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

BRAKE SYSTEM

  THE BRAKE SYSTEM What is a brake system ?       A brake is a mechanical device designed to restrain motion by absorbing energy from a moving system usually by the means of friction. It is used to slow or stop a moving vehicle, wheels, axle, etc. The braking system is a complication device with a lot of parts, but its working seems very easy. After all, pressing a single pedal will activate all brakes on the four wheels. The slowing down is achieved by hydraulic fluid, which is often bleed to get the best performance of the breaking. Air is not allowed in the system else the component won’t work well.      Most brakes are designed to use friction between two surfaces, they’re pressed to convert the kinetic energy of the moving object into heat. Though several methods of energy conversion are now employed. In an automobile, friction brakes store braking heat in the drum brake or disc brake which then gradually converts into the air.  ...

4G63T ENGINE

THE GLORY MITSUBISHI’S 4G63 ENGINE: SPECS, POWER & RELIABILITY Popularly dubbed as the 2JZ of the 4-cylinder world, the 4G63 is a real hoot to have under the hood. The fact that it was built to meet the standards of the World Rally Championships explains why it can be tuned to make over 1000 hp. History of Mitsubishi’s 4G63 Engine The 4G63 engine was first introduced in the 1980 Mitsubishi Galant model as a replacement for the 4G52 engine. It’s part of the Mitsubishi Sirius 4G6 engine family; a series of inline-four high-performance engines that were produced by Mitsubishi in the late 70s. In fact, when Mitsubishi sought to compete in the FIA World Rally Championship, it introduced the turbocharged version of the 4G63 engine in the Galant VR-4, Lancer Evolution, Lancer EX 2000 Turbo, and Carisma GT. At the peak of its glory, the Mitsubishi Lancer Evolution III fitted with a turbocharged 4G63 engine dominated the World Rally Championship by winning four consecutive titles. 4G63 En...

MOTOR OIL (ENGINE OIL)

  A guide for you to know about motor oil.  In this blog you will get to know what is the motor oil does means to you. Here’s what we’ll cover: What is motor oil? What is in motor oil? What must a motor oil do? What is viscosity? SAE viscosity grades (oil weights) What is motor oil?  Motor oil is one of the most important factors in your engine’s performance and longevity. Put simply,  it’s the lubricant that prevents all those metal parts from tearing each other apart or welding themselves together  into the world’s coolest boat anchor. It reduces friction and heat while helping keep your engine clean. Without motor oil, your engine would destroy itself in a matter of seconds. What is in motor oil? Motor oil contains two fundamental components:  base oils  and  additives . The two work in tandem to produce the final product you put in your engine. Think of coffee as an analogy – the base oil is the water and the additive package are the co...
