Torque Converter in a 904

New build with a rebuilt torque converter through a local shop who the guy is a MOPAR guy. He has done the last 4 for me. Been driving the Valiant on local roads for a few miles less than 35MPH. First real drive. Hit 55 and heard this screeching. Pulled over checked fluids, all good. Turned around back home no noise. Went for another ride and pulled over after 3 miles and loud racket like bearing or something. Back home. On the lift sounded like the TC bolts loose hitting the shield. checked everything and nothing loose. It sound like a screaching, grinding sound. It is working and shifting fine. Can a TC make that sort of racket?

Note it make this noise in park and just running now.
