Hello, do you have a way to scan for codes?

Having to rev up the engine to engage reverse indicates there is a leak inside the transmission. By revving the engine you are increases transmission line pressure to engage the trans. It's possible the transmission can be going out and is causing your clunking noises as well.

initially while backing out of drive way it felt as if i hadn't fully released park brake. I put it in neutral and coasted backwards a few feet, same symptoms things weren't extreme at that point drove approx. 7 mi. by the time i returned home i determined vehicle not safe.
In other words the symptoms got worse during a short drive. Normal power in forward gears but some clunking sounds.
Almost felt like loose steering?

If you have the vehicle idling in park rock the steering from side to side. Does it make a clunking noise?

Sorry , I was gone s while.
I tried rocking the vehicle , no clunking sound.

It sounds like your concern is going to be internally inside the transmission.
