Trans Oil Pan

This Mishimoto Aluminum Transmission Pan is a direct-fit, high-performance upgrade for your 2001-2019 Chevy/GMC 6.6L Duramax. Cast from high-quality aluminum and powder coated Gunmetal Gray, our transmission pan is a robust and long-lasting upgrade for your vehicle's transmission. With a sleek design and bottom ribs, this pan not only adds to the overall aesthetic of your truck but also provides improved cooling performance.----This transmission pan features internal baffles that reduce sloshing and enhance heat dissipation, resulting in smoother transmission performance. All the headaches that come with a flat gasket and messy sealants are eliminated with our precision-machined dovetail-style groove and O-ring seal. This groove positively retains the O-ring, so you never have to worry about it falling out of place during installation. Additionally, the Mishimoto 2001-2019 Chevy/GMC 6.6L Duramax Aluminum Transmission Pan adds an extra 6.1 quarts of ATF to help maintain optimal transmission operation.----Fed up with the frustration of trying to hold up a transmission pan with one hand while threading the fasteners in with the other? Mishimoto has you covered with pre-installed bolt retainers that hold the fasteners in the pan, allowing you to easily thread the bolts without dropping them on the ground, your head, or worse, that pan of nasty transmission fluid you just drained. Additionally, our pan comes equipped with a magnetic drain plug for easy draining and a 1/8-inch NPT port and plug for temperature sensors to make servicing your transmission and monitoring temperatures a breeze.----This direct-fit upgrade offers affordable durability and helps maintain smooth transmission operation, ensuring a long life for your transmission. Like all Mishimoto products, this transmission pan is backed by the Mishimoto Lifetime Warranty.
