The driver of a semi-automatic will still have to change gears using a manual gearbox. The only thing is that the gearbox does not need you to press any clutch pedal because the electronics of the semiautomatic take care of the clutch by itself.

Because of this, the gearbox can accurately calculate the right moment for the gears to shift, allowing them to shift quickly and smoothly.

The only problem is that you may find yourself with a gearbox that doesn’t do its job as fast as you’d like. This would especially be the case if you are driving and then need to brake hard to slow down quickly.

Cons

• It requires more money to maintain a semi-auto than a manual.
• Repairing a semiautomatic is expensive. In fact, replacement would be cheaper.
• Semi-autos have a history of malfunctions and failures. There are many reasons why this could happen, and they may not even involve streaming directly.

Pros

• The driving experience is very smooth when changing gears.
• If the torque converters experience slippage, there will be no power loss. You also won’t experience this loss during manual shifts.
