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.

How Gear Oil Works?

The transmission, transfer cases, differentials and gear boxes in cars and trucks contain a series of gears and bearings. These keep moving and come into contact with each other while converting the torque into power and transferring it to through the drive shaft to the axles. The gears intertwine every time the clutch engages and disengages as the vehicle changes acceleration.

In short, there is a lot of rolling, sliding, grinding and other violent action going on in the shafts and gears. This is bound to generate a lot of heat and friction which will cause untold wear and tear on the teeth and other metal surfaces until they finally destroy each other.

Lubrication is essential to both promote easy movement and control the increase in temperature. And this is where gear oil enters the picture.

As the name goes, gear oil is specifically designed to protect the gear sets and keep them working cohesively and efficiently. It has a higher viscosity than regular engine oil which allows it to stick to the moving parts and keep them lubricated properly. The oil forms a film on the various metal surfaces and keeps them apart while they work together to deliver optimum power output and keep the vehicle running smoothly. For certain applications, the gear oil is fortified with extreme pressure (EP) and anti-wear additives to deliver increased protection.

Gear oils do not come into contact with the gases, acids and other pollutants like engine oil. Therefore, they can last much longer and have an extended change interval. However, the gear oil is also bound to get contaminated with moisture and debris which can discolor the oil or make it more viscous. As the gear oil breaks down, the increased friction can cause difficulty in engaging gears and damage the components as well. Left unchecked, it can entail a costly overhaul.

Therefore, regular checks and changing the gear oil based on the manufacturer’s recommendation is crucial.

There are a variety of gear oils in the market and in general, synthetic gear oils deliver greater resistance to shear breakdown than mineral oils. Gear oils are further classified by the American Petroleum Institute using GL ratings ranging from GL1 to GL5. The higher the oil’s GL rating the greater pressure it can sustain and vice versa. Most modern gearboxes use a GL-4 oil while separate differentials require a GL-5 oil as it contains more EP additives that lower the coefficient of friction.

 

Royal Purple Gear Oil, Max Gear is carefully engineered for use in truck, motor home/RV, and automotive front or rear differentials, manual transmissions and lower gear units of marine engines that specify use of an API GL-5 or GL-4 fluid. The high quality synthetic oil is further fortified with Royal Purple's proprietary Synslide additive technology that makes it outperform other GL-5 synthetic oils in terms of lower friction, decreased operating temperature, excellent corrosion protection, maximum horsepower, suppressed oil-water emulsion and prolonged gear and bearing life.
