Solution

1. Preparation

Gather tools: OBD-II scanner, transmission fluid dipstick or gauge, fluid catch pan, socket set, and torque wrench.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Fluid Change (if necessary)

Drain Old Fluid
1. Place a fluid catch pan under the transmission drain plug.
2. Remove the drain plug and allow the old CVT fluid to completely drain.
3. Replace the drain plug and torque it to the manufacturer's specifications.
Refill with New CVT Fluid
1. Access the CVT fluid fill port (refer to the owner’s manual for location).
2. Use a funnel to add new CVT fluid that meets Ford specifications.
3. Start the engine and let it run for a few minutes, then check the fluid level with the dipstick.

3. Replace CVT Components (if diagnosing mechanical issues)

Remove the Transmission Pan
1. Support the vehicle securely on jack stands.
2. Remove any bolts securing the transmission pan and carefully lower it.
3. Inspect the filter and replace it if clogged or damaged.
Inspect and Replace Belts/Pulleys
1. Remove the belt covers and inspect for wear or cracks.
2. Use a socket set to remove the pulleys if they are damaged and replace with OEM parts.

4. Reassemble and Test

Reinstall any removed components in reverse order, ensuring all bolts are torqued to specifications.
Conduct a test drive to ensure the transmission operates smoothly without slipping or abnormal noises.
