Remember to always prioritize safety and seek professional help if Hi everyone, I got a 2010 5. As a result, the transmission will wear even faster as the fluid is not protecting the internals. When reaching a nominal speed and engine RPM the convertor comes on and locks the convertor forming a slip free drive. These issues disrupt power transfer from the engine to the wheels. Determine if the RPM jump happens during acceleration, while maintaining a constant speed, or only during a gear change, as this narrows the possible causes to the engine management system or the transmission. Addressing the problem early can save you from expensive transmission repairs. There can be faults with some sensors as well. Thanks in advance.
