    E38 p0705 trans range code not there to turn off

    I have a 2007 yukon engine and trans in a swap. There is no trans range switch in the harness or on the trans. It is throwing a p0705 code, but I do not see the DTC to beable to turn it off. Is it hidden somewhere? How can I turn off the range switch and/or code?

    I am on 2.24.848
    ECM is a e38
    TCM is a t42

    Unfortunately we do not yet have access to T42 DTCs. You will have to wire up the switch or deal with the code.
    In a recent e-mail I was told they plan to add it in 2.26 so it could be a while since 2.25 isn't even out yet.

    Would also be nice to have access to the steady state pressure tables..

    The P0705 code is under Trans Diagnostics in 2.25
