MY TRANSMISSION FLUID HOSES ARE LEAKING UNDERNEATH RADIATOR AT THE CRIMP IN THE END OF THE HOSE DOES THE ENTIRE HOSE NEED TO BE REPLACED OR JUST THE METAL END?

If it was made too tight, then that eplains the leak. You may be able to just cut off the end and be ok if the is enough left. However, if it is my car and intend to drive it I would just get a new hose alltogether. They are relatively cheap and it ensures that it was not a faulty hose in the fisrt place.
