Good afternoon Gentlemen
The Pao was made in the Pike factory along with the Figaro.
The Micra, and Figaro both use Dextron III, as they run at quite a high temperature.
The gearbox number is written on a plate just left (ship's left) of the torque converter bell, and forward of the big round black cap.
On the Micra it is the RL3F01A gearbox, which has a torque converter lock, to improve fuel economy on a long drive.
The Figaro has the RN3F01A. Both have a capacity of 6 litres, but you can not drain the torque converter, which holds about 2 litres.
If you want to replace the oil in that, then you have to drain and refill at least 3 times. The old oil is good for preserving your fence panels though, specially when mixed with old engine oil. Anyone bring to vault the fence gets an oily shirt to boot.
I hope this helps.
