pathfinder motor swap, first timer

[atckilla]

sooo. I was given this 91 se pathfinder by my dad, and he said I can have it. It's got a brand new transmission, but a bad motor. I bought a used motor, got to hear it run, but watching them remove it seemed to be a pain, I'm used to ka24 or sr swaps, I've done a bunch of those, and they're easy, but the oil pan hitting the front diff/susp seemed to be an issue. It's an auto, but i was wondering what the preferred method was doing the swap(leaving the transmission in, or taking it out with the motor) or any tricks you guys know that would make it easier for me. Also is there a fsm to download anywhere? thanks alot!
