Volvo S60 automatic transmission issue on Volvo S60

Some Volvo S60 owners report experiencing automatic transmission issues, including slipping shifts when the air conditioning is running, constant shifting jerks, and hard shifts. These problems can lead to long intervals between gears, loss of transmission performance, and the illumination of the check engine light. Specific concerns also include slipping during the transition from 1st to 2nd gear, which can cause the engine to rev excessively and create a potentially dangerous driving situation. Additionally, owners have noted hard shifting into second gear, bevel gear noise, and overall transmission performance issues. It is recommended that these problems be addressed promptly to prevent further damage, with potential solutions such as software updates, fluid checks, and transmission fluid flushes. However, some repair attempts by Volvo dealerships, including software updates, may not always resolve the issues effectively. Comprehensive guides are available to assist owners of Volvo S60 models from 2002 to 2009 in troubleshooting and resolving these automatic transmission problems.
