I know if you already have the care and love it is hard to think about but it would be cheaper to just get a dolly or a manual transmission car. In addition to any transmission pumps, etc. (prob $1000) you would need a baseplate ($200-600) a tow bar ($200-800) and a braking system ($100-1200). For $300-1000 you can get a good dolly and be done with it, if you want to keep the car.
I know Honda says you can't do it, but Remco probably has the parts you would need. Voids all warranties, although with a 2009 you probably are not worried about that. Sorry can not help with the specifics but have done some research in the past and decided to not try it. I currently have a dolly but usually tow four down now with my manual transmission Jetta TDI.
