I NEED SOME HELP!

Does anyone know the shift pattern for this one? it's a 5 speed.

Also what type of lube does it take?

 

I'm betting on it taking plain ol 80w 90 gear oil.

For a shift pattern I'm not really sure, but in our 1985 600 370 cu dumptruck its got a way left up 1, left up 2, left down 3, right up 4, right down 5, way right up reverse. I'm not sure what kinda tranny is in it tho
