I changed my 4L80E fluid at 280,000 and it did fail. On a closer inspection by a shop it was wet wiring causing the fail. That was updated and it’s going fine now.
The harness is a somewhat common failure mode, I had to replace mine when I rebuilt it. Super easy to do while you're changing the filter. I ended up dropping the pan after the rebuild to change it. I potted the back side of the connector with grey RTV.
