What type of transmission fluid for a 03 Chevy silverado with an mg-5 manual transmission?
The 2003 Chevy Silverado with an MG-5 manual transmission requires GL-4 gear oil. The specific weight will depend on your climate and the recommendations in your owner's manual. Look for a 75W-80, 75W-90, or 80W-90 GL-4 gear oil. Using a GL-5 gear oil is strongly discouraged as it can damage the synchronizers in your transmission.
