I don't see anything particularly wrong

I see the car locking the torque converter to save slippage and reduce fuel economy (that's when you see the revs drop a bit)

The behaviour of the transmission depends on driver behaviour. Drive it hard and it will shift at higher RPMs as it recognises you are using more throttle and demanding more performance.

Drive it softly and gently, and it will shift at lower RPMs to enhance fuel economy and provide a smoother ride.
