I am going to need to change the hoses that run the tranmission fluid to my radiator real soon as they show signs of cracking. Does anyone know what type of hose I need to use for this? Is this a specific/dealer part of can I use heater hose?

It is special high-temperature, high-pressure line. Go to a parts store and ask for transmission cooler line.

I just bought some last week for mine. They are pre-molded like the radiator hoses. Don't know the cost as they were bought with other parts.
