As Stamp said, your fuel pump, fuel pressure regulator, and all with the fuel delivery, are good enough to run decently. I'm trying to figure out in my mind what you did by r&ring a transmission. I read an earlier post that stated, a friend helped me, and I had no codes. Basically theirs fuel and spark, that make any engine run. The thing that stumps me is you say it starts then dies. What involving the motor did you disconnect, when you replaced transmission? Am I missing something here. Did it run fine before transmission swap? You need to back track every wire you disconnected, that involves drive ability. I just can't believe injectors, or any other sensor went south, doing a tranny swap. Make sure all grounds are clean and back where they should be. You've eliminated the fuel delivery from the tank, after all visual inspections, of any wires, or hoses, then it's time to read cylinder temps, and if you find one or more low temps, then it's injector firing, replacement of injector time. You'll need to use a noid light to be sure all eight are firing. Keep us posted, this one of the tougher ones.
