When we look at the functions of the transmission system, the transmission fluid is a key component of the system’s operation and overall performance. It’s responsible for lubricating mechanical parts, maintaining fluid pressure, cooling, preventing oxidation, conditioning the gasket, and preventing rust.
What is the purpose of transmission oil?
In an automatic transmission, it not only lubricates the moving parts, but also provides hydraulic pressure and friction to make the internal parts work. Transmission fluid in both manual and automatic transmissions also helps to keep the transmission cool.
How does transmission oil work?
The transmission fluid is pressurized by an oil pump, which allows the speed to change depending on the vehicle’s speed, tire revolutions per minute, and other factors. The gear pump is placed between the planetary gearset and torque converter, where it pulls and pressurizers transmission fluid from a sump.
What happens if you don’t replace transmission oil?
Changing your transmission fluid periodically will increase the lifespan of your transmission. On the other hand, if you never change it, you will have dirty and grimy fluid that will fail to lubricate and disperse heat very well.
Is transmission oil necessary?
Yes, even a manual needs transmission fluid. The type of fluid can vary from car to car, however. Some manuals require conventional engine oil, and others function best with automatic transmission fluid.
What happens if transmission fluid is low?
When your transmission fluid is low, your car won’t generate as much hydraulic pressure, leading to what’s known as gear slippage. Gear slippage commonly manifests as a failure to accelerate properly. When your transmission fluid is low, you may notice your vehicle reaching high RPMs while moving sluggishly.
How do I know if my transmission fluid is low?
Signs of Low Transmission Fluid
- Noises. If your transmission is working properly, you shouldn’t hear any noise while you’re driving as it should transition smoothly. …
- Burning Smell. Any foul smell coming from your car should direct you to your nearest service center. …
- Transmission Leaks. …
- Slipping Gears.
What causes low transmission fluid?
If your transmission takes a while to go into gear, you may have a low transmission fluid condition because of a leak or contamination due to lack of maintenance or even water intrusion during off road or flooding conditions.
What’s the difference between transmission fluid and oil?
A couple of differences are the following: Motor oil is designed to deal with the products of combustion, whereas automatic transmission fluid (ATF) does not see contaminants from fuel burning. … Transmission fluid is also used by your steering system to keep its parts moving smoothly.
How can you tell the difference between transmission fluid and oil?
The easiest way for you to tell the difference between transmission fluid and engine oil is the colour. Engine oil is typically an amber colour while transmission fluid is normally red.
How do you know when to change your transmission fluid?
Signs That You Need to Change Your Transmission Fluid
- Puddles under your car. …
- Roaring sounds when you accelerate or go around corners. …
- Difficulty shifting. …
- Engine revving when going around corners.
- A chattering noise when you start driving. …
- A slight burning smell.

Does changing transmission fluid improve performance?
Changing your transmission fluid regularly, especially when it has turned black, is a great way to improve your fuel economy. Your transmission will run smoother after you change the fluid, which means your engine will run smoother as well. One of the worst things that can happen is engine lock-up.
How long does a transmission fluid change take?
Mostly, the average time it takes to change the fluid in a transmission it 1 hour. However, because some of the newer vehicles are built differently, they don’t require a fluid change as often as older models, so be sure to read the owner’s manual or ask your mechanic for professional advice about transmission service.
What happens if you put transmission fluid in the oil?
In most cases, adding ATF to motor oil reduces cleaning power. Instead, ATFs have elevated levels of friction modifiers and other additives that help protect gears and clutches. Second, ATF can disrupt the engine oil formulation and reduce its effectiveness.
How long does a transmission last?
Without service and maintenance, some transmissions can fail in as little as 100,000 miles. If you drive around 10-15,000 miles a year, your transmission could be down for the count in seven years! With care and service, transmissions can last 300,000 miles or more.
Can I change my transmission fluid?
You should change your automatic transmission fluid according to the manufacturer’s recommendation— whether that’s 30,000 or 100,000 miles. … But here’s a new way to change your fluid without going under the car and without spilling a drop. The procedure takes less than 30 minutes.
