Allison 1000 6-Speed Rebuilt Transmission

The Allison 1000 6-speed transmission is one of the most durable and advanced automatic transmissions in the heavy-duty truck market. Introduced in 2006 as an upgrade from the original 5-speed Allison 1000, this 6-speed version was engineered to handle the increased torque and performance demands of modern diesel engines, particularly in Chevrolet and GMC Duramax-equipped trucks.

Known for its reliability and adaptability, the Allison 1000 6-speed features a robust design with advanced electronic controls, adaptive shifting, and grade braking capabilities. These enhancements make it a preferred choice for towing, hauling, and heavy-duty commercial use. Despite its strength, common issues such as torque converter failure and clutch pack wear can arise over time. Certified Transmission’s remanufactured units address these issues, ensuring like-new performance.
