Frequent question: Are all transmission fluids the same?

Always check your owner’s manual for the type of fluid recommended for your vehicle by the manufacturer. Most, but not all, transmission fluids are blended with synthetic base oils to offer better performance, with improved resistance to heat, cold, oxidation, friction, and shearing.

Does it matter what kind of 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.

Is it OK to mix transmission fluids?

Yes. Synthetic ATF and conventional fluids are 100 percent compatible with each other.

What are the different types of transmission fluid?

In general, there are two main types of transmission fluid: automatic transmission fluid and manual transmission fluid. There is also synthetic transmission fluid and specialty fluids used and specified in various types of transmissions including CVT and dual clutch models.

What happens if you use the wrong transmission fluid?

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. Mistakenly adding motor oil or brake fluid can also destroy your transmission.

Which transmission fluid is best?

Our top pick for the best transmission fluid is the Castrol Transmax Dex/Merc ATF. It works for the majority of domestic cars out there and delivers great results. If you’re looking for something even more wallet-friendly, check out the ACDelco Dexron VI Synthetic ATF.

What’s the difference between CVT and ATF?

Firstly, we need to know what is ATF and CVT transmission system. ATF stand for (Automatic Transmission Fluid). … CVT system doesn’t have set of gears to drive the vehicle. The CVT can change seamlessly through a continuous range of the effective gear rations.

Does transmission fluid have a shelf life?

Currently, according to known oil specialists and lubrication laboratory testing a non-used or non-opened lubricant, engine oil, ATF, coolant, antifreeze, transmission fluid, grease, gear oil, transfer case fluid or brake fluid product has no expiration date.

What happens if you mix different types of transmission fluid?

The most common situation where the wrong transmission fluid is used is in the case of using automatic transmission fluid in place of variable transmission fluid and vice versa. Adding ATF to a to a CVT will eventually result in the death of your transmission.

How much does it cost to get a transmission flush?

A typical transmission flush will cost around $150. A transmission flush on smaller cars may cost in the low $100s while it may cost more than $200 on larger vehicles. A good rule of thumb is that a flush costs about twice as much as a fluid change.

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.

What happens if you overfill transmission?

If you add too much transmission fluid, you will notice that it may foam, and that can bring about erratic gear shifting. Some other problems that may arise include oil starvation and transmission damage. … Adding too much transmission fluid can also cause early failure and damage of parts as result of excess pressure.

Can you use motor oil instead of transmission fluid?

Manual transmissions can accept a variety of fluids: regular motor oil, automatic transmission fluid or heavyweight hypoid gear oil.

Is synthetic transmission fluid better than regular transmission fluid?

A synthetic fluid has the capability of providing your transmission with a smoother operation. Because of superior engineering, the synthetic fluid is better at lubricating your transmission and is able to sustain its viscosity in a broad temperature range. … This will likely be true even with variations in temperatures.
