Have you ever put transmission fluid in the oil accidentally? It may seem like a small mistake, but it can have serious consequences for your vehicle.
Putting transmission fluid with engine oil can cause damage to your engine, transmission, and other vital components. It can also lead to poor performance, reduced fuel efficiency, and even complete engine failure. This is because transmission fluid and engine oil are designed for different purposes and properties.
Transmission fluid lubricates and cool the gears in the transmission, while engine oil lubricates and cool the internal parts of the engine. These are two different types of fluid, and they should not be mixed.
It is important to understand the potential risks of Accidentally putting transmission fluid in the engine and how to identify and correct the problem if it occurs.
Whether you are a car enthusiast or just a regular driver, In this article, I will provide information about the effects of putting transmission fluid in the oil and what you can do to fix the problem if it occurs.

What Is Transmission Fluid, and What Is Engine Oil?
Transmission Fluid
Transmission fluid is a lubricant used to lubricate and cool the transmission in a vehicle. The transmission is responsible for transferring power from the engine to the wheels. It can suffer from friction and wear without proper lubrication, leading to decreased performance and efficiency and even costly repairs. Transmission fluid also helps to maintain the transmission’s internal components and keep them running smoothly.
Engine Oil
On the other hand, engine oil is a lubricant used to lubricate an engine’s moving parts, such as the pistons, bearings, and crankshaft. Engine oil also helps to cool the engine, clean it, and protect it from wear and tear. It is usually golden or amber and has a somewhat strong odor.
Difference Between Transmission Fluid and Engine Oil
The primary distinction between transmission fluid and engine oil is viscosity or thickness. Transmission fluid is generally thinner than engine oil, as it needs to flow easily through the transmission to lubricate and cool the moving parts.
On the other hand, engine oil is thicker and is designed to provide more robust lubrication for the engine’s moving parts.
Another difference is their function; transmission fluid is designed to lubricate and cool the transmission, while engine oil is designed to lubricate and cool the engine. Transmission fluid also contains special friction modifiers and other additives that help to improve the transmission’s shifting performance, while engine oil typically does not contain these additives.
Using the proper type of fluid in each application is critical since using the incorrect type of fluid can cause transmission or engine damage and lower vehicle performance. It’s also worth noting that transmission fluid should be replaced regularly, often every 30,000 to 60,000 miles. On the other hand, engine oil should be changed more often, commonly every 3,000 to 5,000 miles.
What Happens if You Put Transmission Fluid in The Engine Oil Accidentally?
Accidentally Mixing transmission fluid and engine oil can cause significant damage to a car’s engine and transmission system.
When the two fluids are mixed, it can create a sludge-like substance that can clog passages and restrict fluid flow to internal components. This can lead to increased wear and tear on these parts, causing the transmission to have difficulty shifting gears, slipping gears, and overall poor performance.
In addition, the mixture can cause damage to the transmission seals, leading to transmission oil leaks.
In the engine, the sludge-like substance can also clog oil passages and restrict the flow of oil, leading to increased friction and heat, which can cause damage to the internal components of the engine, such as bearings, cylinder walls, and pistons. In the worst-case scenario, this can result in lower engine performance, higher emissions, and engine failure.
Furthermore, accidentally putting transmission fluid and engine oil can damage the transmission control module, leading to poor shifting, slipping, or damage to the transmission. It may also damage the engine control module and cause poor engine performance.
Several warning signs or symptoms may indicate a problem with the fluids in a car’s engine and transmission system. Some of these include:
- Unusual noises, such as whining or clunking, come from the transmission or engine.
- Poor performance, such as slipping gears or difficulty shifting.
- Leakage from the transmission or engine.
- A burning odor or smoke emanating from the engine or gearbox compartment.
- Dashboard warning lights, such as the check engine or transmission warning light.
- A decrease in fuel efficiency or power.
- Overheating of the engine or transmission.
If you notice these symptoms, a mechanic must inspect your vehicle immediately to prevent further damage. It is also important to note that putting the wrong fluid in engine oil can cause damage that may not show any visible symptoms immediately but can cause long-term damage to the engine and transmission system.
What to Do Now if You Put Transmission Fluid in The Engine Oil?
If transmission fluid has been mixed with engine oil accidentally, the following steps should be taken to correct the problem:
- Drain and replace the contaminated fluids as soon as possible. This will remove the sludge-like substance created by the mixture and restore proper lubrication and cooling to the engine and transmission.
- Thoroughly inspect the engine and transmission for any damage caused by the mixture. This may include replacing worn or damaged parts, such as bearings, gears, and seals, and flushing the transmission and engine systems.
- Replace the transmission control module or engine control module if necessary.
- Check and refill fluids regularly, such as engine oil, transmission fluid, coolant, and brake fluid.
- Pay attention to any warning signs or symptoms that may indicate a problem with the fluids, such as unusual noises or poor performance, and address them as soon as possible.
- Store and handle the fluids properly, using only clean and approved containers. Avoid cross-contamination by keeping the juices in separate areas and using separate tools and equipment when working on the different systems.
Draining and replacing the contaminated fluids as soon as possible is extremely important when transmission fluid has been mixed with engine oil accidentally. The sludge-like substance created by the mixture can cause damage to internal components, clog passages and restrict fluid flow. This can lead to poor performance, leakage, and costly repairs or replacement of the transmission or engine.
Draining and replacing the contaminated fluids will remove the sludge and any other debris and restore proper lubrication and cooling to the engine and transmission. This will help to prevent further damage to the internal components and help to maintain the longevity of the engine and transmission system.
Several steps can be taken to prevent the problem of mixing transmission fluid and engine oil from happening in the future:
- Follow the product’s suggested maintenance plan and use the right fluid type for the make and model of your vehicle. Use the proper transmission fluid and engine oil for the gearbox and engine.
- Regularly check and replenish fluids such as engine oil, transmission fluid, coolant, and brake fluid. This will help ensure that the proper fluid level is maintained and that any leaks or other issues are addressed promptly.
- Pay attention to any warning signs or symptoms that may indicate a problem with the fluids, such as unusual noises or poor performance, and address them as soon as possible.
- Store and handle the fluids properly, using only clean and approved containers,d to avoid cross-contamination by keeping the fluids in separate areas and using separate tools and equipment when working on the different systems.
- Educate yourself about the fluid type and the correct fluid level your car needs. This will assist you in determining whether something is wrong with the fluids and addressing the problem as soon as possible.
- Have your automobile serviced by a qualified and trustworthy technician. This will ensure that the correct fluids are used and that the maintenance schedule is followed.
- Always double-check the fluid type before pouring it into the reservoir to avoid accidentally adding the wrong fluid.
By following these steps, you can prevent the problem of mixing transmission fluid and engine oil from happening in the future and maintain the longevity of your car’s engine and transmission system.
