| control: | stick shift | Automatic gear selector |
| The gear selector stick works to choose between the different forward gears of the gearbox as follows: 1st shift 1, 2nd gear 2, 3rd gear 3, …….. It continues depending on the number of gears and may reach 6 gears. Also, the neutral shift N, where the gears are not engaged. and a reverse gear shift, R, which requires pressure or pull on the stick so that it is not accidentally shifted while traveling forward. And often draws on the handle of the stick movement of the moves. | The shift position selector operates in the following order: hold position P, reverse position R, neutral position N, travel position D in which a number of moves are normally 3 to 4 and has now reached 8 gears, the second position is 2 or S for the movement forward so that The transmission does not go beyond the second gear, put the first 1or L of the forward motion so that the transmission does not go beyond the first gear. This is the order: left to right, top to bottom or clockwise) | |
| Parts difference: | – Friction clutch – Clutch pedal – mechanical or hydraulic links – spur gears , helical gears – Shafts – synchronizer mechanism – Lubricant oil – Grenade Roller bearings | – Torque converter – Planetary gear set – Clutches and brake belts – Clutches and bands – hydraulic valve body or electronic control unit – Module ECM, Electronic Control – Oil and lubricating oil – Fluid pump – Governor regulator Active cooler |
| Manual Transmission | Auto Transmission | |
| Advantages | – Saves fuel by 2-5 miles per gallon – The car in which it is installed is cheaper by 800 to 1200 dollars – Cheaper in maintenance – More widespread in Europe and the rest of the world – Significantly better acceleration – Higher performance – Giving more control from the driver over the performance of the car – Does not require an oil cooler – it weighs less than an automatic transmission – does not have an oil pump, which consumes a portion of the engine’s power. – More efficient to work There is no slip as in the torque converter – the driver can make the most of the engine’s power. – Fit for small cars as they usually use a small engine, self-transportation may reduce its speed. Better in mountainous and muddy roads in terms of control. The amount of torque required for the wheel can be controlled, and the engine can be used as a brake for the car in an effective way. | – Provides comfort for the driver – Comfortable and fast transportation – Easier to drive, as there are no 2 alternatives (gasoline and brakes) only. The left foot is not used while driving, and the hands are on the steering wheel most of the time, for better and safer control. Puts less load on the engine and transmission parts, so the cost of maintenance is lower for the service life of the vehicle. Less maintenance – there is no need to replace the clutch disc, which is worn out and needs to be replaced. – The most widespread in America, representing 84% of the cars sold in North America – Fit for disabled cars |
| Defects | Fatigue with handling the car in heavy traffic conditions, due to the need to press the clutch pedal and continuous manual transmission. – Needs to change the oil at a rate higher than the automatic gearbox – Eats more, especially the clutch – Needs skill and experience in handling – Difficulty starting the movement on the inside for beginners (some cars are equipped with a means of clinging to the insider) – The lack of demand in America, for example, finds it difficult in resale. It represents only 8-10% of car sales annually, but the situation is different in Europe and many countries. | – Higher fuel consumption 10% – The automatic transmission has an early shift that loses a large part of the maximum power 20% – The most expensive – Heavier weight – The cost of repair is higher – If the starter does not work, the car cannot be straightened by pushing the car and lifting the foot From the clutch pedal to straighten the engine by the wheel. (In this case, the car is powered by a cable connection to the battery, towed the car, or loaded onto a truck). In some countries, if a person obtains a driving license for cars with automatic transmission, he is not allowed to drive cars with manual transmission and vice versa. – Needs regular maintenance (filter change – oil – front and rear sofa) |
| the use | – Small cars (economic) – more widespread in European countries, and most countries of the world – first choice for young people – sports cars – most racing cars have a manual transmission. Heavy transport vehicles, as they bear the high torques to move the large load of the truck. | – Luxurious and expensive cars – The most widespread in the United States – The first choice in traffic congested areas – Most taxis in America – The first choice for older drivers |
