Planetary Gearset - Overdrive

WARNING: This page is about a different car, the 2009 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.

For component location, refer to Transmission .

The planetary gear overdrive carrier is driven by the input shaft.

The overdrive planetary gearset carrier drives the center shaft via the overdrive one-way clutch in 1st, 3rd, 4th and REVERSE gears.
In 2nd and 5th gears, the overdrive sun gear is held causing the pinion gears to rotate around the overdrive sun gear.
The pinion gears, in turn, drive the overdrive ring gear resulting in the 5th (overdrive) gear ratio.
The overdrive planetary gearset is internally splined to the coast clutch for engine braking.
