    COMPONENT DESCRIPTION
    These circuit lines are used to control the smooth shifting up and down of A/T during the hard acceleration/ deceleration. Voltage signals are exchanged between ECM and A/T control unit.
    what did the diag you had tell the tech who chcked it?? he should have an answer for you on the failure.
    if you had a free code pull, then a full diag is required to see why there is no communication between the tcm and the pcm.
