I purchased a "Nexmo" transmission from a guy on ebay. He has another one currently listed on eBay. Just key in American Iron Horse parts, and it should come up. The guys name is Brian, and he is a great guy to do business with. The "Nexmo" transmission is an upgraded Roadmax and much better. It's a direct replacement, and works great, it is also nicely polished. I purchased one, fast shipping, and packed "bullet proof", also very reasonable for a great transmission. Hope this helps. JJ
