  • Nissan Altima
  • Nissan JX35
  • Nissan Maxima
  • Nissan Murano
  • Nissan Quest

Using the National 710631 seal helps address common transmission issues such as:

  • Preventing transmission fluid leaks around the torque converter
  • Reducing contamination ingress into the transmission system
  • Maintaining proper hydraulic pressure within the transmission
  • Minimizing premature wear of transmission components
  • Ensuring smooth torque converter operation

Installation Notes and Tips

When installing the National 710631 torque converter seal, ensure the housing bore and shaft surfaces are clean and free of debris. Proper alignment during installation is critical to avoid seal damage and ensure optimal performance. Use appropriate tools to press the seal evenly into place without distortion. Verify the seal lip orientation matches the clockwise-spiral design for correct fluid direction.
