Preventive Maintenance Tips

Preventive Maintenance Tips
  1. Regular Fluid Checks
    • Regularly check the transmission fluid level and condition. Clean, red fluid indicates a healthy transmission, while dark or burnt-smelling fluid suggests a problem.
  2. Scheduled Maintenance
    • Follow the manufacturer’s recommended maintenance schedule, including fluid changes and system inspections.
  3. Driving Habits
    • Avoid aggressive driving, which can strain the transmission. Use the correct gear for the speed and load conditions.
  4. Coolant System Maintenance
    • Ensure the vehicle’s cooling system is functioning properly to prevent overheating, which can damage the transmission.
  5. Listen to Your Vehicle
    • Pay attention to unusual noises, smells, or performance issues. Early detection can prevent minor issues from becoming major repairs.


Transmission issues can be complex and costly, but understanding the common problems and their solutions can help you manage and maintain this crucial component of your vehicle. Regular maintenance, attentive driving, and prompt repairs are key to ensuring your transmission’s longevity and reliability.
