The gear shifts in a semi-automatic transmission without DSG or a semi-automatic transmission with a torque converter can be less smooth and slower compared to a DSG transmission. This is because DSG transmissions use dual clutches to pre-select the next gear, resulting in quicker and smoother gear shifts. On the other hand, semi-automatic transmissions with a torque converter may experience more noticeable lag and jerky shifts, especially during aggressive driving or quick acceleration. However, advancements in technology have improved the performance of semi-automatic transmissions with torque converters, making them more refined and responsive than in the past. **
