Hello, our car was fitted with a used automatic transmission at the Volvo partner this winter, after I was stranded with gear damage. Yesterday then the key experience: With every gear change there was no jerk, but blows, whereby the car shook under strong vibrations. That got better then with the time, but it did not disappear. After the work arrived at home, the same thing: stopped, driving stage R inserted, *Rums* and the car rüt If I should stay down again, the Volvo will finally fly out with us. Greetings 850 Limo
