Maxitorque Transmissions

There are several reasons to insist on a Mack truck with a Mack transmission. Mack is the only truck manufacturer offering the benefits of integration and single-source accountability for the engine, transmission and chassis. Mack offers the only transmission with a triple, countershaft design that disperses load between three shafts versus two. Mack's exclusive, shiftable multi-speed reverse allows for precision off-highway driving. And our transmissions provide more PTO mounting options than any other transmission.

Purposeful power
With ratings up to 2,100 lb.ft., the Mack family of transmissions delivers the right torque for instantaneous pulling power. The Maxitorque T300 Series confirms Mack as the undisputed vocational leader where demanding tasks require specific needs. With 19 different models and 6 to 18 speeds, there's a Maxitorque ES transmission perfect for your application. Three 10-speed models head this outstanding lineup: two for the vocational market with multi-speed reverse, and one highway/vocational T310 model. In addition, the popular 9-, 13- and 18-speed models are at home on the jobsite or on the highway. Designed exclusively for use with the Mack Maxidyne engines, the TM300 models are an excellent choice for mixer and dumper applications.

Proven performance
There is a Maxitorque ES transmission to match the torque capacity for all Mack engines. Like its predecessor, the Maxitorque ES T300 features our proven, compact, triple-countershaft design. The T300 Series includes a one-piece aluminum case that's lightweight and stays cool.

Smooth shifting
The shift rail profile and light touch design of our transmissions allow for smooth shifting in and out of neutral. Sliding clutches permit quicker, smoother shifts while increasing durability. A tighter ergonomic shift pattern is easy on drives for improved comfort.

Unmatched maneuverability
Lo and lo-lo ratios for exceptional maneuvering and slow speed control, as well as our exclusive, shiftable multi-speed reverse for precision off-highway driving, are available. For highway cruising, overdrive is standard.
