6l80 silverado deceleration unlock time delay

2010 silverado 6.2l a6 4x4, tsp vvt 1.2 cam, circle d 3200 converter

i have 2 questions im trying to figure out

1.. any time i get a downshift on deceleration or on a no load downshift the tcc calls for unlock and it seems to have a several second 

time delay untill it relocks. is this adjustable with hpt? tow haul mode is there any way to adjust the engine braking? im mainly refering to when you touch the brake and it causes it to downshift.. i recently reprogramed my tcm to a 2011 os to resolve other isues but now my t/h engine braking does not seem to work
