SCT/Trans Question

[WOOL-PULLER]

I dont know if i asked this question or not but has anyone else noticed this?
When i am driving above 40mph and let off the accelerator i feel/hear a vibration in the floorboard until it hits 40mph and under. at 40 (probably 44or 45mph actually, speedos off) you can feel something disengage and its smooth down to zero. I didnt think i felt this with the first sct program i ran when i first got the truck.
i just had the new tune put in and its still there. i thought this might clear it up.
the new tune does seem to shift better but i dont think it has the power the previous tune did.

is the torque converter locked up maybe?

Watch your RPM's. Your tourgue converter stays locked up untill lower speeds. I'm thinking to help maintian a smoother cost down instead of just loosing all power if power is needed. I notice kinda the same thing.

Call you SCT tunner and ask them.

i think its the convertor but i dont think the vibe i feel is normal. maybe some other people on here can chime in.
