WARNING: This page is about a different car, the 2007 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
- Install the new coast clutch piston inner and outer seal.
- Install the coast clutch piston into the special tool.
- Inspect the coast clutch components for damage or wear. Install new as necessary.
- Inspect the drum band surface, bushing and thrust surfaces for scores. Minor scores may be removed with a crocus cloth. Badly scored parts must be installed as new.
- Inspect the clutch piston bore and the clutch piston and the piston inner and outer bearing surfaces for scores.
- Check the fluid passages for obstructions. All fluid passages must be clean and free of obstructions.
- Inspect the clutch plates for wear, scoring and fit on the clutch hub serrations.
- Inspect the clutch pressure plate for scores on the clutch plate surface. Check the clutch release spring(s) for distortion.
- Verify the check ball in the front band brake and coast clutch drum is free to move and clear of debris.
- Install the coast clutch piston into the front band brake and coast clutch drum.
- Carefully remove the coast clutch piston from the special tool.
- Install the coast clutch piston springs.
- Install the 20 coast clutch piston springs.
- Position the coast clutch piston spring retainer on the coast clutch piston springs.
- Using the special tool, install the coast clutch piston spring retainer ring.
- Relieve the direct clutch spring tension and remove the special tool.
- When installing friction plates, the word TOP should face up. If reusing plates, grooves must be installed clockwise. Install the coast clutch disc pack.
- Install the 2 steel clutch plates and 2 friction clutch plates in alternating order starting with a steel clutch plate.
- Install the coast clutch pressure plate.
- Install the clutch pressure plate.
- Install the original coast clutch retaining ring.

NOTE:
The lip seals must be positioned as shown. Care must be taken to prevent rollover of the lip seal.
NOTE:
Lubricate the coast clutch piston inner and outer seal.
CAUTION:
Care must be taken to prevent damage to the seals during installation.
CAUTION:
Do not fully compress the special tool or damage to the coast clutch piston spring retainer may occur.
CAUTION:
Coast clutch friction plates are directional and must be installed with grooves clockwise (I.D. to O.D.). The word TOP should face up. Improper installation can result in transmission damage.
NOTE:
If new clutch plates are being used, they should be soaked in clean automatic transmission fluid before assembly.
NOTE:
The retaining ring is select fit.
WARNING:
When using compressed air, never let air pressure exceed 138 kPa (20 psi) and always wear safety glasses. Compressed air may cause foreign material or parts to become airborne. Failure to follow this instruction may result in serious personal injury.
NOTE:
The coast clutch piston is applied with air pressure and released when the air is removed.
