Is gear oil same as transmission fluid?
Transmission fluid, also called gear oil, ensures smooth functioning and extended life of transmissions, transfer cases and differentials in cars, trucks and other machinery. Like motor oil, they are composed of base oil (mineral, semi- or fully synthetic) and additives.
What are the types of gear fluid?
After selecting the viscosity grade, the basic type of lubricant must be chosen. While there are many variations, gear lubricants can generally be placed into three categories: R & O, antiscuff and compounded. The gear lubricant type that best fits a given application will be determined by the operating conditions.
Which is the best oil for manual transmission?
Selecting the right gear oil or transmission fluid is critical to the life and performance of your manual transmission. (Image/Tremec) Similar to what we discussed in our Automatic Transmission Fluid 101 post, selecting the right gear oil for your manual transmission isn’t as easy as it might seem.
What’s the difference between engine oil and gear oil?
In fact, many modern manual transmissions actually spec for automatic transmission fluid instead of a traditional gear oil. Regardless of what your manual transmission uses, the fluid or oil’s primary function is lubrication—preventing metal-to-metal contact between the meshing gears. Gear oil is different from engine oil.
What kind of lubricant is used in a transmission?
Gear oil is a lubricant made specifically for transmissions, transfer cases, and differentials in automobiles, trucks, and other machinery. It is of a high viscosity and usually contains organosulfur compounds. Some modern automatic transaxles (integrated transmission and differential) do not use a heavy oil at all but lubricate with …
Is the gear oil the same in a transaxle?
Though the role of the gear oil is the same, there are extra factors at play in a transaxle. That’s because transaxles function as both an axle and transmission. You can read more about transaxles and how they differ from transmissions here.

When to change gear oil in a car?
Keep in mind that most modern manual transmissions have gear oil service intervals well north of 50,000 miles, with many being “lifetime” oils. Driving enthusiasts, however, change gear oil to deliver improved transmission performance—like smoother shifting or added durability in extreme conditions.
