Different types of transmissions include:
1. Manual Transmission: Requires the driver to manually shift gears.
2. Automatic Transmission: Automatically changes gears without driver intervention.
3. Continuously Variable Transmission (CVT): Provides a seamless range of gear ratios.
4. Semi-Automatic & Dual-Clutch Transmissions: Blend manual & automatic features, allowing manual shifts without a clutch pedal.
