Choosing the best transmission fluid : Things to Consider
Which Transmission fluid should I go for? Should I go for the aftermarket ones or the OEM ones? What about Autozone transmission fluid? Now that you know all the best options that are available to you, the next crucial thing would be to choose the transmission fluid that will serve you the best while meeting all of your needs. But taking the decision part is not often the easiest as you have to keep in mind about things like your budget, vehicle compatibility those sorts of stuffs. It turns out, the best transmission fluid that your friend got the best results from is not doing you any right, and it's not a rare phenomenon at all. Often, the best for someone else is not even good for you. It kind of varies from one condition to another. Before changing transmission fluid or refill you should check transmission fluid level.
However, you don't have to be confused about that as we are here to help. Here we have added the crucial things that you can consider to choose the best transmission fluid for your vehicle:
1. Vehicle Compatibility
Would you put water into your combustion engine’s fuel tank? No, right? But why? – Because it’s not compatible unless your engine actually run on water (that’d be revolutionary). The same principle applies to Transmission fluids. Choosing the wrong transmission fluid that is not compatible with your vehicle may cause fatal transmission failures.
Therefore, it is a significant parameter to consider when looking for a transmission fluid. Some transmission fluids have universal compatibility, which means that you can apply it for a wide range of automobiles. This is even more crucial if you have more than one vehicle where choosing different fluids for different vehicles is often an ordeal task. Hence, having multiple vehicles, a transmission fluid that supports all your vehicles may just be the best one for you.
However, you should always double-check while choosing a transmission fluid that claims to support all of your vehicles. Go through the manufacture's instruction manual to find out if the transmission system of each of your cars supports that specific type of transmission fluid. If you don't have it for reasons, you can still search online and have a look at your car manufacturer's website. It's crucial to know what transmission fluid to apply that will boost your car's transmission system to bring out the best performance out of your vehicle's transmission. A poorly compatible transmission fluid will only worsen the overall efficiency of your beloved vehicle. Hence, it's wise to take caution.
2. Protective additives
Oxidation, foaming and corrosion are three arch-enemies of any transmission system. They make the transmission shifting go harsh eventually damaging the parts that lead to fatal transmission failures. Hence choosing a transmission fluid with protective additives is a must.
The best transmission fluids come with anti-oxidation formula that works on the oxidation stability. Some also include additives that can reduce foaming, protect against corrosion, prevent transmission noise and many more.
It often happens that a specific transmission fluid remains in your car's transmission starts to break down after serving for a long time. It may change the fluid’s lubrication properties like viscosity which may in term harm your transmission system leading to transmission failures.
To prevent this anomaly, you should go for one with the best transmission additive that prevents fluid break down and stays in the system for a longer time. This will also save a lot of your bucks as you don't have to change the transmission fluid frequently
3. Type of Transmission Oil : Conventional vs Synthetic
If you have gone through our best reviews, you may have noticed that two specific types of transmission fluids are the conventional ones and the synthetic ones.
Synthetic ones are of the latest technology and perform far better than the conventional ones. They tend to withstand a much higher temperature making them suitable for delivering unvarying performance even in the extreme conditions. They don’t break down easily and stays in the system for a longer time. But with perks like these, they are also quite expensive.
On the other hand, the conventional ones just do the work. They are cheaper, have a lower heat tolerance and breaks down quickly. But if your vehicle is of an older model, it's better to use the conventional ones as synthetic ones may not be compatible with older vehicles.
In a word, if you have the money and a car that is not an older model, you should definitely go for a synthetic transmission fluid.
4. Brand
The brand of the transmission fluid is another vital factor to consider while looking for new fluids. The renowned brand tends to manufacture better transmission fluids than regular fluids that are available in the market. Especially, if you're into OEM fluids, a renowned brand should be your priority.
However, many lesser-known and aftermarket brands are now in the market with premium quality transmission fluids. These fluids are not only effective but also cheaper, which makes them a bang for the buck. So, you can certainly try these products if you are open to aftermarket products.
However, no matter which transmission fluid you chose, please go through the product specifications of these brands and make sure that they are compatible with your vehicle’s transmission system.
5. Price vs. Your Budget
Not every transmission fluid cost may fall under your budget. But that doesn’t mean that the ones that are under the cheap margin are worthless. In fact, there are a lot of economical options that can provide superior quality.
Hence, if you find yourself to be pressed under a limited budget, you have found the best one that comes under that margin, and there are a lot of options too. If you're in an urgent need for a transmission fluid, then don't wait as you may be damaging your system. Make the best use of what you got.
6. Your Location
While choosing a transmission fluid online, you may often find out that the distributors don't ship it to your location. And again, you may not find it in the local store. If that's the case for you, then you have to choose the best one that is available in your location online or offline, especially if you like to buy your things handpicked from the local stores.
Again, the geographical condition of your location or region is another crucial parameter as not all the transmission fluids may work well under your environment. Many fluids break down in excessive heat, some malfunction in cold weathers. So, if you live in such a situation, then choose a fluid that has an all-weather optimum performance as otherwise, it may not just work for you and further worsen your transmission system.
After all of these parameters well-considered, choose the transmission fluid that satisfies all of the considerations above. Bear in mind that, the sense of one fluid being the best one universally is not quite the scenario, and there are always facts to consider. To bring out the best from your transmission fluid, you have to make sure that it can perform in its optimum conditions. The best bike never even runs on water – the same simple analogy is accurate when it comes to choosing the best transmission fluid for your automobile.
Conclusion
Transmission fluid is no less critical than the combustion fuel for your vehicle. The transmission system is what allows your vehicle to run so smoothly, and a simple transmission failure can even lead to fatal accidents. Hence, keeping your vehicle's transmission system smooth and running should always be a top priority.
Transmission oil or fluids doesn't only help to keep your transmission system buttery smooth, but it also improves the overall efficiency of your automobile. So, upgrading to the best transmission fluid is a must.
