Just think, all that's between your auto-transmission oil and the engine coolant is some very thin aluminum bent into complex shapes inside the intercooler
They do fail!

You are correct. Years ago, the radiators and heater cores were brass or 
copper. They could be repaired by soldering if the damage was not too extensive.
These days, the manufacturers are more concerned with less weight and cost, so 
they use an aluminum core with plastic for the side tanks that are crimped on 
with a rubber gasket in between.

Plastic would not conduct the heat from the anti freeze into the air passing 
around/through it.

I don’t think this is correct.
  Every one I’ve ever seen is now aluminum.

  some cars have either all-plastic radiators, or, maybe
  plastic heater cores for the A/C. Maybe that would remove
  the issues of metal ions from the heat-exchanger.
  Undoubtedly less efficient at removing heat from the water
  than metal, but size cures a lot of ills.
