Re: 4l60e, 4l65e, 4l70e ?

the 65 is is a little stronger and updated 60, and the 70 an updated 65 also I think.

As far as the 80's internals don't know, never been in one, but they are physically bigger , as in bigger cases, so to me that means beefier internals. I also think that the tourqe convertor is a little bigger in diameter, that makes it easier to make it more effecient, so there IS less power loss through it.
