Geartrain

Power is transmitted from the torque converter to the Ravigneaux-type geartrain components through the input shaft and forward clutch cylinder and shaft.
- The geartrain contains a compound planetary set connected by dual pinion gears.
- By holding or driving certain members of the gearset, four forward ratios and one reverse ratio are obtained and transmitted to the output shaft. The ratios are as follows:
1st gear, 2.84 to 1
2nd gear, 1.55 to 1
3rd gear, 1.00 to 1
4th gear, 0.70 to 1
Reverse, 2.32 to 1
- Members of the gearset are held or driven by a series of bands or clutches.
- The transmission uses two bands, two one-way roller clutches and four friction clutches.
