A: You need to have the cooling system checked...

You need to have the cooling system checked to see if there is combustion gases getting in the cooling system, causing it to get hotter than it should. Since you have overheating problems you may have a blown head gasket which would explain the overheating issue. Make sure you topped off your transmission fluid also after the radiator replacement if the transmission cooler is in the radiator. If not, the transmission would be low on fluid and may run hotter than normal. If you need help with these checks, contact a certified mechanic, like one from YourMechanic, to help you diagnose your overheating issue and help you fix it accordingly.
