your thinking is a little skewed, there is a 700r4, there IS a 4L60, and there is a 4L60E (we all know that one atleast)
the 4L60 is a non-electronic tranny, like the 700r4, but the electrical connector on the passenger's side has 5 wires running to it, as opposed to the 4 that a 700r4 has. I'm not sure if the extra wire runs the lockup solenoid or what, but there IS a difference.
'93 f-body's and corvettes I KNOW for a fact had 4L60's with a throttle valve cable, '94 started the 4L60E with the on/off lockup like a truck does, and '95 started the "pulse-width modulated lock-up clutch" in cars- basically a converter that makes you think your tranny is slipping in to overdrive when it locks up- bastards! lol
as far as internal guts, I don't know what the difference is, but there IS such a creature as a 4L60.
