Reverse Reaction Drum: Inspection
WARNING: This page does not describe the selected car, but rather 43 other vehicles, including the 2003 Pontiac Montana, 2003 Pontiac Grand Prix, 2003 Pontiac Bonneville, 2003 Pontiac Aztek, and 2003 Oldsmobile Silhouette. However, it is still accessible from the selected car via links, so may be relevant.
- Inspect for damaged 2nd clutch and reverse reaction drum splines. Original 2nd clutch and reverse reaction drums have splines with 25-degree sides and have tendency to strip. New design 2nd clutch and reverse reaction drum kit (GM P/N 24213402) have splines with 10-degree sides.
- Inspect reverse reaction drum for cracks, damaged splines or distortion. See Figure. Replace drum if necessary.
