This is confusing! It sounds like your torque converter is unlocked before you release the accelerator and then it locks! This is really the only way you'd get significant engine braking in my opinion and the only way you'd get a noticeable "lurch". It seems exactly opposite to what I observe on my truck.

Well......

I just drove my truck again and i didn't notice it at all. I have put about 55 miles on my truck since i reprogrammed it back to stock.

I have chocked it up to relearning.

I hope i am right......
