Solution

1. Preparation

Gather tools and parts needed for inspection and repair.
Elevate the vehicle using a jack and secure with jack stands.
Allow the engine to cool down to prevent burns.

2. Inspect and Identify Leaks

Use a clean cloth to wipe any fluid from suspected areas and note where it reappears.
Check the CVT pan bolts for proper torque (approximately 8-10 Nm) and tighten if necessary.
If the fluid level is low, add the appropriate CVT fluid as specified in the owner’s manual.

3. Replace Damaged Components

If leaks are found in the fluid lines, disconnect the lines using a wrench.
- Tools Required: Wrench set, fluid catch pan.
Replace any damaged lines with new OEM parts.
For leaking seals or gaskets, remove the CVT pan:
- Drain the fluid into a catch pan.
- Remove the pan bolts and gently pry the pan away.
- Replace the gasket with a new one and reassemble the pan.
- Tools Required: Socket set, gasket scraper, torque wrench.

4. Refill and Test

Refill the CVT with manufacturer-recommended fluid through the fill plug.
Start the engine and let it idle, then shift through all gears to circulate the fluid.
Check for leaks around the repaired areas.
