What choices are you guys making in the install part for the trans tuning software? It asks if I want to change 5 & 6 gear shift points, and shift firmness. For those who haul heavy, what are you choosing, and how is it working out?

OK then I guess I'll stick with the defaults.

I wrote my own tune with the MCC back when I was still driving my 2010. But, if I remember the stock tunes, I raised everything, and adjusted shift firmness to the max. I like hard shifting.

Been a day or two though.

Thanks, Chris, I think I going to experiment with the settings, and see how it works out. Do you pull trailers with your truck?

Yes, 35' 24K flatbed gooseneck...usually overloaded. We would gross out over 40K on occasion, sometimes nearer to 50K.

Went with defaults on shift firmness & 5 & 6 gear shift points, but didn't change line pressure. Seems to work really well.
