It's the newer ones I am worried about. I had a 4L60E disintegrate at a relatively low mileage and since then am skeptical.

The 4l60e isnt even in the same ball park as the 4l80e. The 4l80e is basically a Turbo 400 with OD electronically controlled. Even in stock form its one of the best 4 speed autos out there.

Do some searching on performancetrucks.net and you'll find many swap to the 4l80e when adding power mods to their vehicles.
