I am having such weird problems with my 09G transmissions.
I know they are known for their valve body issues but also that fluid changes sometimes help.

I have drained and added fluid now a few times. The issue used to be 1-2 and 3-4.
However, they are perfectly fine now and the issue is 2-3 and delayed reverse.

The problems only occur after driving the car for around an hour or so. When it is cold there is no issue.

When filling I have up on 4 jack stands and it seems to be level.

Are there certain symptoms if the car doesn't have enough fluid or too much (incase it isn't 100% level when I am checking) ?

Once again - only has these symptoms when driving for a long time.
