Shuttering, vibration when TC locks up?

When converter locks up at 45 mph there is a shuttering, slight vibration until it fully locks up??? The only thing I have changed on my car recently is a new FAST 78 throttle body. Any help would be appreciated. Thanks

i had a shuttering problem with my tc, it would shudder when locked up under light throttle, i just replaced it with a new vig 3600 and the shudder has stopped plus the tranny feels smoother, could be the tcc, a lot of people have been having issues with theirs of late

I am no tuning guru but increase the duty cycle to 100 percent I think then see what happens PWM should be eliminated on all performance small diameter converters. Mechanically or other wise
