Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Tools Required: OBD-II scanner, socket set, transmission fluid dipstick.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Using the dipstick, check the fluid level; add fluid if low.
2. If the fluid appears burnt or dirty, drain the transmission fluid by removing the drain plug.
3. Replace with the manufacturer-recommended CVT fluid (typically Toyota CVT Fluid FE).
4. Reinstall the drain plug and torque to the manufacturer specifications.

3. Inspect and Repair CVT Components

Sub-steps:
1. Remove the CVT cover to access the belt and pulleys.
2. Inspect the CVT belt for wear, cracks, or glazing; replace if necessary.
3. Check the pulleys for damage or excessive wear; replace if needed.
4. Reassemble the CVT cover, ensuring all bolts are properly torqued.

4. Clear Error Codes

Use the OBD-II scanner to clear any transmission-related error codes after repairs.
