Cleaning & Inspection

  1. Wash all parts in clean solvent and dry them with compressed air. Do not use rags or water. Lint from rags may limit ATF flow after reassembly. Check all parts for burrs and scores. Replace assembly if damaged.
    NOTE: Valves which are slightly scored may be reused if they slide into the valve body under their own weight after cleaning and lubrication with fresh ATF. Minimal scoring will not affect transmission operation.
  2. Check all valve body springs for damage or collapsed coils. Some transfer plates are equipped with 3 sealing balls. See Figure . If transmission will not shift into 3rd gear, trouble may be caused by missing sealing ball.
  3. To install new sealing balls, place 3 mm diameter sealing ball on 8 mm diameter punch with small amount of grease and drive ball flush into hole of transfer plate.
