The BD Diesel 1061650 Deep Sump Transmission Pan is built specifically for trucks running the Allison 1000 transmission between 2001 and 2019, and it’s designed to handle heat like a pro. With a deep sump design that increases fluid capacity, this pan gives your transmission more oil to work with, which naturally helps lower operating temperatures. That extra capacity, combined with the heat-dissipating aluminum fins, helps prevent the kind of thermal breakdown that can lead to slipping or long-term wear. It’s a straightforward solution to a problem many heavy-duty truck owners face, especially when the work gets demanding. Built Tough with Real-World Features That Matter This isn’t just a bigger pan—it’s engineered for durability and ease of service. The cast aluminum body adds structural rigidity to your transmission case, which helps reduce flex under load and improves overall longevity. It also includes a magnetic drain plug to catch metal shavings, plus a dedicated port for a transmission temperature sensor, making it easier to monitor fluid temps if you're running a gauge. The kit comes complete with a deep filter, O-ring, and all the hardware you need to install it right the first time. Whether you're towing across the country or running weekend upgrades, this pan gives you peace of mind by keeping your transmission cooler, cleaner, and better protected.
