What Is The Difference Between Gear Oil And Transmission Fluids?

There is a gear system in each and every automobile that needs to be shifted properly in order to keep the automobile moving smoothly. There are various models of car available in the market some cars have gear sticks that need to be operated manually, whereas the other variety has an automatic system that depends on the force and speed of the car. Regular oiling is important for both the models that enhance lubrication and helps them keeping cool and clean.

Gear Oil

The gear oil is majorly used by the standard transmission systems, differentials in lorries, automobiles and various other machines, and transfer cases. It is basically thick consistency oil that can endure excessive heat before burning off and requiring any replacements. This property facilitates in protecting the gears. The higher viscosity enables the lubricant to move all over the gear system.

Gear oil key facts:

  • The gear oil is mainly used in a manual transmission system that facilitates lubricating and preventing decompositions in a manual system
  • Gear oil is thicker in consistency as compared to transmission fluid because gear oil is basically designed for lubricating the gearbox differentials and transfer cases.
  • The manual gear system produces excessive friction due to the pressing and releasing of clutch and gear changes. The gear oil has elements of sulphur bearing anti-wear components. This helps in increasing the life of the gears.

Transmission Fluid

The transmission fluid is required for the Automatic systems. The transmission fluids are a kind of detergent oil that has a very slippery texture. It helps in lubricating and removing remains from all the movable parts of the transmission system. It is generally thinner in texture and free-flowing as compared to gear oil. The transmission fluid also works as a coolant and such a liquid that enables transmission of power to the transmission system from the engine. The transmission fluid generally suits the automatic transmission system whereas the manual transmission system requires multiple types of oil such as heavyweight gear oil, regular vehicle oil and transmission oil as well in few circumstances. Therefore it is recommended to follow the car manual to find out the suitable transmission fluid for a better life of the vehicle.

Transmission Fluid key facts:

  • Transmission fluid has a thinner consistency as compared to gear oil and is generally green or red in colour.
  • Transmission Fluid acts as a hydraulic liquid designed for the four-wheel drive and the automotive steering system in automatic cars.
  • The transmission system runs effortlessly and nominal wear and tear due to lubricating and detergent-like properties of the transmission fluid.
  • Transmission Fluid include a whole lot of additional supportive elements that includes elements to protect from oxidation and rust, viscosity index enhancers, kinematic viscosity, anti-foam elements, cold-flow compounds, gasket compounds, petroleum dyes, anti-wear elements, surfactants and dispersants that help cleaning and shielding spare parts of a transmission system, seal swell elements that increase temperature range and speed, and high temperature thickeners.

The most important fact is that there are major differences between the manual gear and automatic gear systems. Therefore the related oils are invented appropriately, in order to fulfil the different requirements. Henceforth recognizing the differences between gear oil and transmission oil can help increase the life of the vehicle.
