Hello and that I had a small gearbox problem about 4 days ago. And I was traveling with approx. 220kmh on the highway as plötzlch was standing in the BC “Automatic gearbox”. He then slid down briefly and then was on approx. 6900upm and then immediately up again on approx. 5200upm. then I am off the gas and he then ran at approx. 100kmh on approx. 3800upm and did not want to power up anymore??? I then drove back home so around the 40kilometers. However, he already after 20KM of all ine the speed again runtrgeregelt at 100kmh on approx. 2500upm. When I was home I turned it off and started again and it’s all normal, but I don’t dare to do a kickdown anymore. The gearbox is still the first and is now 13 years old (247500km) and has never had an oil/filter change. Do you still think that’s worth doing that, or is it probably flattened soon anyway, because then I can save myself that and immediately steal another. There are just so many different opinions about the oil change in the AR35, some say yes is better the other NO just after that everything is shit
