Your Chevrolet’s transmission is the powerhouse behind smooth shifting and optimal performance—but only if it has the right amount of clean, high-quality transmission fluid. Whether you’re driving a 2025 Chevy Equinox through the streets of Ann Arbor, towing with a 2025 Silverado 1500 in Lansing, or cruising in a 2025 Trailblazer around Flint, regular transmission fluid checks are key to keeping your vehicle in top shape.
