Another key decision you have to make when buying a car is what type of transmission to get. Modern vehicles come in two different transmission types — automatic or manual.
In a manual transmission, the driver is responsible for shifting the gears, while in a vehicle with an automatic transmission, the car does the shifting for you.
So the question becomes, to shift or not to shift? One of the most complicated components in your vehicle, the transmission is a metal case that houses a series of gears — which explains its nickname of gearbox. The transmission takes power from the engine and delivers it to the wheels to help power your vehicle. It is responsible for making sure the right amount of power goes to the wheels so it can operate at a given speed.
When you take off from a dead stop, your vehicle uses a lower gear ratio to get the car moving using more power and less speed. At higher speeds, your transmission uses a higher gear ratio to move the vehicle while keeping the RPMs at a low level. Vehicles with a manual or standard transmission are typically called stick shifts.
The driver uses a stick shift to manually change the gears as they accelerate and decelerate their vehicle. Located on the center console, the shift lever is connected to the transmission by a linkage. Besides a stick shift, a manual transmission requires the use of a clutch pedal which is located to the left of the brake pedal. Engaging the clutch pedal disengages the clutch mechanism that is located between the engine and the transmission. Pressing down on the clutch pedal stops power going from the engine to the transmission so you can change gears.
To change gears, the driver presses down on the clutch pedal, moves the shifter to the desired gear and then releases the clutch pedal to reengage the power from the engine to the transmission. Learning to drive a stick takes some practice.
More Control — Perhaps the number one reason drivers prefer the manual transmission is the sense of control they feel over the vehicle. A stick-shift can give drivers an advantage in bad weather conditions or on a hill, as they can shift to the best gear at will.
Many drivers also feel more connected with their car, making driving far more enjoyable. Most stick-shifts are now found in small cars or sports cars. High Focus — Manual transmissions require a greater amount of focus and thought while driving. Drivers are able to focus on the road rather than on which gear they are in. Different traffic situations, like stop-and-go traffic, can be easier to handle because there is no need to keep shifting to match the speed of surrounding cars.
More Power — Automatic transmissions are able to get more power out of their engines than manual transmissions. Automatics set up the gears differently to increase the amount of surface contact between each gear.
Better Acceleration- Modern automatics have better acceleration than manual transmissions. By using the best computers, automatics change gears faster than a human can.
Automatic transmissions can propel the car faster than a manual can. More Innovation — Because automatics are in higher demand, there is more innovation for automatics. Then as I was driving home the rear view mirror fell off. It kept doing it so I rode back and they replaced it. No haggling or anything. With this kind of service I will keep coming back.
I am a repeat customer as they do not dissapoint! Decent prices on the parts you need. Honest and informative workers. Reasonable and efficient service. Overall, no real complaints on my end. Advantages Besides being fun to drive for those who know how! To effect a gear change, selecting first gear, for example, the driver depresses the clutch, disengaging the input shaft.
Using the shift lever, the driver selects first gear, and the linkage moves the shift fork to connect the 1 st -2 nd locking collar with 1 st gear, locking it to the output shaft. Now, when the clutch is released, engaging the input shaft, the output shaft turns because 1 st gear is locked to the output shaft by the locking collar.
As the driver speeds up, selecting 2 nd gear simply involved repeating the process, but moving the shift lever to 2 nd gear. The shift shaft moves the shift fork to disengage 1 st gear and engage 2 nd gear. Releasing the clutch engages the input shaft again, this time routing power through 2 nd gear. Changing to 3 rd gear involves using a second shift linkage, shift fork, and locking collar, this one between 3 rd and 4 th gears.
Because the countershaft and output shaft turn at different speeds, moving from 1 st to 2 nd gear, trying to engage a higher gear while the vehicle is moving slower would be like trying to turn the shaft at two different speeds, which is impossible. Synchronizer rings are like tiny clutches, using friction to bring the locking collar and the gear to the same speed, at which point they easily mesh and power can be reapplied. In comparison to an automatic transmission , a manual transmission is simple in operation and maintenance, and they are known to last hundreds of thousands of miles.
