Introducing the DmaxStore High Capacity Transmission Pan, the perfect upgrade for your Allison 1000. Engineered to enhance cooling, improve performance, and ensure transmission longevity. Cast out of durable aluminum, this transmission pan is built to withstand the toughest conditions while providing superior cooling capabilities. The cast aluminum construction dissipates heat more efficiently than the OEM material, effectively reducing operating temperatures and extending the life of your transmission. With its premium textured black powdercoat finish, the DmaxStore High Capacity Transmission Pan not only looks sleek and stylish, but it also offers added protection against corrosion and wear. One of the standout features is increased fluid capacity, an additional 1.35 gallons vs OEM which allows for better heat dissipation to help prevent overheating. The internal rib design serves multiple purposes from reducing fluid sloshing, preventing aeration and ensuring consistent lubrication throughout your transmission. Additionally, the Internal and External ribs maximize the surface area for improved cooling efficiency and strength. An oversized magnetic drain plug facilitates quick and hassle-free services while efficiently capturing metal particles, preventing them from circulating through the transmission system and potentially causing damage.
