    Shift Inertia Factor Profile CT Downshift

    Hello Everyone,

    Can someone tell me where/what the underlying table(s) are for the 6L80E shift inertia factor profile CT downshift? See attached pic.

    I believe this is going to affect closed throttle downshift. Not 100% certain though. But I see negative torque on the table.

    Thanks. I am trying to figure out which tables the numbers are referencing.

    its not referencing any table
    its the actual torque factor

    1 is very soft shift
    9 is very firm shift

    those tables dictate the feel of the shift

    they are used in conjunction with shift pressures and shift timing
