Sturdy and Durable Design

Sturdy and Durable Design

Allison transmissions are built to last. They are sturdy in their designs and quite durable in their construction. Allison Transmissions are built using high-quality materials and meticulous manufacturing processes. This helps build transmission systems that can endure heavy-duty applications and function effectively even in the most demanding conditions, like in construction projects, mining sites, and transportation.

Fully Automatic Operation

Fully Automatic Operation

Allison transmissions are very effective in their fully automatic operations. This means there is no being hassled by a clutch pedal or manual shifting to control the system. Instead, all controls are managed by advanced electronic and hydraulic systems. From seamless gear changes to powering up the wheels, these automatic controls and efficient systems help simplify driving and reduce driver fatigue while also enhancing vehicle productivity.

Diagnostic and Telematics Capability

Diagnostic and Telematics Capability

Allison Transmissions allows for complete monitoring and troubleshooting with its advanced diagnostic and telematics capabilities. The integrated onboard diagnostics allow the monitoring of transmission health and performance parameters. This enables early diagnosis of potential problems, thereby helping to reduce downtime. The telematics helps fleet managers control vehicle operation and maintenance costs by enabling remote monitoring and data analysis.

Adaptive Shift Technology

Adaptive Shift Technology

Allison Transmissions are also equipped with state-of-the-art adaptive shift technology that helps monitor the speed, load, and driver input and optimises gear selection and shift points in real-time.
