Oliver 4-78-15LL transmission identification/fluid type

[Dannyboy1986]

I am looking at what i believe to be an Oliver/White 4-78-15LL backhoe. Trying to figure out what transmission it has and the fluid type. Has two pedals side by side on the right with F on one and R on the other. No hand throttle. I believe it is a revotorc funk shuttle shift?

Ran one of them in the 80's for a local trucking co. The throttle is part of the direction pedals. White called it a Reverse-O-Torq, not sure who made it. I do think it ran dexron ATF in it. That machine loaded thousands of tons of aglime and gravel and is still in use today. Steve.

I got the fluid topped off. Checked the dipstick and it is still at the bottom. Looks like the transmission is two sections? How does the front section get fluid? You can't really get a funnel to the front section where the dipstick is?
