4r100 TC lockup question

Shoudn't the tourque converter unlock when the break pedal is depresed? I can see the TC lock up and if I hit the overdrive off it will kick down into 3rd and them lock the converter back in, but going down the raod and hitting the break ever so softly the RPM does not change so tells me the TQ is not unlocking that way. Any thought??????

Found out, that with my PCM code it should not unlock with the brake. Thanks for all that looked
