WARNING: This page is about a different car, the 2008 Mazda RX-8, 2007 Mazda RX-8, 2006 Mazda RX-8, 2005 Mazda RX-8, and 2004 Mazda RX-8. However, it is still accessible from the selected car via links, so may be relevant.
- The driving force from the input shaft is transmitted to the rear sun gear, which rotates clockwise causing the rear pinion gear to rotate counterclockwise. The rear internal gear does not rotate since it is locked by the low and reverse brake via the low clutch. As a result, the rear pinion gear rotates axially counterclockwise, overcoming the load of the stopped vehicle, causing the rear planetary carrier to revolve clockwise. Accordingly, the output shaft rotates clockwise and this driving force is transmitted via the propeller shaft to the driving wheels.
- During deceleration, the driving force is transmitted from the driving wheels. Due to this, the driving force becomes the reverse of that during acceleration and engine braking is actuated.
