    The latest version has everything you mentioned.

    No I.S.S. tab ... solenoid parameters for 2008 and earlier T42 only ... FYI

    So the speed sensor is the 80E is compatible? The 70E is integrated in the housing and differs from the 80E. Just want to make sure the actual output signal from the ISS is the same. Reads normally by the TCM?

    Yes. They're all just magnet type.

    OK, I opened a 2008 file, and can turn off I.S.S, and the 2-3 solenoid etc..

    Any chance I could get a 2009 Colorado 5.3L T42 support added? I'm doing a 4.8L/4L80E wiring harness, is from a 07 4L60E, and does not have a I.S.S sensor, would be nice to not have to add it.

    Guess I need to have these added to my 0411s 1221156 operating system, for the day I switch to a 2.75 low gear planetary set in my 80E.

    I was trying to get this to work on a 2005 GTO with a 4L8DSteck0 swap and I think I did everything like was explained on here and the link to the post on the LS1GTO site but was running into the issue that DSteck ran into with the torque converter not wanting to unlock. I do not have the input speed sensor installed waiting on a connector but I think I have it shut off. Does that need to be functional for the TCC to work properly? I tried putting it back on PIN 25 and turning the enable solenoid back on but did not add the relay yet to eliminate the codes and the TCC never locks. I was just wondering if someone has got this working and can share the tune or what all needs to be connected? I thought I did everything correctly but feel like I am missing something simple.

    Thanks
