Forward Clutch Assembly: Assembly
- Install the planetary assembly snap ring, if necessary.
- Make sure the planetary snap ring is oriented as shown.
- Install the T1 bearing onto the sun gear.
- Install the sun gear into the planet assembly with the T1 bearing facing down and the recessed part of the gear up.
- Install new O-ring seals onto the forward clutch piston.
- Lightly coat the O-ring seals with clean transmission fluid and install the forward clutch piston into the forward clutch drum.
- Install the forward clutch return spring.
- Install a new O-ring seal onto the forward clutch balance dam. Lightly coat the O-ring seal with clean transmission fluid.
- Align the marks made during disassembly and install the balance dam into the forward clutch drum.
- Using the special tool, slightly collapse the balance dam to install the retaining ring. Install the retaining ring.
- Install the new forward clutch plates, starting with the wave spring then a steel plate and alternating between friction and steel plates, and ending up with the pressure plate.
- Install the forward clutch plate snap ring.
- Install the forward clutch assembly into the special tool so the dial indicator fits into the opening of the snap ring.
- With the dial indicator set at zero, lift up on the steel pressure plate so it is against the select fit snap ring. Record this reading as reading A.
- Rotate the forward clutch assembly 180 degrees from the opening of the snap ring, take a second reading and record this reading as reading B.
Description Reading Reading A Reading B Add reading A to reading B for a total end clearance Divide the total reading by 2 for an average end clearance - 5.4L engine - 0.71-1.10 mm (0.028-0.043 in).
- If the free pack end clearance between the bottom of the snap ring and the top of the pressure plate is high, remeasure using a thicker select fit snap ring. If the free pack end clearance between the bottom of the snap ring and the top of the pressure plate is low, remeasure using a thinner select fit snap ring.
- Install the sun gear and planetary gearset into the forward clutch drum. Make sure it snaps and locks in place.
NOTE:
If a new planetary assembly is being installed, the new planetary assembly may not come with the snap ring installed.
NOTE:
Prior to releasing the special tool, make sure that the snap ring is fully seated.
NOTE:
All forward clutch plates, friction and steel are of a wave-type design.
NOTE:
If the final measurement is not within specification, install a new snap ring until the correct specification is achieved.
