Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety while working on the transmission.

2. Change Transmission Fluid and Filter

Sub-steps:
1. Lift the vehicle securely using jack stands.
2. Drain the old transmission fluid by removing the transmission pan bolts and allowing the fluid to drain into a pan.
3. Remove the transmission filter from its housing.
4. Clean the transmission pan and remove the old gasket material from the pan and housing.
5. Install the new transmission filter in place.
6. Apply a new gasket or sealant on the transmission pan.
7. Reinstall the transmission pan and torque the bolts to the manufacturer specifications (typically 10-12 ft-lbs).

3. Inspect and Replace CVT Components (if necessary)

Sub-steps:
1. Remove the CVT belt and pulley assembly if wear is detected.
2. Inspect the pulleys for scoring or damage.
3. Replace the CVT belt and pulleys if any damage is found.
4. Reassemble all components, ensuring everything is correctly aligned and secured.

4. Refill Transmission Fluid

Sub-steps:
1. Use a funnel to fill the transmission with new CVT fluid (use manufacturer-recommended fluid type, usually Mercon LV).
2. Start the engine and let it idle while shifting through all gears to circulate the fluid.
3. Check the fluid level with the dipstick, adding more fluid as necessary.
