The Mack mDRIVE® 13ADA is a 13-speed automated manual transmission (AMT) designed for heavy-duty highway and vocational fleets that demand precise control and maximum durability. The “ADA” designation identifies it as a direct drive unit with an additional low/creeper gear, delivering enhanced startability and performance under heavy loads while maintaining fuel efficiency at road speed.
Seamlessly integrated with Mack MP® engines, the mDRIVE 13ADA uses advanced electronics and clutch automation to optimize every shift. Its rugged internal gearing and direct-drive configuration reduce parasitic loss, ensuring reliable power delivery to the driveline. Built with a lightweight aluminum housing, it provides strength without unnecessary weight, extending component life and improving payload capacity.
