my 04 tahoe is AWD and i am thinking about swap to autotrack push button 4WD my gas mileage sux. like 12mpg with 3.73's. now it also has stabilitrac so when a tire spins it will close the tb and apply brakes as needed. if i swap to autotrac then will i have a problem with the stabilitrack or will it only be a problem when the back tire break loose and not the front? it has a button to turn it off but when you turn it off it only disables the ecu from removing eng power but it still applies the brakes as needed. i know i will need a new front diff to do the swap as well as the buttons and t-case. what else might i need?
