Your vehicle may have a transmission leak due to a possible trans cooler line seal that is broken, a seal somewhere in the system may be dry rotted, or a breach in the system somewhere.
It may be a seal or gasket, something could be cracked. You might want to take it to a certified technician.

If your vehicle is leaking transmission fluid, you will need to have it looked at to find where the leak is located. It is better to have it checked out soon to avoid having a much larger problem later.
