Mine just took a dump at 188k miles. It has had a stall in it for roughly 40k. I have taken it to the race track many times and it was driven like a race car daily. I kept the fluid and filter changed, and run a RV trans cooler.. If an auto is dying below 100k miles with mild modifications then it has either not been taken care of or the tuner "tuned it to death" meaning they ramped up line pressure too high yadda yadda.

I'm glad to see that the 4l60e tranny is more reliable than I first read. I just passed 67,000 miles, and it still feels strong. No laziness in the shifts, 1-2 is very snappy, almost wonder if it has a shift kit in it, or if they came that snappy from the factory.
