2017 5.3L with 6 speed - will a tune make my trans shift firmer/better? 6L80

[TahoeFL2017]

2017 Tahoe 6 speed, nothing wrong with it, just occasional "hunting" for the right gear, and random slow shifts here and there

Reverse back to drive sometimes like to shift weird if you don't wait for a sec before hitting the gas.

Will a tune help this?

Appreciate any feedback from those who have tuned their trucks!

The most obvious thing a trans control module tune does, is it makes the transmission act less like Buzz Killington,
and more like a friend who wants to encourage you to drive however you feel like driving.
If you are in an enthusiastic mood, it won't hold you back nearly as much as GM does.

If you want something more bespoke, best to discuss with the tuner at length before purchase.
