The 6.0 is not tied up to the 4L60E. I know because I have that engine. It's tied to the M70, a heavy duty 4 speed. There was a TSB on the transmission because they changed the programming of the shifting. Even mine shifted funny between 1-2, but after the reprogram it shifts smooth and crisp now. And I sometimes drive hard, with no hiccups from my tranny. In fact I stoplight raced a Tundra and last gen Escalade EXT this week and smoked em both.

I place the blame on edmunds, they obviously abused the hell out of that transmission before going for the update. And what the heck, I'm sure a few out of hundreds of thousands of trucks sold are going to get a bad tranny, regardless of manufacturer.

Doesnt matter anyway, the 6 speed used now is flawless and strong.
