Why Choose the Correct Fluid

Using the right transmission fluid isn’t just a suggestion, it’s vital for several reasons:

  • Component Protection: Correct fluid types contain additives designed specifically for your transmission, protecting gears, clutches, and other vital parts from excessive wear.
  • Prevent Damage: Using the wrong fluid can lead to increased friction, overheating, leaks, and potential long-term failure, resulting in expensive repairs.

Transmission Fluid Maintenance

Beyond choosing the right fluid, regular maintenance is key:

  • Check Fluid Levels: Refer to your owner’s manual for the recommended inspection interval and procedure. Low fluid levels can cause serious problems.
  • Fluid Condition: Look for discoloration, burnt smells, or debris, which may indicate issues. If your fluid looks compromised, consult a mechanic.

At dealerships, auto parts stores, or online retailers specializing in Ford parts.

Can I change transmission fluid myself?

It’s possible, but may require special tools. Consult your owner’s manual and assess your mechanical skills.
