Allison 1000 Torque Converters

The combination of a Duramax diesel and Allison transmission may be pretty potent, but the stock torque converter is a potential weak point that can let you and your tough Silverado or Sierra Duramax build down when you tow extremely heavy or add on a bunch of power and torque. Tier One's selection of performance Allison torque converters are all designed from the ground up to handle hard applications and big-time horsepower and torque without the risk of cracking, warping, burn-up, or failing completely. We carry a variety of torque converters for Allison 1000 transmissions that range from uprated stock replacements all the way to billet Allison torque converters or Allison triple-disc torque converters that can handle immense levels of power and give you solid lockup, even at elevated power levels.
