Some of it perhaps. The 700R4 came thru a long and painful gestation with many changes to the hard parts. Depending on what years the kit supports will answer what, if much, is usable. You've got to get to a 1992 4L60 version of the 700R4 before you get serious hard part compatibility with the 4L60E.
Keep in mind the 4L60E is electronically controlled, the 700R4 and 4L60 are not. The 4L60E's valve body is way different and has it's own problems vis-a-vis the 700R4/4L60. It also has a bunch of internal wiring that needs to be replaced with a rebuild, by the time you do the differences between 'em it will probably prove to be less expensive to just buy a 4L60E kit.
