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.
Transmission fluid runs between all the gears in your manual transmission and running metal-laden fluid through metal gears can end up causing untimely wear. Another thing to look out for is a transmission fluid leak. While the transmission fluid in manual transmission vehicles doesn't tend to naturally break down on its own, loose parts or impact from road debris can cause leaks and low fluid levels.
