That the 8x8 mechanical shuttle? Basically the same transmisssion as the Ford 30 series used?
If it's the same one... then you likely have shuttle syncro that crapped out. The bad news is... the shuttle syncro is the first bittie piece that goes in during assmebly... from the rear. So... you get to remove the transmission, remove the rails and forks, remove the front housings, stand it on the clutch housing face and start pulling the rear housing off... then extract the mainshaft, drop the countershaft... and then you get to remove the 2000 dollar syncro. I've had one apart twice in my 3930... IIRC it was about 40 hours work to remove the transmission, disassemble, repair, reshim and then reinstall... SOmeone that was more familiar and was working in a well equipped shop could probably do that a bunch quicker than I did... and mabey the Kubota is easier to split open... but this one had a full loader frame and various other complicating factors.
