The recommended frequency of a transmission flush varies between car manufacturers. However, because it does need to be performed from time to time, the owner’s manual will give you some idea of when your car will need a transmission flush. Some manufacturers recommend that your transmission fluid be flushed as often as every 30,000 miles, whereas others only recommend it every 100,000 miles.A transmission flush is part of the periodic preventative car maintenance of your vehicle, but there are also other factors that affect the recommended frequency. Your driving habits, the condition of the roads, and the climate can affect how long your transmission fluid remains effective. For example, the soaring temperatures in the Austin heat may cause your transmission fluid to break down more rapidly than in cooler climates.
