Navistar has announced the Allison TC10 will be available with the Cummins X15 engine for its International LT Series of heavy-duty, long haul trucks and the Allison 3000 Highway Series will be available with the International A26 engine for its RH Series of Class 8 regional haul tractors.

“By offering Allison transmissions with International LT Series and RH Series, drivers will enjoy a premium environment with incredibly smooth shifting, in stop-and-go situations and over the road,” said Jim Nachtman, heavy-duty product marketing director for International.

Unlike automated manual transmissions, both the Allison TC10 and Allison 3000 transmissions use a torque converter to enable smoother and more efficient acceleration, according to the company. Both transmissions are engineered specifically for Class 8 tractor applications, designed to maximize powertrain efficiency while achieving and maintaining highway cruising speeds to save time and money.

“With the TC10 and 3000 Highway Series, Class 8 tractor fleets no longer have to compromise overall vehicle drivability, transmission reliability or performance,” said Heidi Schutte, Allison's vice president of marketing and sales for the Americas.
