Why does my transmission keep failing on my Yukon xl?

I am having transmission issues for the 3rd time since owning the car. I bought it in 2015, it is a 2005 with about 165k miles. I have had to have my transmission rebuilt 2 times, why does it keep going out. Or getting stuck in the 3rd gear?
Any information is appreciated

    Are you doing any excessive towing or hauling? Either the person rebuilding your unit isn't doing a good job of rebuilding/replacing internal components or your have electrical issues indicating a false rebuild of your unit.

    Has your radiator & transmission oil coolers been replaced each time the transmission is replaced? Flushing of the components usually doesn't work as debris is still stuck in the system.
