Simon, im no expert , but since no one has responded, i will.... On the larger tractors the transmission OIL PUMP runs off the torque converter / back end of the motor. I dont know about the smaller FIAT machine.. Do you have a trans oil pump that runs off the accessory drive ( motor) that could have blown an oil seal on the shaft ??

Thats the only way i see trans oil getting to the motor.

I think it has something to do with a breather tube (it that's what it looks like) cuz it goes from the top of the front of the tranny there is a nipple and the other end goes on a nipple on the back of the torque converter. There's no clamps on it so I don't think has pressure, but I kept having trans oil leak out, but idk why cuz it wasn't overfilled. So. I put clamps on it and left the dipstick out, just in case it needs to breath. But the fluid still was disappearing so that's when I checked the engine oil cuz there was no where else it could have went, and that's when I noticed it was way full. And as for the trans pump, we just had one put on but I'm not sure what it drives of

*off of. But the pressure seems fine (until it runs out of oil in like an hour and half of course)

Try posting this on the https://www.allischalmers.com/forum/construction-and-other-equipment_forum3.html" rel="nofollow - Construction and other equipment Forum here. Someone who doesn't check this Farm Equipment Forum might see it on that forum, and have an idea. Your machine is a Fiat Allis 10C isn't it?
