automatic transmission (RE4R01A) ?

[killahbeatz]

I have a 89 240sx. My automatic transmission went and I am looking to replacing it with an other automatic transmission. I know that my 240 transmission is a RE4R01A which is used in the 240sx 89-98,300zx 89-97 3.0L w/o turbo,pathfinder 88-98 4x4,929 92-95 3.0L,mpv 89-99 3.0L and the rx7 93-96. Does any body know if I have to change any parts on the transmission if I get it from an other car that is not a 89-90 240sx. I was looking to get the transmission from a 96 240sx at a local auto salvage but the auto salvage guy said that his computer shows the 96 240sx transmission not being interchangeable with the 89 240sx. Can any body till me if he is correct or wrong.
