the Edge works just fine and Im sure no chip or controller would work fine too. Mine runs great with the Edge EvaluationAn edge won't work you have to use a hydra or ts 6 position with tunes for a manual pcm code.
CHEVROLET HAD 4 ON THE COLUMN IN A VAN BACK IN THE LATE SIXTIES.....SO.....MORE THAN THREE HAS BEEN DONE.....I wonder if you could do a 5 speed manual shift lever on the steering column? hah. thats the only logical place for it on a van. I've only ever used 3-speeds on the column, no idea if the column shifter concept works with more gears.
I AM SURE THAT THE U.S. MANUFACTURERS MADE MANUAL SHIFT VANS FOR THE WORLD MARKET THAT WE NEVER SAW IN THE U.S.A......MAYBE SEARCH THE U.K. EBAY SITES FOR REFERENCE?....Wow, it's been a long time since I drove a 3 on the tree. I think Mercedes did 4 on the tree too, back in the 1960's. Not something I'd wish to re-create though!
But remember the step vans that UPS and others used? They used to have manual transmissions. I'm pretty sure I have seen them where the stick comes up through the floor, about even with the driver's butt. Then the shift lever bends forwards in an "S" curve so the shift knob is in a reasonably normal position.
Ah, here's an E150 image:
