1997 chevy k1500 r motor 5.7
so tried to read entire Tonight on my 1997 k1500 r motor because i want to try and see if there are options to avoid taking my personal plow rig truck trans out and apart. i will spend the $100 to tune to either boost pressure and or shut off tcc and p1870. it won't read. i remember somewhere i read about these trucks being different than the norm gen 3 and need to do something first?.?. please let me know what i am missing. i know it's kicking around somewhere around here. i just ain't no good at lookin.
