Initial Gear In 1st gear, the scaled-down Sunlight gear is driven clockwise via the turbine during the torque converter. The planet copyright attempts to spin counterclockwise, but is held continue to from the one particular-way clutch (which only lets rotation during the clockwise course) as well as the ring equipment turns the output. The modest gear has thirty enamel along with the ring equipment has 72, Therefore the gear ratio is:
