Looking to change fluids in rear end as it looks like its a bit milky. This is my first TA tractor so just want to make sure I am doing this right. Have the owners manual & the service manual and did a lot of searching and am still not positive on a few things. Pulled the two plugs on the bottom of the rear end last night and been letting it drain. I see another plug below the TA section, do I need to pull that one too? I have 15 gallons of hytrans to refill it. I see the filler plug on the deck like my H, but do not see a separate filler for the TA section. Not sure if the TA section is separate from rear end or not. I see the two level check plugs on the side. Thanks in advance, Dave
