300,000 - 550,000 miles is the typical life of the 70's, 80's and early 90's Toyota automatic transmissions if the owner was over 30 and drained and refilled the 2-3 quarts in the oil pan (and 1+ quart in the differential of some FWD models) every 15,000 - 30,000 miles and was careful to maintain the correct fluid level at all times.
Under 30 owners tend to have a leadfoot when driving in the city and suburbs and no amount of fluid draining and refilling or flushing or use of auxillary filters and coolers will prevent heavy wear of the clutch and brake discs inside their transmissions caused by full throttle starts from stop signs and stoplights.
