I am putting the engine and auto trans from a 98 GXE (only 112k on it but the body is trash) into an 01 SE. Are there any significant differences that I need to be aware of? And are there any tips/tricks to know for doing this swap that are application specific? Any and all advice to make this faster and easier is appreciated. We need it drivable asap. I'm experienced in general but I haven't swapped one of these before specifically.

It will fit right in. Everything is identical on this generation Altima. Nissan hit it out of the park with this vehicle. Don’t ever get rid of it, they keep on going!

This is not a true statement: there is a diference between the re4r04 trans's it has to do with the shift linkage: the adjustment for the 98 trans is done at the transmission arm whereas the the 01 adjustment is done at the transmission shift select arm. the cable from the 98 has to be modified to fit the transmission arm and requires a bolt to fit the slot of the transmision arm to allow movement of the arm and cable to pivit together. the 2001 uses a fix position arm with a rotation center spacer to allow movement.
other than that they are internally the same. I made thisa change in a 98. sky5031

One thing that I forgot to bring up is the transmission tcu connection : 2001 nissan made two version of this 4e4r04 trans a "A suffix"
and a "B suffix" "A" was the beginning of the year and had the same cable connection that the 98 has on it, midyear nissan changed the connction on the trans to a connector plug which wouldnt connect to the 98 trans harness without some wiring changes. There is a trans part supplier that has a cable that will work on the 01 trans to make it work with the 98 harness if you run into this problem
search repairs and cable for nissan trans. sky5031
