Each car has its own recommendations from the manufacturer on which transmission fluid your car needs. Some transmission fluids are very incompatible with different transmission types as they use different additives in the fluids.
Is all automatic transmission fluid the same?
Automatic transmission fluids have specific viscosities, friction coefficients, and additives. ATFs are engineered to work with the design of specific automatic transmissions. They are not all the same.
Does it matter what automatic transmission fluid you use?
Even if you change your transmission fluid, you never will be able to drain all of the fluid from your system so it is important to use the same kind of fluid. It is also important to use the correct type of automatic transmission fluid because different fluids have very different properties.
What happens if you use the wrong automatic transmission fluid?
Automatic transmissions must only use the fluid specified by the automaker, such as General Motors’ Dexron series or Toyota’s Type T. Using the wrong fluid can cause poor lubrication, overheating, and possibly transmission failure. A mechanic might not be able to reverse the damage, even by flushing the transmission.
Are all transmission fluids compatible?
Synthetic ATF and conventional fluids are 100 percent compatible with each other.
What can be used in place of transmission fluid?
Any light weight quality engine oil or hydraulic fluid will work 5 to 10 single weight or multi weigh 5W-30, 10w 30. Yes.
Can you mix old and new transmission fluid?
This fluid starts to lose its standard properties and should be changed to keep the transmission parts and its performance at its peak. Mixing old and news fluids wont give you the ideal viscosity and the reduces the performance of the transmission system.
What is the difference between ATF and ATF 4?
ATF +4 is a synthetic fluid for finely-tuned transmissions, so if you use a non-synthetic ATF instead of ATF +4 in a car or truck that calls for it, you could damage the transmission. You may use ATF +4 in most applications that call for older Dexron and Mercon fluids.
Is Synthetic Automatic Transmission Fluid better?
Synthetic transmission fluid is made to last longer than conventional types, so you can go longer between fluid changes without sacrificing quality lubrication. However, synthetic oil costs more, so we recommend you do the math to see which type of transmission fluid will cost you less over the life of your vehicle.
What are the symptoms of low transmission fluid?
Symptoms of Low Transmission Fluid
- Drips or puddles underneath the car.
- Difficulty shifting through gears and/or slipping.
- Shuddering or shaking.
- Lurching or sudden jerks.
- Transmission won’t engage.
- Humming or clunking noises.
- A burning smell.
How do I know what kind of transmission fluid I need?
The easiest way to make sure you’re using the right type of ATF is to check the owner’s manual. It’ll tell you exactly which ATF the manufacturer recommended for your car. You may also find a recommendation on the dipstick. Either is a reasonable resource for determining the right type of fluid for your transmission.
Will transmission fluid hurt your engine?
The transmission fluid will not be providing exactly what the engine needs in order to be properly lubricated and you could be causing your engine damage by continuing to run it with the tranny fluid in there. As you’ve suggested, there is a real chance of blowing out seals due to having too much fluid in the engine.
