MANUAL TRANSMISSION

THE MOST WANTED TRANSMISSION FOR

 YOUNG GENERATION !!! 😍😍

THE INTRO...

    A manual transmission requires the driver to operate the gear stick and clutch in order to change gears, unlike an automatic transmission or semi-automatic transmission, where one or both of these functions are automated. 

    Most manual transmissions for cars allow the driver to select any gear ratio at any time, for example shifting from 2nd to 4th gear, or 5th to 3rd gear. However, sequential manual transmissions, which are commonly used in motorcycles and racing cars, only allow the driver to select the next-higher or next-lower gear.

    In a vehicle with a manual transmission, the flywheel is attached to the engine’s crankshaft, therefore rotating at engine speed. A clutch sits between the flywheel and the transmission input shaft, controlling whether the transmission is connected to the engine or not connected to the engine. When the engine is running and the clutch is engaged, the flywheel spins the clutch plate and hence the transmission. 

    The design of most manual transmissions for cars is that gear ratios are selected by locking selected gear pairs to the output shaft inside the transmission. This is a fundamental difference compared with a typical hydraulic automatic transmission, which uses an epicyclic (planetary) design, and a hydraulic torque converter.

    Contemporary manual transmissions for cars typically use five or six forward gears ratios and one reverse gear, however, transmissions with between two and seven gears have been produced at times.

TYPES OF MANUAL TRANSMISSION 

Dual-Clutch

    This transmission uses two clutches, which can be wet or dry. One clutch operates the even gears (2, 4, and 6). The other clutch operates the odd gears (1, 3, 5, and reverse). Dual-clutch transmissions were common in older cars and are still found in modern race cars. A computer controls the clutch engagement and shifting, bridging the gap between a manual and automatic transmission.

Unsynchronized

    The first manual transmissions were unsynchronized, or “non-synchro.” They were also called rock crushers because drivers would grind the gears together trying to get them to mesh. Trucks used this type of transmission well into the early 1960s because these transmissions were very strong.

Synchronized/Constant Mesh

    Synchronized/constant-mesh transmissions keep the cluster gear, drive gear, and main shaft gears constantly moving. These types of transmission use pads to slow down the gears. This eliminates the need for double-clutching action.

Automated

    An automated transmission sometimes referred to as an AMT, is a manual transmission with a computer controlling the shifting and clutch. The AMT is used in heavy-duty trucks.

 

Single-Clutch

    Single-clutch is a manual transmission with the computer controlling the shifting and clutch. Shifting and clutch control can be electric, hydraulic, or electrohydraulic. The popularity of single-clutch transmissions started to fade as dual-clutches were able to handle increased torque.

BASIC MAINTENANCE 🔧🔨

👉 The transmission needs oil change typically every 20,000 to 40,000 kilometers depending on conditions and driving habits.

👉 Do not drive with the clutch unless you are starting on a hill.

👉 When decelerating, fully engage and disengage the clutch to downshift.

👉 Slight increase in engine RPM when engaging the clutch in the lower gear reduces shift shock throughout the drivetrain, and everything from the bushings to the clutch to the drivetrain lasts longer.

ADVANTAGES ✅

👍 Easier to maintain

👍 Doesn't require frequent oil changes

👍 Fuel efficient

👍 More control

👍 Cheaper price

DISADVANTAGES ❎

👍 Requires practice

👍 Difficult on hills

👍 Pain from the clutch

👍 Driver must coordinate clutch, gas, and shifting

👍 Lower resale value
