Yes there is. They both will have different additives in them. There viscosity (thickness) will also be different. Transmission fluid has a red dye that is added so it can be distinguished from engine oil.
no
none
Automotive oil is formulated as a engine crankcase oil and Motorcycle oil is formulated three jobs a crankcase oil, a transmission-gear oil, and a wet clutch oil.
Crankcase or motor oil is thicker than transmission oil. That's one difference, there may be more (other than color)
There is NO "Reservoir" for a AX4N, Automatic Transmission. There is an oil pan and a torque converter which is between the engine and the transmission where it bolts to the engine.
Between the engine oil pan and the transmission oil pan. It is cast aluminum.
it's lubricating properties
engine oil is thick than hydraulic oil
You should drain the oil in the engine. Put engine oil back in the engine because the transmission oil is not made for engines and will hurt the moving parts of the engine if left in.
engine oil pan is on bottom of engine transmission oil pan is on bottom of transmission
5w30 for engine oil. Dexron 3 for transmission fluid on an automatic.
If you mean "engine oil" then I would think that a seal has failed between the transmission unit and the "engine" Other than that maybe someone put or topped up the transmission fluid in the wrong location. Change of oil is required any way
