what r u looking at in the window tranny oil,motor oil, rev. oil

 

I believe you are looking at Engine oil in the glass. If it is a wet clutch system then it is lubricated by the engine oil. The only time it will have seperate tranny oil is if it were shaft drive. The shaft drive has its own gearbox, gear oil and the reverse gearbox has its own gear oil with dipstick. I could be wrong but that is how most of these are like.

 

On a Falcon 250, you are looking at gear lube in the reverse gear box, the engine oil has a dip stick on the Falcon 250 & the gearbox has a window, so in the window is gear oil 80/90w.
