Although I agree that it is unlikely for those dips to be real, I think it is too early to say what is and what is not real at this point. Who knows, maybe the issue I brought up with clutch slippage/engagement is plausible since things are happening so fast in the D3 shift, and maybe those oscillations that occur after the interval you have marked as "the shift" are artifacts of the engagement process as the clutch loses and regains traction. Unlikely but not impossible.
