Nismosentra1

So I have a 1992 pathfinder I got for free with a bad transmission, was able to find one and installed and when I drive it in D range it seems to struggle up to 3rd gear but if I start out in 2 range and up shift to D at the top of 2nd it seems fine...has no power to pull obstacles in D but pull to 2 and it goes....guessing I'm needing another transmission?....if so which ones will work on mine and what do I need, I only wanna do this 1 time more...I am also a 25 year nissan master so I can do it just need info outside of what the parts manual shows

I have a 1992 pathfinder 4x4 which I got free due to a faulty transmission, I was able to find one and install....now when I drive it in D range it's seems like it has a torque converter stall, like won't barely pull hills etc....if I drop it to manual 2 and shift to D at the top of 2nd ,that way seems fine....guessing this trans is no good either...so what tranny's will work and what EXACTLY do I need?
