Today my beloved Volvo gave up. He had started to switch the last days late from the first to the 2nd course. Especially when he was cold. Then everything was ok again. Then he jumped into the emergency run with a flashing famous arrow. I already thought about changing the gear oil. It still looks a bit bright but you can also find small black particles in it. Today the Volvo suddenly had no drive during the ride at approx. 80 km/h. Rolling out let the same problem start again after a while. He did not go from the spot anymore only the speedometer went up like idle. Then it did not go back again. The drive passed quite slowly when driving slowly until it pulled nothing at all. Now I left the Volvo there first. What do you mean it is a gear oil change still value or is it too late.
