Why are you yelling. ALL Capitals are difficult to read, or is your caps lock stuck?

As you say its a Farm truck, if your not worried about oil on the brake shoes ( I would be) then excessive oil in the TC and low gearbox oil is also not a major problem. Just drain the excessive TC oil and top up the gearbox, check every few years, not worth the effort to replace a seal for that issue . The gearbox will leak of its own accord even with a new seal.
