    A50 is presently in development. A few OS's have been mapped (but haven't made it into beta), others cannot be mapped due to changes made within the ECM/OS structure.

    Cheers

    Cindy there was a mid-year change to the LML TCM. The 2015.5+ trucks with the RPO code "AVF" have a digital/DC output speed sensor instead of the normal AC variable reluctance type sensor that has been used forever. The 2015.5+ w/ AVF TCM's have different wiring too (IE, if you compare the pinouts side by side of 2015 and older and 2015+ w/ "AVF") there are differences.

    I might even guess that MAYBE the hardware might be updated/different too...because looking at the pinouts, some things dont even come close to matching up (IE, on the 2015.5+ trucks, a certain pin is "ignition hot +12v feed", and the other 2015 and older w/o AVF TCM, its a pin for something significantly different such as a speed sensor, or a low-side driver for one of the solenoids.

    I think Ben works at Allison, he's just not letting it be officially known
    I no longer monitor the forum, please either post your question or create a support ticket.

    You don't need to work for Allison for that one... Mapping DTC is pretty easy, just time consuming!!! Lol
