What is the problem when the car leaks transmission fluid and starts but won go anywhere?
The transmission needs fluid to propel the car. If there’s no fluid, you’re going nowhere. Fill it up, and find the source of the leak. It could be a transmission seal, or maybe it’s as simple as a damaged line from the rad. Don’t try to move the vehicle at all until the transmission is full of fluid. You could burn out the transmission, causing a very costly repair.
