How to Choose the Proper Automatic Transmission Fluid
Choosing the right automatic transmission fluid (ATF) can be a difficult task. It's not always evident whether or not an ATF is suitable for your vehicle. Getting the appropriate one is important since using the wrong one might harm the transmission. As a result, some background knowledge may be beneficial.
Automatic transmission fluids contain specific friction coefficients, viscosities, and additives. ATFs are designed to operate with certain automatic transmission designs. They aren't all created equal. Furthermore, using a fluid that is not recommended by the vehicle manufacturer will void the transmission warranty if your vehicle is still under warranty.
How are ATFs produced?
Automobile manufacturers create automatic transmission fluids, or at the very least set standards for them. However, automobile manufacturers do not produce ATF. Petroleum firms are in charge of this. They make ATF using a formula of basic oils and additives devised by the vehicle manufacturer and licensed to the oil company. The oil company can also utilize the automaker's unique ATF brand name as part of the licensing fee. Dexron, Mercon, and ATF+4 are the most prevalent names, which are brand names for GM, Ford, and Chrysler fluids, respectively.
However, whenever a new ATF is launched, automakers normally stop licensing existing ATF formulas. In recent years, all of the major automakers have produced entirely synthetic ATFs, which have mostly replaced traditionally based ATFs. The new ATF can be used in vehicles that were initially provided with the previous ATF formulation. Alternatively, the old ATF can be replaced with a fluid that an oil company says fulfils the original car manufacturer's specifications for the old formula ATF.
Oil companies, on the other hand, aim to simplify the old formula ATFs. Rather than using the automobile manufacturer's exact formula, petroleum companies attempt to create a single fluid that fulfils the original criteria of multiple distinct manufacturers. These are ATFs that may be used in a variety of vehicles. A fluid that claims to fulfil both Dexron-IlI ATF and Mercon V requirements is an example.
Choosing the Right Automatic Transmission Fluid
Consult the owner's handbook for a good place to start. It will indicate if Dextron or Mercon transmission fluid is required. It's critical to read and follow the owner's instructions. Some imports, for example, will not take Mercon and will instead demand brand-specific fluid.
When it came to automatic transmission fluid, there were just two options: Type F or Dexron. There are several solutions available nowadays. This is because automakers are attempting to improve their vehicles' fuel efficiency by developing lubricants to fulfil a variety of needs. That's why you need to be cautious about the fluid you use, since the improper one might cause your engine to fail in a variety of ways.
When selecting a lubricant for your performance vehicle, bear the following in mind:
If you own a classic automobile, be sure the fluid you choose is compatible with it. You must be extremely cautious while using newer fluids because they were not designed with your vehicle in mind. The GM 4L60E, for example, is believed to operate well with Dexron VI. However, because that fluid wasn't invented until 2005, you'd be better off sticking with Dexron-IlI ATF.
Fluid Types, Brands
You might assume that if you drive a Ford automobile, you can only use Ford fluids in it. In reality, this isn't the case. You could be better off using a different kind of fluid altogether in some circumstances. Because the brand isn't 'right,' don't be blinded to the best options.
Avoid Universal Fluids
To clear up any ambiguity, several businesses are developing universal automatic transmission fluids that may be used in any vehicle. However, if you're driving a high-performance vehicle, you should avoid them. Stick to a single-purpose fluid you're confident will function in your vehicle.
Synthetic Fluid vs. Conventional Fluid
Car owners must also decide whether to use synthetic or traditional transmission fluid. Synthetic fluid is more expensive, but it performs better and lasts longer at greater temperatures. On some older versions of automobiles, though, it's really preferable to use traditional fluid - especially if synthetic has never been introduced. Making the swap may cause more harm than good, resulting in costly transmission repairs.
Choose Doxa Dexron-IlI ATF & Full Synthetic Transdex ATF
Doxa Dexron-IlI ATF is basically multipurpose, high-performance fluid. It has been designed to meet the criteria of Ford Mercon, General Motors Dexron-III, and Allison C-3 or C-4. It has high friction resistance and oxidation stability, allowing for constant and smooth power transfer. On the other hand, Doxa Full Synthetic Transdex ATF is highly suggested for all vehicles that require Mercon/Dexron III or Allison TES 468 and TES 295 ATFs, including garbage trucks and buses. Because of its excellent thermal and oxidative stability, the viscosity remains nearly constant, preventing deposits and oil thickening, extending transmission life and preventing improper gear changes. Under all situations, excellent transmission cleanliness allows for longer oil drain and less maintenance. It offers excellent temperature reduction due to reduced friction results in longer oil and component life, as well as longer drain times and less maintenance.
