Transmission fluid checks are a must for Ford F-150 maintenance

Although the new Ford F-150 boasts a number of unique features, like the Power Boost, Zone Lighting System, and Trailer Backup Assist, to name a few, it relies on transmission fluid for safety and performance just as much as any other modern vehicle.

Time and time again, we’ve recommended that customers keep an eye on the level and the condition of their transmission fluid (see: How Do I Check My Transmission Fluid Level?, Transmission Fluid Diagnosis and Changing Transmission Fluids).

In fact, if you want to control vehicle maintenance costs, it is essential that you keep your transmission fluid topped up and in good condition, as transmission components are some of the most expensive to repair and replace.

Accordingly, in the past, Ford F-150 manufacturers recommended checking your transmission fluid on a regular basis.

However, that’s easier said than done for some drivers, who may be surprised to find that the Ford F-150 no longer has a standard transmission dipstick under the hood. If you’re driving a newer model with a “Sealed-for-life” transmission, read on to learn more about what that means, or contact a local Ford transmission specialist to book a free inspection and service straight away.

Why does the Ford F-150 no longer have a transmission dipstick?

Many modern vehicles are designed without standard transmission dipsticks, opting instead to use a “sealed-for-life” transmission that does not require the same upkeep as older vehicles. This can be seen in the new Ford F-150, Canada’s best selling truck, which made the switch to sealed transmissions in 2017 when they rolled out their new 10-speed transmission, the 10R80.

But why does the Ford F-150 no longer have a transmission dipstick? In short, it is because the new transmission system in the Ford F-150 requires less frequent care, and when the time comes for maintenance and repairs, it is meant to be left to professionals.

According to the Ford F-150 2022 owner’s manual, the automatic transmission:

  • Should only be checked and changed by an authorized dealer or transmission specialist
  • Does not consume fluid, and thus does not require regular top-ups from drivers
  • Does not require supplemental transmission fluid additives, treatments, or cleaning agents, all of which can negatively affect transmission operating and result in damage to internal transmission components

Do-it-yourself transmission service attempts and fluid top-ups could result in overfilling, cavitation, oil starvation, lack of lubrication, fluid leakages, accelerated wear-and-tear, and transmission system failure. For best results, find a Mister Transmission near you.

How to access the screw-in dipsticks on the Ford F-150

Should you need to access the transmission dipstick for any reason, you won’t find it under the hood of your Ford F-150, at least not if you’re driving a model released after 2017.

The 10R80 uses a unique screw-in dipstick that can only be accessed from underneath the vehicle, which may require special skills or tools. This dipstick threads into the passenger side of the transmission case in a location similar to where dipstick tubes used to fit into rear-wheel drive transmissions.

What’s more, not all screw-in dipsticks are the same in newer Ford F-150s. Some are marked off with letters; others use numbers, listed 1 to 6. Because the 10R80 is used in multiple applications, and the driveline angle varies with each, the correct level of the dipstick will not always be in the center of the crosshatch where you’d expect. In fact, in the 2018 Ford F-150, the correct fluid level actually appears quite close to the bottom, which can be confusing for some drivers trying to get a proper reading.

The correct procedure for checking your transmission fluid is as follows:

  • Drive your Ford F-150 until the transmission fluid reaches a temperature of 206° to 215°
  • Either lift your vehicle on a hoist or crawl underneath to access to screw-in dipstick
  • Caution: The exhaust will be hot, so you may need to wear gloves or long sleeves to avoid burns
  • The 10R80 screw-in dipstick uses a 19mm nut—use a socket or end wrench to loosen it
  • Consult the owner’s manual or ask a Mister Transmission expert which fluid reading to use

By working with a local Mister Transmission, you’re guaranteed easy access, accurate readings, and quality service in a fraction of the time, with none of the hassle, safety concerns, or risk of potentially voiding your vehicle warranty.

When to book a transmission fluid service for your Ford F-150

As per the Ford F-150 2020 owner’s manual, you should book a transmission fluid service for your vehicle if:

  • You notice transmission slips
  • Your transmission shifts slowly
  • You spot signs of transmission fluid leaks

Additionally, you should book a transmission service after approximately 240,000km.

I have nothing but good...
Paul
I have nothing but good things to say about Mister Transmission Pickering. We were experiencing transmission problems with our Mini-van. After calling around several local shops in the area, Mister Transmission appeared to stand out from the rest of the shops so I went with them. I dealt with Ken and Chris during my visit. I was advised of what repairs my van needed. The price was very reasonable, Ken even offered to drive me home so I could continue on with my day while the repairs were being done. All in all I had a great experience with Mister Transmission. I am very happy with the time it took for the repairs to complete as well the cost of the repair was reasonable and well within my price range. Highly Recommended!

Victor S
To fix the tranny of my old car was expected of him because he is running the same Mister Transmission place for decades. But what wasn’t expected of him to tune my 40 yr old car to perfection, and fix my leaky carburetor. Changing the upper arms and wheel bearings were also extra. So if you look for something more than just your transmission, I doubt you can find a better mechanic than Kenny at Mister Transmission on Woodbine at Dennison. You’ll be seriously satisfied, and more than pleasantly impressed!

I had an issue with my subaru, and was given limited options in stratford to fix it. I took it to Gary and his team, and not only did he give me options for repair, he was very straightforward and thorough with his explanation on the problem and the best way to solve it. I would highly recommend anyone with transmission issues to take it here, even if only for a second opinion
