The transmission in my 2022 GMC Savana experiences severe harsh shifting during normal driving conditions. The issue is most noticeable between 1st–2nd gear and 2nd–3rd gear, with 2nd gear being especially problematic. The vehicle jerks and slams aggressively into gear during acceleration, causing unstable driving behavior and hesitation. In addition, when coming to a complete stop, the vehicle jerks forward unexpectedly. When accelerating again from a stop, the transmission jerks hard once more before shifting. This behavior occurs repeatedly during everyday driving and creates a safety concern, especially in traffic, intersections, parking areas, and while merging onto highways. The condition has progressively become worse over time and the vehicle currently has approximately 71,000 miles. The sudden shifting and jerking behavior affects vehicle control and creates concern for the safety of the driver, passengers, and surrounding traffic. No warning lights were present at the time of the issue. The problem appears to be related to the transmission/powertrain system. I also became aware that similar transmission and harsh shifting problems have been reported by other owners of the same make and model vehicle, despite my VIN currently not being included in any recall while others had a transmission recall
