Got a 2020 Buick Enclave with 106,000 miles. Is this in need of a fluid replacement?

2020 Buick Enclave

The 2020 Buick Enclave uses DEXRON-VI automatic transmission fluid. A standard drain and fill requires about 5.5 quarts, while a full capacity (9T65 9-speed transmission) is approximately 10 quarts. Fluid changes are generally recommended every 90,000 miles (or every 30,000–45,000 miles under severe driving conditions)
