i have a 2011 Durango with 5.7L and i noticed when writing the tune that it didnt write to the TCM. why is that? does the 91oct tune not make any changes to my TCM? it always has in my other vehicles... just wanted to check if thats normal or if something is wrong here...

i guess im a little confused then. by TCM, im refering to the transmission control module. are you saying that i dont have one? what controlls the transmission then?

It uses a powertrain controller, which does engine and trans, not uncommon.

Got it. Thanks. So now out of curiosity, does the 91oct tune make any transmission related performance changes on my particular vehicle?
