Yes, any auxillary cooler is better than none because heat is your transmission's enemy.
FRPP offers a little kit for the Mustang for about $100. It is pricey compared to the larger coolers by Hayden and B&M but all the necessary bits and pieces come with it, right down to the nylon zip-ties.
FWIW, a stacked plate cooler is preferred over the finned tube type cooler.
