Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Transmission Fluid

Tools Required: Dipstick, funnel, transmission fluid.
Remove the dipstick and check the fluid level. If low, add the recommended CVT fluid as per the owner’s manual.
If fluid is dark or has a burnt smell, it may need to be replaced.

3. Replace Transmission Fluid

Tools Required: Fluid pump, catch pan, socket set.
Place a catch pan under the transmission drain plug.
Remove the drain plug and allow old fluid to completely drain.
Reinstall the drain plug and refill with new CVT fluid using a fluid pump through the dipstick tube.
Check the fluid level again after running the engine for a few minutes.

4. Inspect and Replace Components

Tools Required: Socket set, screwdrivers, transmission jack.
If the CVT belt or pulleys are damaged, remove the transmission from the vehicle using a transmission jack.
Disassemble the CVT by removing the appropriate bolts and clips.
Replace any damaged components and reassemble the CVT.
Reinstall the transmission carefully and ensure all connections are secure.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and allow it to idle for a few minutes.
Test drive the vehicle, paying attention to the transmission's performance.
