Ok, this looks like the TCC but not is not completly gone. That happened to me once on my 93 Z-34 4t60e. I had to replace the tranny beause other issues and that stopped happening. Try adding high friction additives to the tranny to get a little more life out of it. But looks like it will die eventually(not in a short while, but in a while). What are U experiencing is a shifting problem do to a lack of enough pressure for the clutches to engage properly. Get the tranny rebuilt or look for the fricion adding additive. Ols school would add 1 cap of Wagner dot3 to the tranny oil, this will help the clutches engage better.
