Is type F automatic transmission fluid the correct to use in a 1973 Dodge Dart 318?

No, Type F automatic transmission fluid is not correct for a 1973 Dodge Dart with a 318 engine. Cars from that era generally used ATF that's now considered obsolete. You'll need to consult your owner's manual (if you have it) or a reputable repair manual specific to that year and model Dodge Dart to determine the correct fluid type. The transmission type (e.g., 727 TorqueFlite, 904) will help determine the proper fluid specification. Using the incorrect fluid can severely damage your transmission.
