The manual says to change it every 60,000 miles if driven primarily in heavy traffic with temps over 90, in hills or mountains, when frequently towing or delivery/taxi/police use. I changed the fluid in my 10 GT back at about 65,000 miles since I did not know the history of how it was driven the first 36,000 miles. I just drained the pan and refilled it with about 4 quarts of Toyota WS fluid. Drain & refill capacity is 3.7 quarts per the manual.Mick-F wrote:I guess at 60K I should do a transmission oil and filter change, or is the interval longer? I have had no problems just want to do the right PM
