How has GM not fixed the 10-speed?

I genuinely don’t understand how this transmission is so bad? I had the dreaded valve body issue, and instead of waiting on a list 3500 deep, I got a full OEM transmission swap as I am still under warranty.

The new one still occasionally lurches when downshifting, and consistently hunts for gears.

How has GM stayed competitive when their transmissions are just….bad? Even my Ford with the same 10 speed is significantly better.

… bought a brand new 2018 Lexus 350RxL (stretch) and for the 3 years I kept it, the fucking Jatco 8 spd would annoyingly hunt for shifts. Had to run in Sports mode to get any relief from the hunt but the gas mileage crashed. A primary reason I could not wait to dump that overrated piece of crap and will not look at another Lexus.
