Essential Information

  • If you’ve recently had your transmission fluid changed, it’s a good idea to check the level again after driving for a short distance.
  • If your truck is experiencing issues like slipping gears, rough shifting, or a burning smell, it’s essential to check the transmission fluid level immediately.
  • If you see any metal shavings or other debris in the fluid, it’s a sign of wear and tear on the transmission.

The transmission in your 2018 F150 is a vital component that allows your truck to shift smoothly and efficiently. Keeping the transmission fluid clean and at the proper level is crucial for its longevity and performance. This comprehensive guide will walk you through the process of checking the transmission fluid in your 2018 F150, ensuring you can keep your truck running strong for years to come.

Why Checking Transmission Fluid is Important

Transmission fluid acts as a lubricant, coolant, and cleaner for your transmission. It helps to reduce friction between moving parts, dissipate heat, and prevent wear and tear. Over time, the fluid can become contaminated with debris and lose its effectiveness. Low fluid levels can lead to overheating, slipping gears, and even transmission failure.

When to Check Your Transmission Fluid

While your 2018 F150’s transmission fluid is designed to last a long time, it’s still important to check it periodically. Here’s a good rule of thumb:

  • Regularly: Check the fluid level at least once a year or every 3,000 miles, whichever comes first.
  • After a Transmission Service: If you’ve recently had your transmission fluid changed, it’s a good idea to check the level again after driving for a short distance.
  • If You Notice Any Problems: If your truck is experiencing issues like slipping gears, rough shifting, or a burning smell, it’s essential to check the transmission fluid level immediately.

Gathering Your Supplies

Before you start, you’ll need a few basic supplies:

  • Clean Rags: To wipe up any spills or drips.
  • Gloves: Protect your hands from the transmission fluid, which can be messy and greasy.
  • Coolant Recovery Bottle: An empty coolant recovery bottle or a similar container can be used to check the fluid level.

Finding the Transmission Dipstick

The transmission dipstick is located on the passenger side of the engine compartment, near the firewall. It’s usually a long, metal rod with a yellow or orange handle.

  • Locate the Dipstick: Open the hood and locate the dipstick. It might be tucked away behind other parts, so you may need to move some hoses or components to get a clear view.
  • Identify the Correct Dipstick: If there are multiple dipsticks, make sure you’re using the one for the transmission. The dipstick might have markings or labels to differentiate it.

Checking the Transmission Fluid Level

Here are the steps to check your transmission fluid level:

1. Warm Up the Engine: Start the engine and let it idle for a few minutes to warm up the transmission fluid. This ensures the fluid is at the correct temperature for an accurate reading.
2. Pull Out the Dipstick: Gently pull out the dipstick and wipe it clean with a rag.
3. Reinsert and Remove Again: Reinsert the dipstick all the way in, then pull it out again.
4. Check the Fluid Level: The fluid level should be between the “Full” and “Add” marks on the dipstick. If the fluid level is below the “Add” mark, you may need to add more fluid.

Interpreting the Transmission Fluid Condition

Once you’ve checked the fluid level, it’s important to also inspect the condition of the fluid itself.

  • Color: New transmission fluid should be a bright red or pink. If the fluid is dark brown or black, it’s likely contaminated and needs to be changed.
  • Smell: Transmission fluid should have a slightly sweet smell. If it has a burnt or acrid odor, it’s a sign of overheating and potential damage.
  • Presence of Debris: If you see any metal shavings or other debris in the fluid, it’s a sign of wear and tear on the transmission.

Adding Transmission Fluid

If the transmission fluid level is low, you can add more fluid. However, it’s important to use the correct type of fluid for your 2018 F150.

  • Check Your Owner’s Manual: The owner’s manual will specify the correct type of transmission fluid for your vehicle.
  • Consult a Mechanic: If you’re unsure about the correct type of fluid, consult a qualified mechanic. Using the wrong type of fluid can damage your transmission.

When to Take Your F150 to a Mechanic

If you notice any of the following signs, it’s a good idea to take your F150 to a mechanic for inspection:

  • Low Transmission Fluid Level: If you consistently have to add transmission fluid, there may be a leak or other issue that needs to be addressed.
  • Dark or Burnt Fluid: This indicates that the fluid is contaminated and needs to be changed.
  • Slipping Gears: A slipping transmission is a serious problem that requires immediate attention.
  • Rough Shifting: If your truck shifts roughly or with a delay, it could be a sign of a transmission problem.
  • Burning Smell: A burnt smell coming from the transmission is a sign of overheating and potential damage.

Beyond the Basics: Understanding Transmission Fluid Changes

While checking the transmission fluid is essential, it’s not a substitute for regular fluid changes. Here’s why:

  • Fluid Degradation: Over time, transmission fluid breaks down and loses its effectiveness. This can lead to wear and tear on the transmission, resulting in costly repairs.
  • Contamination: Even if you don’t notice any problems, the fluid can become contaminated with debris, which can also damage the transmission.

The Importance of Regular Transmission Fluid Changes

For optimal performance and longevity, it’s recommended to have your transmission fluid changed at regular intervals.

  • Consult Your Owner’s Manual: The owner’s manual for your 2018 F150 will provide specific recommendations for transmission fluid change intervals.
  • Consider Your Driving Habits: If you frequently tow heavy loads or drive in harsh conditions, you may need to change your transmission fluid more often.

Taking Care of Your Transmission: A Final Word

Checking your transmission fluid regularly is an essential part of maintaining your 2018 F150. By following the steps outlined in this guide, you can ensure your truck’s transmission is operating smoothly and efficiently. Remember, if you notice any problems with your transmission, don’t hesitate to consult a qualified mechanic. Taking care of your transmission today can save you from costly repairs down the road.
