Saturn Vue RPMs pulse and vehicle surges between 25 and 45 mph, possible torque converter issue on Saturn Vue

Some Saturn Vue owners report experiencing pulsing RPMs and surging between 25 and 45 mph, which may indicate problems with the torque converter. These issues can stem from various factors, including bad transmission fluid, worn clutches, bad seals, or loose bolts. Symptoms of a faulty torque converter often include vibrations, excessive RPMs while driving on the highway, and slipping during operation. Additionally, owners have noted that the torque converter's failure to connect and disconnect the engine from the transmission can lead to torque converter shudder. Some have also reported a torque converter whine when the vehicle is stationary with the transmission in DRIVE or REVERSE, with the noise intensifying as engine RPMs increase. It is recommended that owners experiencing these symptoms have their Saturn Vue inspected by a qualified mechanic to diagnose and resolve any potential torque converter issues.
