The internal atu in my 6500 has started to malfunction,I can do a tune and it reports success,but when I transmit the swr goes haywire,I do a retune and get success message again,then again as I transmit the swr meter goes way up again but my external swr/power meter reports everything's ok,is my internal atu failing?.

Are you sure it's the tuner? 
Sounds like when I had RF coming into the shack on the coax shield and making the tuner think it was HI SWR. 

Mix 31 and 43 Beads on the Coax took care of that for me before the coax comes into the house now no more fake SWR readings to the Auto Tuner. 

Also tune at the same power as your transmit SSB power to see if it does it, could also be a Antenna, Balun, or feed line problem that only shows up at higher power levels.

Change out the coax between the Radio and external SWR meter maybe you have a bad jumper.
