A SIX-SPEED manual and four-speed automatic transmission are available across the 200SX range. The manual features a double-cone synchroniser system on second and third gears to provide fast and smooth gearchanges. The electronically controlled automatic, codenamed DUET-EA, communicates with the engine's management system to provide smooth and timely shift points. The standard six-speed manual transmission is a close-ratio unit with an overdrive sixth. There's also a dual-mass flywheel and a clutch with no hydraulic damper. Nissan claims this set-up minimises power loss. The automatic transmission interface controls engine torque for quick, smooth shifts. Turbocharger control gives high boost at low throttle openings and maximum boost at high speeds in fourth and fifth gears (manual) and third and overdrive (auto).
