The 4L65E was a little better and the 6L80E is MUCH better.
The 4L60E was rated at 600 Ft/Lbs in first gear (engine torque X 1st gear ratio) and the 4L65E was rated to 650 Ft/Lbs, while the 6L80E is good to 800 Ft/Lbs...
The ultimate GM transmission was the almighty Allison 1000, hooked up to the Duramax's!

That can't be right the auto Camaro makes 395ft/lbs X 4.03 (1st gear ratio) ~= 1500
