help with my converter lockup

[custom 68]

History: I have a 2002 5.3 motor and 4l60e. The motor is stock and the tranny has a transgo kit and a trailblazer stall. Aftermarket harness to the Nelson tuned computer. This is a conversion in a 68 pickup.
The converter locks up in both 3rd and 4th. I can hear and feel the change in RPMs. When I let off the gas to coast at basically any speed the converter will unlock. As soon as I touch the gas it will lock again. Is this normal or atleast ok? I installed a new brake switch to “power” the lockup. The brake doesn’t unlock only when I let off the gas.
Thanks
Dave

your converter shouldnt be unloicking untill you slow down to the set speed in your PCM table.

but if it is set to unlock at a higher speed than what you are at then it will unlock on you..

this thing is running really really great I am not sure if I want to get it "fixed"
No it just didnt seem exactly right but I wasnt sure. I will investigate tonight.
I dont have any way to log what it is doing (yet) just going by the sounds and feel.
