Transmission fluid can leak from many places. It could leak from the actual transmission itself, or any of the tubing that goes from the transmission to other parts of the car.
A transmission fluid leak means that the plug may need to be replace, or the seal or gasket may need to be replace. As it could be caused by a work seal, or gasket, or a loose plug.
Transmission fluid leak can be caused by couple of things. Most common being an worn out or broken seal. The transmission seals on most cars are made from rubber or metal. Seal is exposed to extreme temperature for years and the parts moving around them will eventually cause seals to fail resulting fluid leak. Faulty installation of a seal can also cause a leak. The another thing that can cause a leak is, if transmission case or pan is damaged due to low ground clearance.
