Navistar is making the Allison TC10 transmission available as an option on International LT Series and the Allison 3000 Highway Series for RH Series spec’d with a Cummins X15 engine, according to an announcement.
Unlike manual or automated manual transmissions, Allison transmissions use a torque converter to enable smoother, faster and more efficient acceleration. Additionally, there is no dry mechanical clutch that is prone to wear. The fully automatic Allison TC10 and 3000 Highway Series transmissions are engineered specifically for Class 8 tractor applications. They maximize powertrain efficiency while achieving and maintaining highway cruising speeds.
Allison says fleets have documented 5 percent better fuel economy with TC10-equipped tractors over its manual or AMT-equipped tractors. Additionally, with Allison’s FuelSense technology, the TC10 and the 3000 Highway Series achieve the best fuel economy, regardless of driver experience or expertise. They shift at just the right points to maintain vehicle performance and maximize fuel economy, according to the company.
