Then I suspect that some other parts where changed starting with S# 97H*-00001, but a TSB wasn't generated for those changes, which created the need for the check ball to be added. This last update is actually for a noise shifting OUT of reverse, not shifting into reverse as the two previous ones are.
The ball can be added with the tranny in place. It goes into the valve body itself. The tranny I got is one of the ones that needs this ball and I have heard the noise coming out of reverse a few times.
