Solution
1. Preparation
  • Tools Required: OBD-II scanner, socket set, torque wrench, fluid pump, transmission jack.
  • Lift the vehicle using a jack and secure it with jack stands. Ensure the engine is off and cooled down.
2. Fluid Change
  • Sub-steps:
    1. Remove the transmission drain plug and allow the old fluid to drain completely into a suitable container.
    2. Replace the drain plug and torque it to the manufacturer’s specifications (consult service manual for exact torque value).
    3. Refill the transmission with new, manufacturer-approved CVT fluid using a fluid pump until the fluid is at the correct level as per the dipstick or service guide.
3. Inspect and Replace Components
  • Sub-steps:
    1. Remove the transmission belt cover as per service manual instructions.
    2. Visually inspect the CVT belt and pulleys for signs of wear, such as fraying or scoring.
    3. If any damage is noticed, replace the CVT belt and/or pulleys as necessary. Properly align components during installation.
    4. Reattach the belt cover securely.
4. Electrical Inspection
  • Sub-steps:
    1. Inspect all wiring and connectors related to the CVT for signs of corrosion or damage.
    2. Clean or replace any corroded connectors.
    3. Test the CVT control module connections and replace the module if it is faulty.
