    ISO .bin file for 4.8/4L60E with OS 12587603

    Hello!
    I have a 4.8 with a 4L60E and I need a .bin for it. My OS is unsupported, so I am trying to find one for 12587603. All of the .bins I have been finding are either the wrong OS or they are for a 4L80E and in tunerpro it specifically says not to change the trans type. Does anyone have a .bin for this or any suggestions?

    Hello,

    Let's see if this works and I'm not sure where I got it - probably here. But look it over closely with Tuner Pro and let us know how it turns out.

    Thank you! I looked it over and it's for a 5.3. I will be way to rich if I run that I believe.

    I segment swapped and built one. You may have to copy your injector data and MAF calibration parameters in to make it run well. I also lowered the shift times by 10% so use at your own risk. VATS is also disabled.

    HTH.
