Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Forward Drive System
The forward drive system consists of the following:
- Direct clutch assembly
- Forward clutch assembly
- Forward ring gear
- Forward planetary assembly
- Forward/reverse input shell assembly
The direct clutch grobbed cylinder contains the following:
- A bonded lip seal piston
- A direct clutch return spring
- A direct clutch bonded lip seal balance piston
These components are held in place by a snap ring to the direct clutch cylinder.
The direct clutch separator plates and pressure plate are splined to the direct clutch cylinder and held by a snap ring. The direct clutch friction internally splined plates mate with the grobbed splines on the forward clutch cylinder. The forward clutch has a bonded lip seal piston, a beveled design return spring and a bonded lip seal balance piston which are held to the cylinder with a snap ring.
The forward clutch cushion wave spring is splined to the cylinder, as are the separator plates and pressure plate and are held together with a selective snap ring. The forward clutch friction plate is splined to the forward ring gear.
Positioned on the center support hub is a thrust bearing to locate the forward clutch cylinder. There is a thrust bearing positioned between the direct clutch cylinder and the forward clutch cylinder. There is also a thrust bearing positioned between the forward clutch cylinder and the forward ring gear and between the forward planet and the forward clutch cylinder. There is a thrust washer separating the forward carrier from the forward ring gear hub. The 6 gear forward planet has a black, phenolic lube dam which snaps onto the rear of the carrier body. Into the center of the input shell is the forward/reverse sun gear positioned by a spacer and held in place by a retaining ring.
