They all make noise, but you could try to rebuild it. They make kits.
One thing i found by accident is that Mercon V transmission fluid for fords has made mine SILENT.
I had a leak and when i replaced a line didn't have the fluid i thought i had and used that, i just never got around to change it out because it is so quiet.
(My leak was too small to make the noise, about a pint every two-3 weeks. It had always made the noise before, and all my other jeeps.)
