I have 2018 grande having auto transmission. I am not sure whether its supposed to be like this or not but in the morning or when the engine is cool, the car would rev up instead of shifting gears until the rev reaches above 2. Then the engine heats up and it works as expected. I didn't pay any attention to it when I got this car. Perhaps it was not doing like this then. I changed the transmission oil few days ago, its still doing this. Is this an issue or is it standard behavior of cvt / grande?
