Geartrain

Power is transmitted from the torque converter (7902) to the Ravigneaux geartrain components through the input shaft and stub 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 (7060) . The ratios are as follows:

• Members of the gearset are held or driven by a series of bands or clutches.
• The AODE uses:
  • Two bands
  • Two one-way clutches
  • Four friction clutches

The application of these bands and clutches is similar to the previous AOD transmission.

Many components, including the case, have been modified to house the new aspects of the AODE.
