is gear oil the same as transmission fluid


What is Gear Oil?

Gear oil is a viscous liquid lubricant made specifically for manual transmissions and / or differentials in automobiles. Gear oil is designed to lubricate gears, bearings, shafts and other components of an automobile transmission/differential system. Its purpose is to reduce friction and wear between the parts of the transmission and differential.

What is Transmission Fluid?

Transmission fluid is a complex combination of special lubricants and additives. It is used in automatic transmissions and continuously variable transmissions to lubricate, cool and protect the moving parts of the transmission. It is highly engineered and provides superior lubrication, rust and corrosion protection, smoother shifting and better fuel economy.

Is Gear Oil the Same as Transmission Fluid?

The simple answer is no, gear oil and transmission fluid are not the same thing. They are designed for different applications and are not interchangeable.

Differences Between Gear Oil and Transmission Fluid

  • Visosity: Gear oil is generally more viscous (thicker) than transmission fluid.
  • Additives: Gear oil has fewer additives than transmission fluid.
  • Price: Gear oil tends to be more expensive than transmission fluid.

In conclusion, gear oil and transmission fluid are not the same and they should not be used interchangeably. Each one has a specific application and is designed for that purpose.
