I changed the transmission fluid and filter on my T2290 w/245 hrs. Kubota says to change it at 600 hours. It took 3 qts. of 20W-50 oil. I went with Castrol GTX with the higher zinc content. I had to unbolt the axle from the frame, and lift the mower up away from the axle to access the fill plug. There is no way to get a funnel in there with the frame just above the fill hole. Dumb design on Kubota's part.
 
Doubt a trans needs any zinc at all.

Most oils have similar zinc levels these days. Not like one brand has a considerable amount over brand Y.

How did you drain the oil from the trans axle? Did you suck it out with extractor? Sounds like you had to unbolt the trans axle anyway to properly drain it. Most people never change the oil in a riding mower trans axle, because many of these are considered “non serviceable.”

Removing the oil filter drains out all the oil. The hardest part was refilling with the new oil.
