215,000 here, and just went through the the original 4l60e. It has had the 'ol cold piston slap on start-up since I bought it at 32,000, but still runs strong and doesn't use or drip any oil!

Just over the 223,000 mark here on my 99. Starting to use a qt of oil in between changes but she still pulls pretty damn nice for the mods. She's gone thru 5 maybe 6 transmissions, 3 tq's, 1 g80, 1 water pump and now I have a crack on the rad end cap. She is just starting to show her age, which was expected but as far as the motor goes, she's got a good strong tick to her.
