The Mack Trucks Mack mDrive HD Automated Manual Transmission for Mack TerraPro concrete pumper models is available in 13- and 14-speed options to offer improved performance, durability and uptime in an easy-to-operate package, the company says. The AMT comes with standard split-shaft PTO functionality, receiving output directly from the transmission to supply higher torque for large auxiliary equipment. The mDRIVE HD for concrete pumpers is paired exclusively with the 11L Mack MP 7 engine, and will be available with higher horsepower and torque ratings than equivalent models with conventional automatic transmissions. It will be monitored by the company's GuardDog Connect telematics solution, which provide proactive monitoring and repair planning, real-time diagnosis of issues, repair scheduling and confirmation that needed parts are in stock and ready to install.
