TML Drivelines

TML Drivelines, a division of Tata Motors, is currently the market leader in axles and transmissions for medium and heavy commercial vehicles in India. It sought to introduce a new nine-speed planetary range gearbox with high and low ranges.


Shifting to low range whilst driving at higher speeds can have destructive and potentially life-threatening effects. A solution was needed to block the range shift when running above a set speed.

We were asked to provide components for a solution designed in-house by Tata. However, by applying our commercial vehicle expertise we were able to propose an integrated solution combining solenoid valve, actuator, fitting and silencer in a compact single unit.

Controlled by a new electronic control unit specifically designed by Tata to meet the application requirements, our solution offers a robust, life-of-vehicle product, as well as reducing assembly time, sourcing and logistics costs.
