Hello, someone has a tip on the following problem. Voyager Bj.99. The gearbox does not turn up! All driving ranges work, R,D,3,L. In P and N the engine can be started in this way the gear selector should be correct. The problem has occurred after gear oil and filter changes. In the Wekstatt manual what is set about modulating pressure. Could be the cause here? Maybe someone has a few tips.
