Final answer:

If fluid is leaking from around the automatic transmission pan, the most likely culprit is a faulty transmission pan gasket. To fix the issue, the transmission pan gasket should be replaced. It's important to note that if the rear seal of the transmission is also damaged, it may need to be replaced as well.

Explanation:

If fluid is leaking from around the automatic transmission pan, the most likely culprit is a faulty transmission pan gasket. The gasket forms a seal between the transmission pan and the transmission housing, and if it becomes worn or damaged, the transmission fluid can leak out.

To fix the issue, the transmission pan gasket should be replaced. This involves draining the transmission fluid, removing the transmission pan, cleaning the mating surfaces, and installing a new gasket. Once the new gasket is in place, the transmission pan can be reinstalled and the transmission fluid can be refilled to the appropriate level.

It's important to note that if the rear seal of the transmission is also damaged, it may need to be replaced as well. The rear seal is located at the back of the transmission and seals the driveshaft where it enters the transmission. However, the most common cause of a transmission fluid leak from the pan area is a faulty gasket.
