a 4l65e is beefed version of the 4l60..65 has heavy duty input/output shafts, 5 pinion planets, and heavy duty shell..if you know how to build trannys you can buy the parts and put them in a 60....
4l60/65e is electronic it has no vaccum modulator

FYI...It is a very poor idea to purchase trannies based on somebody's horsepower claim. Horsepower has very little to do with auto trannies and how they hold up. Get a input torque rating on the tranny before you make decisions, that is the number that actually means something.

that use the 5L40E. I guess that says something for our "lowly American cars" If memory serves the 5L40E, at least in the beemers, weighed ~250lbs. I can't say that I remember the exact weight of the 4L60 and 4L80, but I'm guessing the four speeds are much lighter than that.
GM should start thinking about putting a five speed auto in the C6. It would make a hell of a difference.
