    I believe you can modify most all of the 5 speed gen 3 style TCM's from ALLISON for the 1K/2K series trans. Only a few of the GEN4 TCM's can be tuned though as EFILIVE doesn't support full reading of the GEN4 TCM's do to the amount of info they have in them and how long the read time would be.
    1995 GMC 2500 SUBURBAN powered by 01 DURAMAX/ALLISON, little of this, a little of that,
    DIAMONDEYE 4" exhaust, CORSA muffler, AFE stage 1 dry filter, custom tuning by me, KENNEDY single pump and pump rub kit.

    The Allison 2000 OS is a standalone system, no engine data is sent to the trans.

    This only works on a 5speed.
