hello, I have an omega a 2,6 cd diamond automatic until recently the car ran without propleme also the automatic switched perfectly!! unfortunately the engine had to be replaced since it came to very strong smoke development. we used in the car again a 2,6 which also wonderfully clapped I have to say that the motor comes from a car with switch gear after 50km drive the automatic started spinning temporarily the first gear does not go in or the s starts to b left when pressing the kickdown. we couldn’t make a rhyme from where or why that came now especially because the automatic before did not make a propleme now well we decided to change the gearbox at first it had the appearance that it had brought something but after 40km I had the same proplem again. I’ve already made myself smart about what that can be but so far I’m not going any further because I can’t get the old engine anymore Since he went straight to the scrap I finally got as help: you had to get out how many teeth were on the V-belt disc (below the crankshaft) of the original motor (unless it was rebuilt) and compare them with the number of teeth on the new disc. Furthermore, the sensor that hangs under the teeth should have about the same distance to the pinion and have about the same appearance. who can help me there further or who drives still a n omega a 2,6 automatic which can count for a short time the number of teeth so that I can check them with my times. there are also other ideas that could help me in advance thank you for the help
