Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Scan for Error Codes

Connect the OBD-II scanner to the diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Read and record any error codes related to the transmission.

3. Inspect Transmission Fluid

Locate the transmission dipstick (if equipped) or check the fill plug.
Pull out the dipstick or remove the fill plug and wipe it clean.
Reinsert, then remove again to check fluid level. The level should be within the marked range.
Assess fluid condition: it should be a bright red color and should not have a burnt smell. If it is dark or smells burnt, fluid replacement may be necessary.

4. Check for Fluid Leaks

Inspect the area under the vehicle for any signs of transmission fluid (red or pink fluid).
Examine the transmission pan, seals, and hoses for any cracks or damage.

5. Test Drive Assessment

Take the vehicle for a short test drive, paying attention to acceleration and shifting.
Note any hesitation, slipping, or unusual noises during acceleration.
Verify if the check engine light remains illuminated.

6. Fluid Temperature Check

Use a scan tool capable of reading live data to monitor the CVT fluid temperature.
Ensure the temperature is within the operating range specified in the owner's manual (typically between 150°F to 200°F).
