Will a 4.3 with a 4l60e tranny swap out with
a 4.3 with a 700rstranny with no
modifications. Or can I swap the trannys
with out taking motor out
The big difference obviously is the "e", the electronic shift. The 700R will require a kickdown cable and all that or it won't shift properly. If you have a 4L60E then you should stick with that.
