L322 Gearbox problem

Good morning
Here are the answers to the comments I received, thank's for them.
- LiquiMoly TopTec 1800 oil, the reason for that is that I have read on several websites that it fits well in that gearbox and that the shifts go even smoother, and the other reason is that it is difficult to get ZF oils in Finland.
"- Transfer of the old gearbox control device to the gearbox arrived from (I mistakenly wrote Holland) Netherlands" in the list meant replacing the ECU.
Arto

The Range Rover is on the road again, the renovation was delayed by getting the oil cooler to Finland, due to the harbor stevedores' strike.
According to the repair shop, the gearbox had clearly been removed from the car, so some kind of fraud is suspected in the sale of the car, but it is unlikely that the car shop where the car was exchanged could have known about it.
About the costs, so much so that the car dealership paid for the gearbox and I paid for the replacement work.
Now the gearbox seems to work as it should and I really hope it continues to work like this.
