Pontiac Solstice hard stop during downshifting, codes need to be reset on Pontiac Solstice

Some Pontiac Solstice owners report experiencing hard stops during downshifting, which may be linked to inadequate or dirty transmission fluid levels. These issues can lead to shifting problems if the transmission components, such as solenoids and sensors, show signs of damage or wear. Additionally, some owners find that resetting error codes using an OBD-II scanner can help alleviate transmission-related issues, but it is crucial to perform a drive cycle afterward to allow the vehicle's computer to relearn the transmission settings. Addressing these underlying problems is essential to prevent future transmission issues.
