I can get you any parts that you need, may have to special order some from China though. But I do have that capability. Do you have parts schematics for the tractor? I have those also. We have done this many times here at our shop.
Another way to go about this is just order the whole transmission from China. We have done this a few times.
Let me know if I can help you out.
