WARNING: This page does not describe the selected car, but rather 22 other vehicles, including the 2005 Lexus SC 430, 2005 Lexus IS 300, 2005 Lexus GS 430, 2005 Lexus GS 300, and 2004 Lexus SC 430. However, it is still accessible from the selected car via links, so may be relevant.
  1. Clean all components (except discs) with solvent. Dry with compressed air. Inspect plates and discs for flaking or burnt areas. Ensure check ball does not allow air to bleed through piston.
  2. Measure inside diameter of clutch drum bushing and planetary gear bushing. Maximum diameter for overdrive direct clutch drum bushing is 1.067" (27.11 mm). Maximum diameter for overdrive planetary gear bushing is .444" (11.27 mm). See Fig 2 and Fig 3 . Replace components if damaged or not within specifications.
  3. Measure planetary pinion gear thrust clearance. See Fig 4. Standard clearance should be .008-.024" (.20-.61 mm). Maximum clearance is .039" (1.00 mm). If clearance is not within specifications, replace planetary gear assembly. Check OD direct clutch return spring free length. Include spring seat in measurement. Standard free length is .622" (15.80 mm).
