2019-2021 Silverado & Sierra 1500 5.3L Transmission Pans

The stock transmission pan on your 2019-2021 Silverado or Sierra 1500 5.3L doesn't do your tough truck or its 8L90 any favors, other than holding your transmission fluid in one place. It's stamped steel construction is pretty flimsy, and it doesn't have the best heat management in the world. The good news is that we here at Tier One have more than a few 2019-2021 Silverado & Sierra 1500 5.3L transmission pans available that will help your truck's 8L90 transmission see improved reliability and a longer lifespan. Each of these pans is made out of cast aluminum which is more rigid than stock and offers up improved heat dissipation. These 8L90 and 6L80 transmission pans come standard with drain plugs to keep maintenance easy, and many of them also have cooling fins and larger fluid capacities to further improve cooling and lubrication.
