LAS VEGAS, Nev. — Responding to requests for more product offerings that are easy to operate, Mack Trucks has a new family of driver- and fleet-friendly transmissions.

The new Maxitorque ES T300 roster of transmissions, which Mack says have been designed to maximize the performance of a Mack powertrain, feature triple countershaft design, high torque capacities, lightweight one-piece aluminum case/clutch housings, and revised ratios to meet the needs of today’s vocational and highway customers.

“As a longtime supplier of integrated powertrains, Mack is in a unique position to offer optimally matched engines and transmissions,” says Kevin Flaherty, senior vice-president of sales. “We took full advantage of that position when designing the Maxitorque ES transmission.”

Two new 10-speed transmissions have been added to the Maxitorque ES family. The new T310M and T310MLR offer low gear ratios in both forward and reverse to provide excellent maneuverability, the company says. Both feature Mack’s exclusive shiftable multi-speed reverse to maximize efficiency when operating in reverse gear. The Power Take-Off (PTO) mounting options, in both six- and eight-bolt designs, are plentiful presenting customers with several alternatives to handle a wide variety of tasks.

On all new Maxitorque ES transmissions the M designation stands for Multi-Speed Reverse, the L for Low Forward Ratio, and the R for Low Reverse Ratio.

Mack has expanded also its 9-speed line of transmissions from one to three models with the introduction of the T309 and the T309L, which has the low first gear ratio of 13.93 for customers looking to enhance maneuverability.

For heavy hauling and performance-oriented customers, new lower ratios on the Maxitorque ES 13- and 18-speed transmissions improve low speed maneuverability to better tackle a variety of vocational tasks.

The top gear .71 overdrive ratio makes these models an attractive choice for highway applications, as well.

A total of 20 different new Maxitorque ES transmissions are now available, covering 5, 6, 7, 8, 9 and 10-speed models with torque capacities of 1700 and 1800 lb. ft., as well as 13 and 18-speed models with torque capacities of 1800 and 2100 lb. ft.
