Transmission tune

[defxtones]

would anyone happen to have a performance Transmission tune for a 05 4L60e the downshifting on mine is horrible and I’ve tried to tune it better but I can’t get it the way I want it I want it to aggressively downshift cause that’s when the truck takes off I lucked out by getting a performance transmission with a stock transmission tune

from my experience that has a lot to do with HOW the transmission was built i.e. the parts that were used inside of it, clutch packs, valving, etc

Although this is true to a point, the way the transmission responds to - or ignores - the driver's right foot is more to do with how the shift tables and kickdown tables are written.
GM wrote the 'Normal' Up/Down Shift table to discourage 'fun' driving -
and they could have made the Tow / Haul shift table Tow-ier / Haul-ier.
(Since I don't tow, my Tow / Haul shift table has been written to behave more like a 'Performance' shift table.)

I don't have the software to help you tune yours, but my tuner let me write my own shift tables.
Maybe I can help you write yours? I've plenty of experience tuning mid-90s LT1s, if that helps ...

I sometimes drive with the tow button on in the mountains on my 2012, even without towing because it helps save the brakes on steep/curving downgrades. the 2010+ have a transmission brake assist that is enabled with the tow haul button on, then in 2013 I believe the option is automatic without the tow button on along with hill start assist.
I asked BB if they could do a transmission sport tune with the tow button but they said with the 6spd it's too difficult. the 4spd's can be done though.
funny though on my 18 silverado with the 6spd it's a different beast when you are slowing down it sometimes feels like a manual transmission shifting down gear by gear

theres a program called the "blue cat trans tuning tool" its a free dl, theres vids on yt to see how it works. and i for one have used it, it might take a bit of tweaking to get things where you'd like em, but you'll get much closer starting with the blue cat tool.
