Transmission fluid cools, lubricates, and protects your transmission. Flushing intervals vary-some newer Chevrolets go 100,000 miles or more between flushes, while others may need service sooner. Check your owner's manual for your specific schedule. Over time, fluid breaks down and loses its protective qualities, so regular service extends transmission life and smooth shifting. Castle Chevrolet McHenry's Service Department can review your vehicle's maintenance schedule and perform transmission fluid service with genuine Chevrolet fluid. Call (779) 600-2956 to find out when your Chevy needs this service.
