2007.5-2010 Silverado & Sierra 2500 & 3500 Duramax LMM Transmission Pans

Your Duramax LMM's factory transmission pan isn't much to write home about, and even though it does a fine job of holding in transmission fluid, that's about all it manages to do. Tier One's selection of aftermarket deep transmission pans for 2007.5-2010 Silverado & Sierra 2500 & 3500 Duramax LMM trucks don't just hold in your fluid, they can also improve both lubrication and heat dissipation so that your transmission lasts the life of your truck. Each of these Duramax LMM transmission pans feature deep sump designs and are made out of cast aluminum which gives you the double whammy of increased fluid capacity and better heat mitigation than the stock stamped steel pan. These Silverado & Sierra HD transmission pans feature built-in drain ports to keep fluid changes easy, and many also come standard with NPT ports that allow you to run analog temperature sensors for aftermarket gauges.
