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.

This is a result of ridiculous gas mileage standards. A 6.2 V8 does not need 10 forward gears, but to squeeze fractions of an mpg to avoid billions in eco-religion fines, this is what you get- cheaply built, over complicated, error prone, junk. That said, the 10 is generally far better than the 8 regarding lurching, clunking, gear hunting, and premature failure. Hopefully the current US administration will be succesful in rolling back all the eco no sense and let automakers produce good stuff that consumers actually want again. The last 8-10 years will be seen as a dark spot in automotive history, similar to the late seventies through late 80s. Give us back our bulletproof smallblocks and 6 speeds!!!
