Just a heads up that I have uploaded the Transmission Assembly guide to :
https://evtechnicalservices.com/onli...embly-document
It's the document used when these were put together from component level in Wisconsin using the parts which were here since 2012.
A common issue is the transmission will pop out of gear and not move. Sometimes the casing gets damaged and there isn't much you can do with that, but on some units built in WI they forgot to install the snap ring on the input shaft. This would finally end up with the gears no longer meshing and your Vanish sitting in the woods while the motor can run but the wheels do nothing.
The document is still half in Chinese, but the photos should help anyone trying to get an idea of what's inside the thing. Good luck all!
