The h23 tranny would be better, it will bolt up. The f22 tranny or h23 tranny will bolt up. I would recommend the h22a automatic MP0A (non lsd) or the automatic MP1A (lsd). Remember that you HAVE to swap out the TCU (transmission control unit) that coincides with the new tanny you get if it is other then an automatic h22 if that is what you have. If you dont then your shift points will be out a whack and you'll throw a check engine light. Anyhow if the h23 tranny is the one you get, look for a p14 TCU. Also make sure that you have the torque converter off the h23a tranny, you will most likely need it.
