When you are unable to shift out of park, the interlock is not working. Check for a blown brake fuse or bad brake switch.
You cannot apply any direct power to the shift solenoids. They are controlled by the TCM and if the 'S' is blinking when moving, there should be some problem which you need to retrieve the DTC.
With the SCS bridged and ignition switch turned to on, count the number of blinks at the 'S' light and come back with the readings.
Long blinks = 10 whereas
short ones = 1.
