If you find yourself with a transmission fluid leak, there are a few things you can do to fix it yourself. First, stop the car and put it in the park so the wheels are not turning. Then, find the transmission fluid leak and look for a hole in the metal where the fluid is coming out. If you can’t find the leak, you can use a flashlight to look through the hole and see if you can spot it. If you still can’t find the leak, take the car to a repair shop to have them find it for you.
