Ford Edge 6f50 Transmission Question

Hello Ford Geniuses,
I am having trouble with my wife's 2008 Edge FWD and could use your knowledge as I always find it useful.

The vehicle has exhibited the "reverse clunk" since we bought it 2 years ago at 77,000 miles. I had the fluid changed at a ford dealer and they produced a dark brownish purple sample and shook their heads. Last summer, on a hot day, my wife experienced the wrench light and I pulled an OSS code with my scantool. I replaced both OSS and TSS sensors and, of course, replaced fluid. Now at 100,000 miles, transcolor is a beautiful pink, but when the vehicle gets to operating temp, I get the reverse clunk when shifting from Drive to Reverse. If I shift Drive to Neutral and weight 3 seconds before shifting to Reverse, clunk is not noticeable. Additionally, I am recently noticing firmer shifts between gears, sometimes when downshifting. I suspect solenoid valve body also called TCM (trans control module). Has anyone else experienced this problem with this trans? Any advice?
