THE all-new four-speed automatic transmission is designed in-house, weighs 7kg less than before, is 33mm shorter and is driver-adaptive. It includes both uphill and downhill slope control. The five-speed manual transmission is also improved. The "hill holder", which operates the brakes whenever the vehicle is stopped on a hill to prevent it from rolling backwards, remains a standard feature. The Liberty's automatic transmission four-wheel drive system is known as an "active torque split system" and uses a computer to constantly monitor the driving conditions and distribute torque via a transfer clutch accordingly.
The system can infinitely vary the distribution between 95 per cent front and 5 per cent rear-wheel and is predominantly front-wheel drive during normal road running. In the manual transmission, a viscous coupling limited slip centre differential is used to constantly transmit the engine power to all four wheels.
Did you know?The new auto offers normal or power modes. It allows the driver to select "manual" mode and select gears via a gated shift. "Hold" mode provides greater driver control in more severe conditions
