ran across a motor/trans from an 07 trailblazer ss. 50k miles. So what is the difference between a 4l60e and the 4l70e? Still use the same converter? What else. Doesn't need to be in gret detail, just hit the high spots. thanks.

In broad terms:

Stronger 5 pinion planetaries.

Bearing style reaction carrier, rather than thrust washer.

It will also have a ISS input speed sensor. But a Gen III PCM will work with it you just don't use the ISS portion.
