Our 2015 Silverado 1500 has stuttering/ hesitation when accelerating, when turning on to a street you can not get up to speed quick enough it acts like there is something hold it back. We have replaced the spark plug and wire and all the coil packs. The voltage meter on the truck keep fluctuating so we replaced the alternator and the battery and that did nothing and kept fluctuating so we got another alternator and another and another and another. . So 5 alternators later and still no fix. But the hard shifting is the main concern. Because when you are driving trying to get into another lane the truck with just start hesitating and jerking until it launches into gear. 1st gear going into 2nd gear the truck will shift extremely hard and 2nd going into 3rd feels like you are galloping until it finally engages. The computer has been replaced and reprogrammed with all updates by and ase certified mechanic. Also did a transmission fluid flush and changed. No service light. Just baffled with all these complaints about transmission why nothing is down. It is a serious safety issue.
