Thank you for all the responses.
It is the Kawasaki engine and seems to be original but I'm having a hard time finding numbers on it to be sure it is the FH680D. You never know what somebody could have crammed in there as a replacement.

I've already chased down most of what has been mentioned above. From what I can see it seems to be a pretty idiot proof system and I have a hard time imagining that somebody could put the transmission together incorrectly and still be able to run it at all.

Another problem I stumbled onto thru all of this is that when I got it the front drive shaft was not installed. I hooked it up and now I can't back up. it seems like its fighting against itself. I'm gonna put it up on blocks and see what direction all 4 to turn and go from there. I just can't believe that the trans is put together wrong but I suppose anything is possible. Anybody out there have a good diagram of the internals on this transmission?
