1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical shorts.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Check the fluid level; if low, add the correct type of transmission fluid (refer to owner's manual).
3. If the fluid is dirty or burnt, drain the transmission fluid via the drain plug.
4. Replace with new transmission fluid, ensuring it meets Ford specifications.
Tools Required: Transmission fluid pump, socket set.
