Best Synthetic Transmission Fluid 2020

Transmission fluid is to the transmission what oil is to the engine. This transmission fluid facilitates smooth operation of the gears in both manual and automatic transmission vehicles. It lubricates the moving parts and keeps things clean and cool inside the gear box, much like the engine oil. However, this does not mean that the two are interchangeable.

In the early days, engine oil was used as a lubricant for the automatic transmissions as well. But as the systems became more sophisticated, it called for specialized lubricants. Specific transmission fluids were then formulated to meet these complex requirements.

Today, there is a broad range of automatic transmission fluids (ATFs) with varying specifications to suit the demands of different types of transmission systems. Specs like Dexron, Mercon, ATF+ and Type 4 differ in the combination of performance-enhancing additives, friction modifiers and other ingredients that are specially designed to suit specific vehicles. It is best to follow the manufacturer’s recommendations specified in the owner’s manual.

 All other things being equal, a synthetic transmission fluid is considered better than natural petroleum based ones. The former has a superior engineering which allows for better resistance to oxidation and thermal degradation, sustained viscosity, smoother shifting, better vehicle performance and extended transmission life. It also lasts longer thus allowing for fewer changes resulting in savings of both money and time.

However, keep in mind that no oil can be engineered to last forever. Therefore, ‘sealed for life’ transmissions are just a myth. It is better to check the transmission fluid regularly using the dipstick or get it checked at every oil change. The change interval is usually 30,000 to 60,000 miles for a manual and every 60,000 to 100,000 miles for an automatic vehicle.

When it comes to which tranny fluid to choose, there are many other aftermarket brands apart from the manufacturer-specified ones. These also feature a specific compatibility with particular makes and models, but the range is broader.

For instance, Royal Purple offers high-quality transmission fluids that also feature on varied lists of best synthetic transmission fluid for 2020 on account of their high film strength, lower co-efficient of friction and superior oxidation stability. These premium lubricants outperform other regular brands in terms of lower operating temperatures, greater wear protection, reduced friction, greater power, improved fuel economy and extended transmission life.

Royal Purple’s Synchromax is recommended for manual transmissions that specify an automatic transmission fluid, 2-cycle motorcycle gear boxes or other transfer cases requiring a light-viscosity lubricant. It can be used as a replacement for VersaTrak, Auto-Trak II, and Synchromesh. On the other hand, Max ATF is a high-performance lubricant that is renowned for its ability to cope with varied power outputs including the demands of high-performance engines. It can be used in a different cars and trucks that specify ATF fluids like Allison C-4, BMW LA2634, GM DEXRON, Hyundai SP-II, Nissan Matic-K, Subaru ATF, Toyota T-III, VW G, Suzuki 3317, Mazda ATF MV and many more.
