Is it good to change transmission fluid on high mileage?

Changing the transmission fluid on a high-mileage car is risky. Don’t do it unless your transmission is running fine and the fluid is first-rate, because it can make transmission failure imminent.

Is it better to flush or drain transmission fluid?

“The biggest benefit is the newer, cleaner fluid helps keep the transmission running at the temperature it needs to be, and newer fluid has better lubrication properties,” Gunning said. According to the experts we spoke with, expect to pay $200 to $250, on average, for a flush.
