Shifter like this.....
A switch is a switch is a switch...regardless of whether or not the button is depressed from the side or from pulling up. I agree that the decision to exclude this was a cost-driven decision, but for crissakes - this is supposed to be GM's hail mary pass to get the company on the road to recovery. I would have gladly paid another 50-100 to have a retro shifter that paid hommage to its big brother!
The Hummer shifter is close, but it's missing a leg and the button is still depressed from the side.
If no one offers one, I just might take this on as a project, but to do it right would basically require a new molded center console cover to allow for the two vertical legs of the staple shifter to travel back and forth. Might as well make it a ratchet shifter too....hmmm more tricky since its got Tapshift. Put a couple of microswitches in the shifter housing, re-route the switch leads from the steering column.....could be a good winter time project.
