- Secure the cover back in place with the appropriate bolts.

3. Check and Top-Up Transmission Fluid

Locate the Transmission Dipstick
- Remove the dipstick while the engine is running to check fluid level.
Inspect Fluid Condition
- Fluid should be a clear red color; if dark or burnt, consider a fluid change.
Add Transmission Fluid
- Use the recommended type (consult the owner's manual) and fill to the proper level.

4. Inspect Power Steering Fluid

Locate Power Steering Reservoir
- Check fluid level and condition.
Add Power Steering Fluid
- If low, add fluid to the appropriate level using the recommended type.
