When I poor coolant into the radiator it emptys right away but I don't have any leaks
My car has an automatic transmission.

If you keep pouring in coolant and it is disappearing without any external leaks after two gallons of coolant then you have an engine problem or heater core is leaking into the a/c housing. Check inside car to see if any coolant is leaking on floor in front under dash. If none and no smell of coolant inside car then the engine head gaskets are leaking into the motor. Check to see if oil level is overfull and looks milky where oil and coolant is mixing? If it is mixing then you will need to have engine gaskets and head checked for leaks.
