Planetary Gearset - Front
WARNING: This page is about a different car, the 2002 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
The planetary gear front carrier is driven by the input shaft.
- The front planetary gearset carrier drives the center shaft via the overdrive one-way clutch in 1st, 3rd and 4th gears.
- In 2nd, the front sun gear is held causing the pinion gears to rotate around the front sun gear.
- The pinion gears in turn drive the front ring gear and, with the front band applied, results in a 2nd gear ratio of 1.87 to 1.
- In 5th, the front sun gear is held causing the pinion gears to rotate around the front sun gear.
- The pinion gears in turn drive the front ring gear and, with the intermediate band applied, results in a 5th (overdrive) gear ratio of 0.75 to 1.
- The front planetary gearset is internally splined to the coast clutch for engine braking.
