Default swapping a 4L60E for a TH400?

How hard of a swap is this? It will be on a 98 Z28 What supporting mods will I need to do this?

Shouldn't be any harder than swapping any other auto trans. Probably need new torque converter, new crossmember, and modify your existing driveshaft. Not sure about the flexplate or the shifter. You should be able to use your existing one. Thats all I can think of off the top.
