Get some clean cardboard to put under the suspected area of the leak. That way you will be able to pinpoint the drip area and may help identify what is leaking.
Leaks are tough to pinpoint because of gravity. They travel down but they also travel with the air flow in the engine bay and under the vehicle. So where it drips to the ground can be misleading. You may have to look forward and up higher.
To determine what us leaking it will depend on color and feel. Engine oil is usually brown, manual trans and gearbox fluid is sticky. Auto trans and transfer case is pink.
