I have had good luck buying from importers. The first two transmissions I bought used on ebay that were from the US were both trash, noisy bearings and such. I then started buying from importers and so far have not had anything go wrong. Ten purchases of major parts now and many smaller parts, I am sure someday something will go bad.
At this point I would rather buy an imported engine or trans since I can not rebuild one for the prices I have been paying.

Cheers, Charlie
