I have a 2021 Chevy Colorado Lt v6 4wd. I bought the truck with 23000 miles. It now has 47,000. The truck runs great has been well maintained and has no issues shift. Should I drain and fill the transmission fluid and replace the filter or leave it alone? I know not to flush it. But I called a transmission shop to drain and fill it plus a new filter and he flat out told me if it’s working well not to ever change it. I want this car to run as long as possible. What would be the best way to maintain it?

Stay away from this so called shop. So strange that they would chase away business like this. They probably make more money replacing failed transmissions.
