TURBO-CHAIR

Hi guys This is my first post so here goes. I'm looking at getting an Impreza P1. The only issue I have is that I'm in a wheelchair and so need an automatic gear box so it can be driven with my hand controls. Can anyone advise on which box fits what engines? I'd like to keep with the 2.0 turbo engines, would a forester gear box fit to an impreza engine? Any help and advise would be much appreciated. Thanks Ollie
