Re: '52 ultramatic clacking?

In early Ultras, at certain speeds the pump selector valve would shuttle and create a sort of rapid clacking sound. They solved this (and saved a lot of money) by changing to two small spring steel check valves. See the April 52 Service Counselor. If the trans is otherwise working normally, I'd give this a go.
