Main Geartrain Components

Forward Clutch Cylinder and Shaft

The forward clutch cylinder and shaft (7F207) transfers speed and torque from the converter turbine to the geartrain. This shaft is splined to the turbine on one end and to the forward clutch cylinder and stub shaft on the other end.

Stub Shaft

The stub shaft transfers power from the turbine shaft to the planet carrier (through the direct clutch) during third and fourth gear operation.

Compound Planetary Gearset

The planetary gearset in the transmission is a Ravigneaux-type set consisting of the following components:

• Primary sun gear (7A399).
• Reverse clutch gear and shell (7A019).
• A pinion carrier.
• Long and short pinions.
• Ring gear (7A153).

Members are driven or held to produce four forward gear ratios plus one reverse ratio.

Output Shaft

The output shaft (7060) provides torque to the propeller shaft and rear axle assembly (4200). It is driven by the ring gear of the planetary gearset.
