Installation Notes
Inspect the shift-cable bellows and seating surfaces for splits, corrosion or damage before fitting the clamp. Install the band in the correct position and orientation, using the service-manual procedure to avoid damaging the bellows or restricting movement.
Parts Desk Insight
The two ends of the shift-cable bellows use different retaining hardware. Match the worm-gear clamp location rather than ordering either clamp interchangeably.
