2003 Transmisson slip.

Hi have a 2003 6.0 w/144k miles need help diagnosing the transmission. Owned for about 5k miles haven't had a problem, the truck was well kept and serviced.

It developed a slip I believe it to be the torque converter, what's your guys opinion? Posted two vids.

Weird thing the relay for the taillights started clicking when this problem developed. So I unplugged the batteries and the slipping went away for about 40 miles.

Thanks for the help
