Hello!
This is a very interresting problem you have here. It sounds like the symtpoms one would get from a clogged filter, but hopefully your shop replaced this when they replaced the oil. Normally one would diagnose such a problem by counting the number of activations for current drive on this valve that you have mentioned, there is a block for it in vagcom. I don't know, seeing as this is a problem I've never heard of before, is it possible that your TCU could have been harmed in the process of repairing it? It is an unofficial fix, the only approved method of fixing this problem is a new TCU. And yes, it has two clutches indeed. One for reverse and one for fwd.

Hey,
I got reply from repairshop with this same message and they said that clutch is defective. Because as you can see in the video when putting in D gear there is huge clutch value of 639.0Nm and backwards only 36.0Nm. Repairing starts at 1300€ yippeey. Bought the car and got to drive it only 200km..

This is very unfortunate, but the torque of your engine is unfortunately a bit high for this gearbox and a lot of the biggger engines develop similar problems.
However, I find it strange that it would suddenly malfunction like this, in all previous cases there is gear slipping, usually for years. It will be indicated by the jumping of the RPM needle in the area 1300-2000. The way I see it, the only way you could have truly broken the actual clutch is that if the pressure release valve did not actuate properly and thus allowed too much force on your clutch. It's supposed to be pretty fool-proof, reducing power output when needed. The manual even quotes that it's "nearly impossible to overload the clutch". You say that you read 626Nm on the clutch, this is over twice of your engine's maximum output. So there's definitely something fishy going on here.

Yeah I have read that too that gearbox will "disconnect" tha gas and you cant press it or it wont reply.
This yes happens but only when the engine is cold and only in P it discnnects gas. But gearbox will overheat i think but it goes over 95. And you can smell little bit oil..
Thank you really much for you answers! I would be really happy if I get it driving..

Okay, so, it overhats and you can smell oil. This is definitely not normal. It is then clearly creating a lot of friction which heats the oil. So yeah, ok. Maybe the engagement of the clutch is not working correctly. But as of the cause of it.. it's too difficult for me to say, this is a very complicated box.
