Tim,
thanks,
i agree that it can ring a little all the time too, but after a long
drive in warm weather it REALLY rings and lurches
clang-clang-clang-lurch-clang....etc
then the next day after cooling off it only rings if i shift poorly, but
when hot after the long drive there is just no way i can go into reverse
and backup without getting this kinda response from it.

it might be similar to asthma....you have it all the time, but when
certain pollens come out it can be really bad

later,
fred
