I had to take the bottom of the transmission pan off to get to the inside and some parts fell out because they were already loose and I don't know where they go. I need an illustrated shop manual to fix find where these parts go so I can reassemble. Where can I find one? The service manual does not illustrate.

As a general rule no info is available from Kanzaki. Surprise, surprise there is a YouTube video. Do not believe everything you hear in it. I knew better almost immediately was the fact that He cut the axle covers(hubcaps off.) you can get them off.
