It doesn't have one. On the right side of the transmission is a fill plug(nut) you take out with the car running. You add fluid until it starts to come back out. Now it's full. Replace the plug before you turn off the car. It gets hot there,so be careful. At auto zone they have a hose with a shutoff on the screw end that will screw on to a plastic bottle of transmission fluid that works to fill it. You need the car on a lift so its level. You have to do this from under the car.
