Grinding noise in mid gear only- Kubota B3200

[WarrenPFJr]

So yesterday I suddenly started hearing a clicking noise while driving the tractor, almost as if it wasn't all the way in gear. It happens in mid gear only, doesn't matter if Im in 2WD or 4WD. High, Low and reverse all work normal with no noise. Hydrostatic fluid is topped off.
Im in a 2009 Kubota B3200 with about 1000 Hrs on it. Im afraid its my transmission. Any other thoughts to what this could be?

Thank you!
