What are the types of manual transmissions?

Manual transmissions can be divided into the following types: 1. Manual Transmission (MT): Also known as manual gearbox, it requires manually shifting the gear lever to change the gear engagement inside the transmission, altering the gear ratio to achieve speed variation. 2. Automatic Transmission (AT): Utilizes planetary gear mechanisms for shifting, automatically adjusting gears based on throttle pedal position and vehicle speed changes. 3. Tiptronic Transmission: A manual/automatic integrated transmission that allows free switching between manual and automatic modes, automatically adjusting engine speed and gear position while offering the driving pleasure of a manual transmission and the convenience of an automatic transmission.
Manual transmissions mainly come in several types: sliding mesh, constant mesh, and synchromesh. The sliding mesh type, where gears directly slide into engagement (commonly seen in older vehicles), is prone to gear grinding or loud noises during shifting—I've encountered this while repairing cars, requiring precise RPM matching. Constant mesh, the modern mainstream type, has fixed gears and uses shift forks to select connections, making operation slightly easier. Synchromesh transmissions, like the one in my car, feature synchronizer rings that match gear speeds before engagement, enabling smooth and silent shifts—even worry-free driving in the rain. A few specialized vehicles use planetary gear manual transmissions, though they're rarely practical. The core appeal of manual transmissions lies in offering drivers direct control over the driving experience.
I drive a manual transmission car myself, and the experience can be categorized into several types. The sliding type, found in older models, requires more effort to shift gears on rural roads, needing a forceful motion to engage. The constant mesh type, commonly used now, requires fine-tuning of the RPM for smooth shifting at high speeds. The latest synchronizer type allows gears to engage with just a gentle push of the lever, making traffic jams less frustrating. Different types of shifting feel distinct and affect the driving mood. Driving a new car with a synchronized gearbox feels as smooth as gliding, and the joy of manual driving lies in the fingertip control.
