IT IS BAD 2020 !!!
First of all - hyundai central sent information to my dealer - this damage is due to user and they won't repair the car on warranty !!! They have some kind of "black box" in the gearbox and they have information that I damaged the gearbox by reducing the gears, rpm-s were critical 8200 (8k is max on tacho), speed was 67km/h and something happened to the gearbox......
My god - HOW I did it ? How to break rpm-s rotation limiter ? There is safety rpm-s cut off. On street and all dynos you can go max 6,8-7,1k rpm-s with hot engine.....
So I lost warranty on gearbox.....
Now I need to buy gearbox or repair this one on my cost.
Now looking for used gearbox. New gearbox is about 7900$ but I found few used for about 750$.
Year 2020.......my god 2020....... what will be next ? Earthquake directly under my car ?
