4l60e/4l70e

Is there much of a difference between the two? If so, what?

More hardened internals, 5 planet gears vs 4 on the output shaft. That is all I know of.

The 70 is just a stouter version of the same thing.

The short answer would be that the 4l70E is a heavier duty transmission (found on Vortec Max trucks with the 6.0L )than the 4l60E. That transmission can better handle the higher tow ratings.
