The whole radiator,you can’t get just the cooler.A new radiator is not that much money these days now.

Yes, the trans fluid does go through the radiator, there are lines inside the tank to cool the trans oil as it goes through them.

If you have trans fluid in the coolant you have a ruptured line and need to STOP DRIVING THE CAR IMMEDIATELY!

Once the trans line ruptured it not only allows trans oil into the cooling system but it allows coolant into the transmission and severe damage WILL occur. Basically the coolant gets hot and literally steams the friction material off the clutches in the trans.

When you change the radiator change the trans oil and flush the lines and system.
