Automatic Transmission Fluid Change Cost
We recommend changing the transmission fluid every 30,000–40,000 miles under normal conditions. If the transmission has a filter, that should be replaced as well. If you operate your vehicle under severe conditions (e.g. extreme weather, towing, or a lot of stop-and-go traffic), the transmission should be serviced every 20,000–30,000 miles.
Your repair shop may recommend a transmission fluid flush, which will require up to 16 quarts of transmission fluid. This will increase the parts and labor price when compared to a normal drain and fill of the transmission.
