WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

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.
