46RE ticks in all gears except reverse

So here's how it went this morning, cold, right off startup. Noisy as usual in park, quiet after a second or 2 in reverse, tick in neutral and all forward gears, but not as pronounced as park...quieter, almost sporadic, but still noticeable. Applying throttle pressure in evry gear but park stopped the tick, no effect in park regardless of rpm or how long I held TP on.
