How To Check Transmission Fluid Ford F150 2021

Checking your 2021 Ford F-150's transmission fluid is crucial for maintaining its health and longevity. Low or dirty fluid can lead to serious transmission problems, costly repairs, and even complete failure. This guide provides a step-by-step process for checking your F-150's transmission fluid. Remember, safety first! Always refer to your owner's manual for specific instructions and safety precautions for your vehicle.

What You'll Need

Before you begin, gather these items:

Clean rags or paper towels: To wipe up any spills.
Gloves: Protect your hands from the fluid.
Jack and jack stands (optional but recommended): Provides easier access and safer working conditions.
Owner's manual: Consult for specific instructions and torque specifications.

How to Check Your 2021 Ford F-150 Transmission Fluid

Important Note: The 2021 Ford F-150, depending on the transmission type (10-speed automatic is common), may not have a traditional dipstick. Some models use a fill plug as the check point. Consult your owner's manual to verify your F-150's transmission fluid check method. This guide covers both scenarios.

Method 1: Dipstick Method (if applicable)

Prepare your vehicle: Park on a level surface, engage the parking brake firmly, and turn off the engine. Allow the engine to cool down completely before checking the fluid. Hot transmission fluid can cause burns.
Locate the dipstick: Open the hood and locate the transmission dipstick. It's usually marked with "Transmission Fluid" or a similar label.
Remove and wipe the dipstick: Remove the dipstick, wipe it clean with a rag, and reinsert it fully.
Remove and check the fluid level: Remove the dipstick again. The fluid level should be between the minimum and maximum marks on the dipstick. Note the color and condition of the fluid. It should be reddish-pink and relatively clear. Dark brown or black fluid indicates the need for a fluid change.
Replace the dipstick: Securely replace the dipstick.

Method 2: Fill Plug Method (if applicable)

Prepare your vehicle: As with the dipstick method, park on a level surface, engage the parking brake firmly, and turn off the engine. Let the engine cool completely.
Locate the fill plug: Consult your owner's manual to locate the transmission fluid fill plug. It's usually located on the transmission itself.
Check the fluid level: With the engine running and warmed up to operating temperature, use a long, thin tube or a turkey baster to carefully draw some fluid from the fill plug.
Check the condition and level of the fluid: Observe the color and consistency. Dirty or low fluid needs attention. Your owner's manual might specify a particular procedure for determining the fluid level using this method, which often involves measuring the amount extracted.
Replace the fill plug: Securely replace the fill plug.

What to Do if the Fluid is Low or Dirty

If the fluid level is low, you will likely need to consult a mechanic. Adding fluid yourself to a low transmission is risky if you do not understand the proper procedure. Dirty fluid always necessitates a professional fluid change or flush.
