Allison Transmission launch the TerraTran

TerraTran from Allison Transmission

Innovative new propulsion solution for off-highway market offers enhanced drivability and manoeuvrability

ALLISON Transmission have announced the launch of the TerraTran, their latest innovation in propulsion solutions purpose built for the global construction, mining and quarrying markets.

A variant of Allison’s proven 4000 Series transmission, the TerraTran is purpose built for off-highway applications such as articulated dumptrucks, with enough application flexibility to allow Allison to target multiple additional on-highway opportunities.


TerraTran was developed based on customer feedback, which indicated a need for the proven reliability and durability of Allison’s 4000 Series transmission, but with increased horsepower, torque and GVW capability, while also adding fast reverse capability.

TerraTran, which has maximum power capability of up to 800hp, and torque capability up to 3,025 lbs/ft, dependent upon the application, features seven forward and two reverse speeds. With the additional fast reverse, TerraTran delivers improved productivity and optimized efficiency.

According to Allison, field tests conducted over approximately two years have demonstrated that TerraTran delivers enhanced drivability, gradeability and manoeuvrability under demanding operating conditions.

Kartik Ramanan, executive director of global off-highway sales, customer support and service engineering at Allison Transmission, said: ‘TerraTran leverages Allison’s more than 65 years of experience moving earth, minerals and precious metals around the world where Allison Automatics have proven themselves in some of the most challenging conditions imaginable.’
