• Contamination entry from dirt, dust, and moisture
• Wear-related sealing loss around the shift shaft interface
• Incorrect seal sizing during transmission service
• Replacement needs on select Suzuki Grand Vitara, Vitara, and Sidekick models

Installation Notes and Tips

Verify bore diameter, outside diameter, and seal width before installation to confirm the seal matches the transmission case and shaft dimensions. Clean the sealing surface thoroughly, inspect the shaft for wear or scoring, and install the seal squarely to avoid distortion. Confirm vehicle application by year and model before ordering, especially when sourcing SS3946 for Suzuki Grand Vitara, Vitara, or Sidekick service.
