Gear oil is very thick and can handle very high heat before it burns off and needs to be replaced. Automatic transmission fluid does get hot, and boils to the point that it expands and leaks out. Transmission fluid is a slippery liquid that acts as a lubricant for all of the moving parts inside the transmission.
Is transmission fluid and gear oil the same?
The simplest answer to the difference between transmission fluid and gear oil is in the purpose for which they are designed. Transmission fluid is engineered to work with automatic transmissions, whereas gear oil is typically intended to work with manual-type gear boxes.
Can you mix ATF and gear oil?
While technically they will mix, they are very different and should not be mixed. ATF is thinner than most gear oils, so you will reduce that protection.
