There's no way this can be related to the valves, and very unlikely it's gearbox oil.
The gearbox and transfer case oils are seperate though, so you can't damage the transfer case by changing the gearbox oil.
They said they done it by opening the fuel pump in the back of the car with tester.
Carpet was put back like you can imagine and plastic clip broken and smell of fuel all around.
Was not present...
I do not trust but had no choice.
Why thinking of transfert case/ gearbox is because ( sorry repeating myself) while driving at 100km/h and put N and back to D it working normally again and then starts again. Also happening only when long distances made. I unfortunatly use it as daily car untill other solution...
I know i am newbie and not a mechanic at all. Just a guy that is curious and wants to understand more than i know about cars. This to try not to be scammed.
I do consider every advise especially from u as i saw you did help a lot of people.
Thanks for that.
