Ray,

I wonder if the sounds coming when you were in 5th gear could have been due to low fluid level in the transmission? You drained and filled. The old stuff looked fine. You filled with good stuff. I assume there was good stuff in it before. If it was low and is now full, maybe that (low fluid level)would cause the symptom and provide the cure (proper fluid level).

Could be, Jack. Unfortunately, the old oil went straight to a drain pan with a lot of other gunk. Couldn't really measure. Old tranny oil looked almost exactly like the new stuff I was putting in (liquid gold).
Not sure if groaning is a known symptom of low tranny fluid in a Tremec. Maybe the tranny gurus can verify? I was pretty convinced it was the rear end judging from the directional "feel"; especially since I've had the top up until last Friday...
