AutoTrans Swap

I just got my beloved and only 2 weeks later my transmissions went. I dont like 5speeds cause i only make 10min trips(too much shiftin) but i wanted to know if there is another auto transmission that would make it faster off the line? How about the tranny from the new outback? I heard of people taking the turbo legacy 5speeds out and into a Svx but how about a automatic? I can get a rebuilt tranny from Subaru for about $2k should i just get that and be happy? Well any input would be great!!thanks
