Sub-step 3: Allow old fluid to drain completely.
Sub-step 4: Replace the transmission filter if applicable.
Sub-step 5: Reinstall the drain plug and torque to manufacturer specifications.
Sub-step 6: Use a transmission fluid pump to refill new CVT fluid through the dipstick tube or designated fill port.
Sub-step 7: Start the engine and allow it to reach operating temperature, then check fluid levels and top off as necessary.

4. Belt Inspection

Sub-step 1: If slipping persists, remove the CVT cover to access the belt.
Sub-step 2: Inspect the belt for signs of wear, fraying, or glazing.
