Car won’t roll backwards

[MyCarWasFree]

So I was driving my 2010 Yaris 1.5 with the automatic home the other night it started to shift kind of hard and then lost high gear all together. It would just get to third and got to shift and would just rap out like it was in neutral. I got it home as it was only a few hundred yards down the road. I changed the transmission filter a fluid as a last ditch effort to maybe save the transmission. Now when I put the car in neutral with the engine off it will only roll forwards. When I try to push it backwards it acts like something is binding. Any thoughts pointers or ideas guys? Otherwise I guess I’m looking for either an engine/trans swap or a just the same transmission that came with the 1.5.
