Whats the difference between transmission oil and automatic transmission fluid?

A manual Transmission will use Gear oil or transmission fluid. and an automatic transmission will use Automatic transmission fluid. Gear oil is a very thick type of oil (engine oil is 30 weight and gear oil is 80 weight) that is thrown around inside the transmission when the gears are turning. Automatic transmission fluid is a Hydraulic fluid that is designed to be pumped and it operates several clutches band brakes inside the transmission. These fluids both provide cooling and lubrication to the transmission but are not interchangeable since they are very different in Viscosity and would harm the transmission if they are switchedWhats the difference between transmission oil and automatic transmission fluid?
Really it's only how you like to say it.


Most folks will tell you that ';fluid'; is what is used in an ';automatic'; transmission, and ';oil, or gear grease'; is what is used in a ';manual or standard'; transmission.Whats the difference between transmission oil and automatic transmission fluid?
These days they can be one in the same. Go by the detailed information in your specification pages in your manual. Tractor hydraulic (thin low viscosity) fluid is used in farm tractors to run the transmissions, hydraulic systems and the rear end final drives and planetary gears. Hows that for one type of oil. The diesel motors of coarse have entirely different oils for the crankcases. As you know in today's front wheel drive cars automatic transmission fluid circulates through the transmission and the differential ring and pinion. The same light fluid is used in standard transmissions to make them shift easier in cold climates and provide superior lubrication in hot weather.
no different,unless 1 of them is a manuel transmission,then it could take gear oil.
