Welcome to the Mr2 community and congrats on the Mr2 purchase. Ideally a manual trans is the way to go with these wonderful cars but if you must go with an auto...then so be it. Keep in mind some owners do a auto to manual swap and there are DIY's on how to do it if you are ever so inclined. Here are some great sites that may be of help to you, mark them as "Favorites". Good luck.
