Manual shifting is performed by moving a control on the console. Moving the selector forward provides for an upshift. A movement down allows for a downshift. This transmission is unique in that it will not automatically upshift if the driver brings the engine’s speed too high. All other transmissions of this design will upshift automatically at a predetermined engine speed to prevent damage to the engine. Honda vehicles use a rev limiter that prevents the engine from overspeeds. When some Acura models are operated in the manual shifting mode, they will start out in first gear and shift automatically to second gear. The transmission can only be shifted manually between second and fifth gears.
