Planetary Gearset - Overdrive (O/D)

Geartrain

Power is transmitted from the torque converter to the planetary gearsets through the input shaft. Bands and clutches are used to hold and drive certain combinations of gearsets. This results in 5 forward ratios and 1 reverse ratio, which are transmitted to the output shaft and differential.






Planetary Gearset - Overdrive (O/D)

For component location, refer to Transmission Transmission Assembly.

The planetary gear Overdrive (O/D) carrier is driven by the input shaft.

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