Got this from http://www.gmpowertrain.com/transmissions.htm so it really
only applies to current transmissions.  Not sure of the ratings on the
same transmissions in the past.  I am pretty sure the 4L80-E and 4L60-E
are the same since I remember looking at them a long time ago. 
Interesting is the difference between the 4L80-E and 4T80-E as well as
the L and T versions of the 60.
