Forgot this part. I did not know I had a leak until the pump started making noise. I added fluid thinking that with about 250,000 miles it was NORMAL to use some. But then I soon needed to add more when the noise came back. So at least twice I ran low on fluid with the pump starving for fluid. I am thinking I might have damaged the pump internally running on low oil. This is why I was thinking of a reman pump to cover myself if I have damaged internal moving parts. Also I am very confident I have been using ps fluid. But maybe changing to synthetic fluid might help or solve problem (from your referenced thread).
Thanks again for your help. T
