has overheated.

Transmission fluid level is measured by a dipstick, exactly like the engine oil level.

Transmission fluid life is determined by comparing temperatures, time, loads, and speeds over a LONG period. Engine oil life is calculated from a similar algorithm.

Because transmission fluid is not subjected to combustion gas and acid pollution, it will last literally forever unless it is grossly overheated (in our cars the temperature warning comes on at 305 degrees - 305) or subjected to contamination from clutch band wear, metal particle contamination (final drive pinon wear) or torque converter failure. Modern transmission fluids, particularly DEXRON-VI, are some pretty tough products.
