That should be a Jatco JF506E transmission. They commonly have an issue where they lose reverse but have all the forward gears, to see one the opposite way is rare but not impossible. The most common reason for loss of all forward gears it is a broken retainer clip on, or the outright failure of the low clutch drum.
The same trans was used by VW as the 09A, if you google 09a self study guide 232
you can get a pretty good idea of what you are facing inside.
