Temporarily replaced relay with a 20/30 and overdrive is again working crisply. I've ordered a dozen 60 amp per HRL'S recommendation and will install a single 60 amp in the place of the 20/30 when they come in.
So for the record the symptom was as if the blocker ring had lost friction and wouldn't engage overdrive and symptom #2, failure/intermittent relay. Cheap and easy solution, thanks for the help.
Worth keeping an extra relay in my on board fix-kit.
