Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.
Disconnect the battery to ensure safety while working on electrical components.

2. CVT Fluid Change

Tools Required: Socket set, fluid pump, drain pan, funnel
Remove the CVT fluid drain plug and allow the old fluid to drain completely into the drain pan.
Replace the drain plug and torque to manufacturer specifications.
Using the fluid pump, add new CVT fluid through the fill hole until the correct level is reached (check the owner's manual for the specific fluid type).
Start the engine and let it idle; shift through all gears to circulate the new fluid, then recheck the fluid level and top off if necessary.

3. Inspect and Replace CVT Filter (if applicable)

Tools Required: Socket set, replacement filter (if applicable)
Locate the CVT filter; remove the retaining clips or bolts.
Carefully remove the old filter and replace it with a new one, ensuring proper seating.
Reattach any clips or bolts securely.

4. TCM Reset (if necessary)

Tools Required: OBD-II scanner
Connect the OBD-II scanner to the vehicle.
Follow the scanner instructions to reset or reprogram the TCM if any fault codes were present and the issue persists after fluid change.

5. Test Drive

Conduct a test drive to ensure that the shuddering issue has been resolved. Monitor for any unusual behavior during acceleration.
