This one might be kinda far out... but could it be possible? If you already have the automatic, i think it might work, imo... but it might not because the Rumion is RHD...
so could it be possible with a swap or custom fab?
It would seem like it might possibly, but I honestly have no idea how the mechanics behind it work. Although if someone somehow made a setup up to covert us xb guys over to I'd deffinatly be in line to purchase it. If its just a switch that should be cake right?
If you get the parts, it shouldn't be too hard. I assume that when you move the lever up/down on the shifter, its completing a circuit momentarily. If this is truly how it works, then all you need to do is to find the points that need to be connected, and wire into that. I could be way off though. Best bet is for someone to get a parts diag. of the shifter unit, or even better, a shifter unit from a wrecked xB, and break it down.
