Since I have an auto torque values effect shifts and I have been keen to understand what the PCM thinks the torque is as desired shift times and trans pressure is calibrated using torque values.
I do admit it is pretty good as I have programmed the VSS changes how I like, but I do not understand when the torque values are used to determine shifts (ie D1108-D1110 & D0701-D0703).
Thanks,
