2001 Honda Odyssey Transmission: Reverse: Properly Installed

Here is a documentary showing my Honda Odyssey Transmission (2001) that I am rebuilding. When I completed the rebuild, I had no reverse, in fact the van surged forward slightly in reverse. After taking it back apart, I discovered the reverse gear selector was upside down and pressing hard on the selector fork. Although I DO NOT think this is my problem (No Reverse), I think this is a VERY easy mistake to make so you can learn from my mistake!
