Automatic Transmission Fluid and brake fluid replacement

Hi all,

All of the mileage on my car is highway driving. I average about 450 miles per week. The Nissan dealership where I get my oil changes has been recommending an automatic transmission fluid replacement as well as a brake fluid flush since around 20,000 miles.

Now that I’m at 82,000 miles, I’m considering getting this service done. Could you provide a ballpark estimate of what this typically costs? For reference, my car has a 3-cylinder engine with a CVT transmission.

If this service isn’t necessary yet, at what mileage would you recommend having it done?

Thank you.
