It was leaking there at the little shaft under the dobble lipp seal.
This little shaft turns around if the motor rpm goes higher, then there Comes some oil out...
But you can hold it also with a gripper.

I put some 2K glue on it, from this moment it was dense and there was no problem of different feeling with the transmission.

But i have now anymore the problem with my break on this side, i changed the brake pads.

It wasnt much better.

Now i think it is getting to hot, i will try to instal a cooling fan, like they are on the newer models.
