Forward Clutch Assembly: Disassembly
NOTE:
Clutch plate quantity is model dependent based on engine displacement:
- 4.6L engine (Explorer, Mountaineer, Sport Trac, F-150)
- Four friction plates
- Five steel plates
- 5.4L engine (Expedition, Navigator, F-150)
- Five friction plates
- Six steel plates
- If the T2 thrust bearing is on the forward clutch assembly, remove it from the forward clutch assembly.
- Remove the front planetary carrier and sun gear from the forward clutch assembly.
- With a small screwdriver or a suitable pick inserted into the front planetary assembly, push on the retaining ring in 4 places while lifting up on the front planetary assembly.
- Remove the forward clutch pack snap ring.
- Remove and inspect the forward clutch steel and friction plates.
- If the plates are damaged, install a new forward clutch assembly.
- If no damage is indicated, the forward clutch may be reassembled.
- For correct alignment during assembly, make an identifying mark on the balance dam and the center part of the housing.

- Install the forward clutch on the front pump to remove the forward clutch piston. Apply a small amount of shop air to remove the piston.
- Remove and discard the inner and outer piston O-ring seals.
- Remove the sun gear from the planet assembly.
- Remove the T1 bearing from the planetary carrier.
- Remove the transmission fluid collector plate from the front planetary carrier.
- Clean and inspect the components of the forward clutch assembly for damage and install new components as necessary.
NOTE:
Inspect the forward clutch drum and the friction and steel plates for damage. Install new components as necessary.
