Backward shift pattern usually indicates that it is an overdrive transmission. If you have ever heard the expression "Throw it up against the dash." That's what they're talking about. I can't remember the designations right now but the same transmission is available with the standard shift pattern. If memory serves correctly the overdrive is about 27%.

Edit to add: I think I remember that the "turned around 8 and 9" is designated by the letters RTO and the standard shift pattern of a 9 speed overdrive is RTX, but memory is sketchy at best as I haven't dealt with any of this in several years.
