My car has an automatic transmission.

The transmission requires the cooling system to be working correctly to keep it cool. If you have the cooling system pressure tested and locate the coolant leak and get it repaired. You may have a water pump leaking. Once the cooling system is fixed and transmission fluid level checked to make sure it is not overfilled or underfilled. Have area cleaned and road test to see if transmission or coolant is still leaking.
