The 8630s had a lot of engine problems as well & most have been updated to the 8650 engines. Make sure the one you are looking at has been updated. Don't know about tranny problems. Friend had a 8630 that had a 425hp Cummins in it & he ran it for several years without any problems. I didn't run JDs at that time but if I was you I'd be looking for a 8650 just from what I have heard if Iwas wanting a JD. Otherwise I would look at a Versatile. Cheap & dependable but like any other tractor it depends upon how it has been treated.
