Good evening love community, like so many users, I register here out of desperation with regard to my Volvo C70 2.4T automatic (BJ. 2001) with Aisin AW55-50SN transmission. The following scenario is available. I purchased the car a month ago used, the transmission turned off fine, if one takes the usual wear at the mileage of 250,000 kilometers, but at warm temperature and between the third and fourth gears somewhat rough. Therefore, because I am through the my workshop was commissioned to change gear oil, where part of the oil should be changed and also the B4 cover update should be installed. Both have now been done. At the evening pickup, I was told at the handover that the gear would run a little bit bigger, so I thought that it might have to adapt a little bit more and that this would only be marginally noticeable. At the ride, however, the big shock came, because from the second to the third gear and from the third to the fourth gear, the gearbox practically does not switch or only with a fixed and far delayed jerk, before the engine wakes up with the speed and generates no power transmission, as if I were giving full throttle at N. This had brought me smoothly into a dangerous situation during the ride. I then carefully drove the short distance home, as the workshop was already running. I have now searched the internet for a variety of reasons for these symptoms, but found nothing. Finally, when I was in cold condition, I measured the gear oil level and got a terror, because this is far above the necessary brand. Of course, I will go to the workshop tomorrow, my question is nevertheless, can it be due to the too high oil level? Must something be new from Volvo di I thank you in advance for possible help.
