Farmall 300 Transmission Fluid Change?

I posted a picture to help out with where I am talking about. I drained some nasty grease from all three drain plugs on the bottom of the tranny. All told I got about 7 gallons or so out. I then removed the fill plate on the top of the tranny by the gear shift and added until it ran out of the check hole. (Red Arrow) The problem is nothing came out of the (yellow arrow) check hole by the clutch rod. I noticed a drain? hole (white arrow) that seems to be in the same area the the small plate in from of the belt drive is in. The question is how do I fill the front of the tranny? (yellow) because when I added a bit of fluid past the TA plates it went right out the (white arrow). Do I fill it using the check hole? Please help, I"m terribly confused.

Just put the red arrow plug back in a add another half gall to gallon and wait a while it will run slowly up to the front check yellow arrow. Then double check both plugs after a bit. As for the other hole underneth, that is a drip hole for leakage past ta seals to escape. Should be using Hy-tran or equivilent.
 
Please allow me to reiterate what pete 23 just told you; do not use typical gear lube in an early T/A tractor like yours. They take the much lighter Hy-Tran type hydraulic fluid in the rear-end. Forgive me if you already were aware of this, as I do not mean to offend.

So the fact that the white hole is lower than the yellow is OK? It seems to me that if they are connected then the oil would run out the white hole. So I am assuming the the white hole is the over flow drain for the TA and that the TA is not in the same sump as the gearset. Correct?
Pete 23, I am using the hytran even though my TA is toast. Judging by the nasty goo that came out I"d say a previous owner did use gear oil though.I never get upset at a reminder though. :)
Thanks all!
 

Correct. The white hole is not a check level plug, and is in a different cavity from the yellow hole.

Notice the red hole and the yellow hole are at the same level.

IIRC the yellow hole is up in the cavity where the live PTO gear is.
