The Allison is electronic, no shift linkage. Allison has a little shift box with buttons and a display that can be mounted on the dash or console. I'm not sure how you adapt that to the GM wiring harness, could be simple, could be difficult?
The short answer is there is probably a way to make it work without a column shift.
