2011-2016 Silverado & Sierra 2500 & 3500 Duramax LML Transmission Pans

The factory transmission pan on your Duramax LML Silverado or Sierra does the job of holding in your transmission fluid, but that's basically all it does, which may not be enough on high-powered Duramax LML builds. Tier One's transmission pans for 2011-2016 Silverado or Sierra 2500 & 3500 Duramax LML trucks not only keep your transmission fluid in the correct place, they also help improve lubrication and cooling. These transmission pans feature deep sump designs with cast aluminum construction that give your Duramax LML build the one-two punch of increased fluid capacity to improve lubrication and improved heat dissipation to lower your overall transmission temperatures. These transmission pans all come standard with built-in drain plugs, and many also include NPT fittings that allow you to add analog temperature sensors to keep better tabs on your truck.
