Hello together. I drive a Peugeot Traveller Year of manufacture 2019 with 177 hp diesel engine and eat8 automatic gearbox especially at highway rides approx. 120 to 140 kmh light mountain if you want to demand a little power and switch the gearbox down from the eighth to the seventh gear I get following error codes p0893 and p 0741. Then the vehicle goes into the emergency run and I have to restart the engine to eliminate the error so that I can continue driving and then arises i same driving conditions and unfortunately the problem often prevails on the highway again and again. The transmission oil has been changed several times without a change someone can give me a tip on what this could be
