Tcm tuning is available for early model 15 trucks. We build a ton of LML transmissions also, if your looking to reliably push past the 600hp mark.

Do they void warranty? And how are thwy done? Physically or with a computer? I am close to mike l transmissions.
I prefer to skip the bs tunes and just do a proper build and good converter. Makes a world of difference and you know it will hold power and last.
No, Why? I didn't state any brands, companies, or shops. He asked if there's any mods, and lots of people build them. Perhaps I should have said many people can build them instead of "we", I apologize if you felt that was advertising. Was merely explaining you can build them and its recommended to do so at 600+.

I have more experience on the '15 than most. The pump and valve body kits available for the LML are mine. I had the prototype LML Allison a year before the truck was introduced. I think I know it well.
Mike L, do you have a website? I was looking to do a Transgo Jr for my 2011 LML but If you have other/better options I would like to check them out. Also I thought you could change line pressure in the TCM tune? I haven't busted out my LML tcm tune yet but I looked at my old LMM tune and I didn't see options for line pressures.
Line pressure is adjusteable via tuning, BUT we don't have access to it. As of right now you either can get a pressure box or ppei tcm tuning to change line pressure electronically. And theres no transgo jr because the 11+ basically already have it in them.
You can pull the pan and unplug the factory pressure control solenoid and add a dummy solenoid part number 29541895 to keep from coding and get pressure constant. If you ever build the Trans properly remove the dummy solenoid and plug the factory one back in.
