Too bad you drove it home, if you had caught that when it blew and immediately parked it, you probably would have saved it. It is most likely toast. In rare instances you can refill and still have a serviceable trans but it's life will have been shortened dramatically. Pull the pan and be prepared for the worst, it won't be pretty. As to what transmissions will fit from other Isuzus or Hondas or GMs, I can't say, but there are others on here that can and I'm sure they will. Best of luck!
