X-TRAIL is available with a five-speed manual transmission and an optional electronically controlled four-speed automatic. The manual transmission is designed for high-power engines and features double cone synchronisers for optimum shift feel. Nissan also claims it is one of the most compact and lightweight gearboxes in its class. The automatic features Nissan's "E-flow" torque converter designed to increase the efficiency of the transmission and improve driving performance. X-Trail uses a version of Nissan's All Model 4WD system, which drives the front wheels in normal conditions and, when in auto mode, automatically sends torque to the rear wheels via an electronically controlled coupling when required. A "lock" model fixes front to rear torque distribution in a 57:43 ratio at speeds below 30km/h.
