Hello friends, I did not want to shoot this video willingly, but it is really important to reveal such people and raise awareness of people like this. That's why they put a stone to the bread of people who love their jobs and become professors in their jobs. I took it from our uncle to listen to him, he will tell his problem and you will listen. Not us, but our customer. Our vehicle is a vehicle with Opel Astra j 1.6 XER engine and 6t40 fully automatic transmission. The vehicle was constantly boiling water, also the cylinder head was removed twice, and it was made by sandpaper without giving the grinder to the grinder. Although they solved this problem themselves, they could not solve the problem. Let's come to another scandal, what is this, first of all, they thought that the fault of our vehicle, whose water radiator exploded, was caused by the oil cooler, and they would change the oil cooler and send the customer, but we will see together in the video where the transmission oil is mixed in the water. You will see that our vehicle, which has a 6t40 fully automatic transmission, has a complete transmission overhaul. Do not trust people who say that the transmission oil does not change in such fully automatic transmissions, first change the automatic transmission oil of your vehicle every 80,000 kilometers. How to understand the transmission failure in our video. We tried to address what are the chronic problems of automatic transmission, problems such as oil leakage in automatic transmissions and automatic transmission oil change. Automatic transmission repair should be done by people who are professional and good at their job, this is definitely very important. Automatic transmission repair is a very delicate job.
