Forward Clutch: Inspection

  1. Inspect clutch drum for scoring, wear, or other damage. Check clutch drum ball valve for free movement and ensure that drilling is clear. On E-Mode models, inspect all springs for wear or damage.
  2. On all other models, inspect diaphragm spring and piston for damage. Place diaphragm spring onto piston and ensure that top of spring reaches lower edge of snap ring groove. If not, replace spring.
    NOTE: Forward clutch piston sealing lips are vulcanized to piston. Replace entire piston if there is damage to sealing lip or if there is leakage past sealing lips.
  3. Use direct-reverse clutch inspection procedures to inspect lined and steel clutch plates. If new lined (internally splined) clutch plates are to be installed, soak them in ATF for 15 minutes prior to installation.
