where is it located

The exact procedure is in the car is owners manual.

start the engine & let it run for about 20 min. on a flat surface ,under the transmission in the bottom of the pan is a large plug. in the center of the plug is another plug.a small T30 torx Will remove it . with the engine running remove the center plug. If u remove the large plug u will drain all the fluid. with the small plug removed & the temp of the trany fluid about 100 deg the fluid should drip from the hole. if not add 1/2 quart of mercon V at a time using a fluid pump until its full. Good luck
