How Much Should a Transmission Flush Cost?by Kendra Dahlstrom
In 2010, the average driver paid $100 for a transmission flush, according to TransmissionOilChange.com. Flushing the transmission every 30,000 miles extends its life and prevents drivers from paying thousands of dollars for a transmission replacement.
In 2010, Cost Helper estimates the cost of a transmission flush between $75 and $250. More expensive vehicles tend to fall closer to the higher end of the scale. Anyone living in an area with a high cost of living should expect to pay closer to $200 or $250.
The average driver will pay around $100 for a transmission flush. Vehicles purchased at a high price cost more to maintain, therefore cost more for a transmission flush.
