Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, torque wrench, transmission fluid, replacement filter (if applicable), and a fluid pressure gauge.
Ensure the vehicle is parked on a level surface, and the engine is cool.

2. Fluid Check and Replacement

Fluid Level Check:
1. Locate the CVT dipstick (if equipped) or use the fill plug.
2. Remove the dipstick or fill plug and check the fluid level. Add CVT fluid as necessary to reach the proper level.
Fluid Replacement:
1. Place a drain pan under the transmission pan.
2. Remove the transmission pan bolts using a socket wrench. Carefully lower the pan to avoid spilling.
3. Remove the old filter (if equipped) and clean the mating surface.
4. Install the new filter, ensuring it is seated properly.
5. Reinstall the transmission pan, tightening the bolts to the specified torque (typically 7-10 ft-lbs).
6. Refill the transmission with the appropriate CVT fluid through the dipstick or fill plug.

3. Inspect and Repair Components

Inspect Transmission Components:
1. Check for any damaged components such as the CVT belt or pulleys.
2. If damage is found, follow the manufacturer’s specifications for replacement.
Repair or Replace TCM:
1. If the TCM is diagnosed as faulty, disconnect the battery and remove the TCM from its mounting.
2. Install the new TCM following the manufacturer’s guidelines and reconnect the battery.
