HSWL 284C

The HSWL 284C is a field-proven transmission with state-of-the-art technology that will also meet the requirements of the coming decades. It ensures maximum mobility, performance and acceleration of the vehicle in any terrain. The electronically controlled automatic transmission takes the strain off the driver, especially in difficult operating conditions. In conjunction with the modern braking system, optimum driving characteristics are achieved. Thanks to its exceptional reliability and service life, the transmission makes its contribution to the survivability of the vehicle and, above all, the crew.
