Tcm torque table

If I was to drop the torque in the tcm trans table would that keep the trans from going into limp mode no matter what tune I was running.
I am just thinking out loud.
Thanks Darryl

Simple answer is no , it would stop the fueling tables from ever making more power because you would never hit full fuel , so any tune you flashed would be over ridden by the tcm / base torque/ TLIQ .

The truck doesnt know how much torque it makes , there is no torque sensor any where to be found , the torque #'s you see in tuning are simply hypothetical #'s used for fueling reference .

Thanks Trent,when you guys were talking before about adding torque I was wondering about taking away torque.
Thanks Darryl

Wait, is the torque limits table in the tcm what torque the tcm wants the engine to make during a shift defuel? So during a shift at 3100rpm the tcm wants the engine to make 494ft.lbs.?

If I am right this whole defuel thing is going to make a lot more since.

Does it take the trans torque limit table and call it DMAX Max Torque?
So when you see DMAX Max Torque drop during a shift it is referencing the torque limits table in the tcm?

But what does the ecm torque table do?

Go do some testing , that will tell you everything you need to know .
