Good news and bad for P0719, good it's not the actual transmission.

Could be a short between the TCU and stop light switch (harness) or check fuse 16, if bad, then short is between fuse 16 and the stop light switch or bad switch. Also check the TCU harness to see if it is not loose or has poor connection.

Worst case is you need a new TCU.
