Can you drive stick? Are you able to double-clutch, instead of driving like your grandmother? Are you constantly refining how you work that clutch pedal? True gearheads of decades past could make a high performance car almost jump straight up in the air with an expertly executed popping of the clutch. Do you know what that means?
Believe it or not, a growing number of drivers don't know how to drive stick. There have been multiple reports in the news lately of would-be car thieves and carjackers who weren't able to take the vehicle simply because it had a manual transmission. Shifting gears yourself is fun, and it provides more control over how a car handles on the road, something people who don't know how to drive stick simply don't understand. If you know how to drive a manual, you're also not limited in the selection of vehicles you could potentially drive, which is another big plus.ÂÂ
Really mastering a manual transmission is easier if you understand how it works. Not only will you shift smoother, you won't engage in bad habits that will wear out the transmission or clutch prematurely. There's a lot going on inside the transmission, so how much do you know about it all? Take the quiz now to find out!ÂÂ
What component connects the transmission to the engine?
coupler
flywheel
clutch
When driving a manual transmission, you have to be keenly aware of the clutch since you control how it operates when changing gears.
When you're moving the stick and hear grinding, what's the sound?
transmission gears
engine cogs
gear selector fork and dog teeth
Despite the common misconception that this is transmission gears grinding, the fact is all the gear teeth in a transmission are always completely meshed.
In modern cars you only need to press the clutch in once when switching gears, but race cars and older vehicles require you to double-clutch when shifting gears.
Keeping the clutch pedal pressed all the way down while stopped does what?
nothing
files down the flywheel
wears out the throw-out bearing faster
Once the throw-out bearing is gone, you'll have to replace the clutch, even if the clutch disc is only partly worn out. In other words, don't leave the clutch pedal engaged when stopped.
What makes reverse gear engage in the transmission?
a special cog
pushing the idle gear into place
The idle gear can slide along the layshaft. Once it connects to the other two gears, the setup causes the output shaft to turn in the opposite direction.
to vary how much power is going to the car's wheels
The torque band on an internal combustion engine is quite limited, but the transmission helps smooth out the differences some, resulting in better performance.
How does the clutch help with smooth gear changes?
It lubricates the gears.
It interrupts the flow of power to the transmission.
When you press in the clutch, it literally disconnects the engine from the transmission, allowing you to switch gears without any of the blood-curdling grinding.
What is the input shaft from the transmission connected to for receiving engine power?
clutch disc
Because the clutch disc spins along with the flywheel, thanks to friction, the input shaft is attached to the clutch as a way of receiving the engine power.
When you're waiting to merge into traffic, what should you be doing with the clutch?
engage it halfway
keep it fully engaged
leave it disengaged
Too many people sit with the clutch engaged, which puts unnecessary stress on the diaphragm spring and pressure plate springs, leading to their failure sooner.
What external force is applied to the clutch disc to begin the transfer of power to it?
gravity
space
time
pressure plate
The pressure plate has a system of springs that are designed to press against the clutch plate, literally transferring power to the transmission itself.
What kind of system transfers the clutch pedal motion to the clutch assembly?
hydraulic
Just like the brakes, pressing on the clutch pedal transfers force through a liquid-filled line, which then actuates a mechanical arm that presses on the center of the diaphragm spring.
What kind of spring in the pressure plate allows the clutch to disengage power to the transmission?
transitive
helical
diaphragm
The diaphragm spring is circular and sits between the pressure plate and a cover. Its design allows for pressing on the assembly to disengaged the clutch.
What device in modern transmissions makes double-clutching unnecessary?
horse collars
synchros
Synchronizers or synchros allow the collar and gear to contact through friction before the dog teeth mesh, allowing them to synchronize speeds in advance.
When you press on the clutch, what happens to the flow of power to a gear?
It doubles.
It cuts out.
If you press on the clutch in your car and keep it engaged, you'll notice the wheels stop receiving power because you've disconnected the torque from the engine to the gear.
What's the basic principle that makes manual transmissions work?
Newton's Fourth Law
gear ratio
Gear ratios greatly affect performance, but it's a principle most car shoppers don't know much about, so they ignore it and concentrate on power solely.
When you park a car with a manual transmission, what should you leave it in?
Any gear will do.
If you don't leave the car in gear, you greatly increase the chances of it rolling away. It is wise to use a forward gear when parked facing uphill and reverse when parked facing downhill.
