Revamp Your Engine’s Health with Transmission Fluid in Oil to Clean Lifters

Published by Dustin Babich on

Transmission fluid in oil can be used to clean lifters, as it contains detergents that help remove deposits. The detergents in transmission fluid can dissolve buildup on lifters, resulting in smoother engine performance.

This method should only be used as a temporary solution, and is not a substitute for regular oil changes and maintenance. Engines are the heart of vehicles, and it is crucial to keep them running smoothly for optimal performance. Lifters are one of the most important components of an engine, as they are responsible for maintaining valve lash and ensuring smooth operation of the valvetrain.

Over time, lifters can become dirty or clogged with deposits, which can cause them to malfunction and affect engine performance. While regular oil changes and maintenance can help prevent buildup on lifters, sometimes additional cleaning is necessary. One option is to use transmission fluid in the oil as a temporary cleaning solution. In this article, we will explore the pros and cons of using transmission fluid for this purpose, as well as provide some tips for maintaining lifter cleanliness in the long run.

What Is Transmission Fluid And Why Is It Used In Engine Oil?

Transmission fluid is a specialized oil used in automatic transmissions for lubrication and cooling purposes. It also serves to transmit power from the engine to the wheels. Due to its unique properties, it can be used in engine oil as well.

Adding transmission fluid to engine oil can help clean lifters, which are responsible for the precise firing of the engine. Clean lifters can result in improved engine performance and longevity. This method is especially useful for engines that have been neglected or haven’t been serviced in a while.

With regular maintenance and the use of transmission fluid in engine oil, car owners can ensure their vehicles run smoothly and efficiently.

Signs Of Dirty Lifters In An Engine

Dirty lifters in an engine are a major concern for car owners. One of the warning signs is tapping or knocking noises coming from the engine. These noises may be particularly noticeable when the engine is running at low speeds.

In addition to the noises, reduced engine performance may also be a tell-tale sign of dirty lifters in an engine. One option for repairing dirty lifters is to add transmission fluid to the engine oil. Transmission fluid contains detergents that can help remove sludge and other contaminants from the lifters.

Benefits Of Using Transmission Fluid In Engine Oil To Clean Lifters

Adding transmission fluid to engine oil can clean lifters, resulting in a range of benefits. Improved engine performance is one of the most notable, with the transmission fluid’s cleaning properties helping to keep the engine running smoothly. As lifters become dirty, they can cause increased engine noise and reduced fuel efficiency.

By using transmission fluid, the lifters can be kept clean, reducing noise and increasing fuel efficiency. This, in turn, can save money on gas and improve overall performance. It’s important to note that transmission fluid should only be added to the engine oil in small quantities and should not be used as a replacement.

Instead, it should be used as a cleaning agent to help keep the lifters functioning efficiently.

How To Add Transmission Fluid To Engine Oil To Clean Lifters

Adding transmission fluid to your engine oil can help clean lifters. To get started, gather the necessary supplies including transmission fluid, engine oil and a funnel. First, ensure your vehicle is on a level surface and the engine is off.

Next, remove the transmission dipstick and insert the funnel into the dipstick tube. Pour the transmission fluid into the funnel, making sure to pour it slowly. Then, add the engine oil to the proper level. It is important to take safety precautions like wearing gloves and eye protection.

This tip can help clean the lifters and improve engine performance. Remember to always consult your owner’s manual for specific instructions.

Frequently Asked Questions Of Transmission Fluid In Oil To Clean Lifters

What Causes Lifter Tick Noise And How To Fix It?

Lifter tick noise is often caused by poor maintenance, wear and tear or low oil pressure. A simple solution to fix this is to add a quart of transmission fluid to your oil. Run the engine for a few minutes and change the oil as per the recommended interval.

How Does Transmission Fluid Cling To Lifters And Clean Them?

Transmission fluid is designed to have great detergency and solvency. It clings to lifters and other engine parts, dissolving and cleaning built-up dirt and grime.

Is It Recommended To Use Atf For Cleaning Lifters?

If your engine has developed a ticking noise due to dirty and clogged lifters, then using atf is a cheap and viable solution. Although atf is not designed for this purpose, its composition makes it a great cleaning agent that won’t harm engine internals.

Adding a quart of atf to oil won’t hurt the engine, but it won’t work for every engine.

Are There Any Risks Involved In Using Atf In Engine Oil?

Although atf is best known for lubricating and cooling the transmission, its composition makes it safe to use in an engine. However, it’s essential to note that adding transmission oil to the engine adds detergents that can loosen deposits and sludge, potentially blocking oil passages.

Overusing atf can harm your engine, so do it sparingly.

How Often Do I Need To Use Transmission Fluid To Clean Lifters?

There is no set interval for using transmission fluid to clean lifters. However, it’s a cheap and efficient solution that can be done every oil change cycle. It’s a preventative maintenance measure that can help improve engine life, reduce wear and tear, and improve engine performance.

But do it sparingly and as per the manufacturer’s recommendation.


As you can see, adding transmission fluid in oil to your engine as a cleaner for lifters is a practical solution. Not only does it help remove sludge buildup, but it also lubricates the lifter components. This simple diy method is less expensive than taking your car to a mechanic, and the results can last for thousands of miles.

However, it’s critical to do your research and consult your car’s owner manual before attempting this process. Every engine and transmission is different, and some transmission fluids may not be suitable for your engine. So, follow the manufacturer’s recommendations for a safe and effective result.

By taking care of your car’s lifters, you can extend its life and save yourself a lot of hassle in the long run.
