    Just curious. I know they are a weak point on these vehicles.

    Please include year, mileage, maintenence schedule, and any mods to the vehicle

    • 2002 Tahoe Z71
    • 280,000~ish miles
    • Essentially no maintenance done on the transmission. Maybe an occasional fluid change. But none that I am aware of. I've known the car it's whole life as my parents bought it new before giving it to me a few years ago.
    • No mods

    • Still on original transmission with ZERO issues. :)

    2006 with a 6.0L and a 4L65E at 115k. Bought it with 74,600 miles. OEM trans died at 86,000. Rebuilt, fluid changed at 1,000 miles after the rebuild, and since been blackbear tuned with a spectre intake and a magnaflow muffler. No trans issues since the rebuild.

    I drive my 2001 Suburban like I stole it, pretty much always did ever since I originally bought it back in 2006 with 52k miles on it. I installed a Vette servo and got a Blackbear tune in 2010. The sunshell in my transmission broke apart at 118,000 miles in 2012. When I had it rebuilt, the shop told me that the clutch bands appeared to still have a good bit of life left in them. Nonetheless, I had the the transmission completely rebuilt, not just the broken sunshell replaced. Not a single issue since it's been rebuilt, and I still drive with a really heavy foot. I originally thought that perhaps the tune had something to do with the transmission failing so early. But then again, I now realize that it was a bad combination of the shitty GM sunshell and my lead footed driving style.
