2020-2021 Silverado & Sierra 1500 3.0L Duramax Transmission Pans

The stock transmission pan on your 2020-2021 Silverado or Sierra 1500 3.0L Duramax does the job of holding your truck's transmission fluid in one place, but its flimsy plastic construction and lack of a drain plug make it a one-time-use item in most cases while also making fluid and filter changes a huge pain. Tier One's selection of 2020-2021 Silverado & Sierra 1500 3.0L Duramax transmission pans make basic maintenance easier and help keep your 3.0L Duramax 1500's transmission running cooler all in one place. Each of these Silverado & Sierra 3.0L Duramax transmission pans are made out of cast aluminum, allowing them to be reused for the life of your truck. These pans come standard with drain plugs, and many also feature cooling fins and increased fluid capacities that help reduce transmission temperatures, even when you're pushing your diesel Silverado or Sierra hard.
