Hello try this:-
Transmission fluid is clean
While lugging is occurring, I hit the brake pedal lightly; the "lugging" or "bucking" immediately stopped then Immediately returned when I released the brake, so I suspected my "Lock up" condition is less than perfect.
Here is the part that keeps me up nights! During this "lugging" at the 45 to 60 mph acceleration, my buddies on board computer reports the TCC signal is in fact active.
