Torque Converters: What Makes 'Em Tick? 

Great Video.... thank you very informative

Cheers!

Great video Dave! I recently received and installed a TC that showed up at my door with some pretty severe box damage, as if it was tossed around roughly by a disgruntled shipping employee. The TC looked fine, but I experienced a mild vibration between 2200 rpm and 2500 rpm. So I clocked the TC to the next bolt hole over and it changed where the vibration starts. Now the vibration starts at 2400 rpm through about 2600 tpm. Would you think that the TC got damaged from it being thrown around or it's just not properly balanced? Your opinion would be greatly appreciated!
