Power is transmitted from the torque converter to the Ravigneaux geartrain components through the input shaft and forward clutch cylinder.
- The geartrain contains a Ravigneaux planetary set connected by dual pinion gears.
- By holding or driving certain components of the gearset, four forward ratios and one reverse ratio are obtained and transmitted to the output shaft. The ratios are as follows:GEAR RATIO CHART
Gear Ratio 1st 2.84 to 1 2nd 1.55 to 1 3rd 1.00 to 1 4th 0.70 to 1 Reverse 2.32 to 1 - Components of the geartrain can be held by bands or clutches and driven by clutches only.
This transmission uses:
- Two bands.
- Two one-way clutches (one roller, one mechanical diode).
- Four friction clutches.
