I'm having some fun, symptoms are taking a while (and a few clunks) to move from Drive to Neutral, occasionally not selecting reverse (flashing spanner on display), and code 19143 "Unexpected / Implausible mechanical Gear Disengagement : P2711" logged.

I'm guessing this is a mechatronic issue, not a gearbox issue. I'm intending removing mechatronic unit and sending it off for repair as first throw of the dice. Does anyone know if the mechatronic unit can be removed without removing the whole gearbox? I've watched youtube videos of this happening on other cars, but it sure looks tight on an Alhambra!
