Since yours is a laft hand drive car, the gearbox filler plug is on the drivers side tunnel.
A good 20W50 will be enough. If the gearbox is noisy in the intermediate gears, eventually you will have to replace the bearings, at least from the layshaft. But it can go like this for ages.
Found it !
There was hardly any oil in it, I could pour almost a liter in it…
There is no difference in the noise, at least not much , so damage is already there
Second picture is with oil.
