Using this cast aluminum PTO side plate cover is easy. First, make sure your vehicle is a 2001 - 2019 GMC/Chevrolet with a 6.6L Duramax engine. For 2001 - 2016 models, you'll use the kit with 2 covers, 12 bolts, and 2 cover gaskets. For 2017 - 2019 models, use the kit with 1 cover, 6 bolts, and 1 cover gasket. When installing, ensure the gasket is evenly torqued to avoid slipping. This will help the cover work properly and prevent oil seepage. As for maintenance, keep an eye on the cover for any signs of damage or wear. If you notice any issues, replace it as soon as possible to keep your transmission in good shape. Regularly check the bolts to make sure they are tightened, and the gasket is in good condition. This will help maintain the cover's performance and keep your transmission cool and running smoothly.
