In that case, take the stick sleeve off, install an AT one in it's place.
Don't have a sleeve for an AT, you say? Fine. Grind the shifter lug off, do a little "body work" on it, repaint and reinstall.
What I'm getting at here, is you do not need to change out the whole column (along w/the wiring, etc.) in order to get to where you wanna go.
