Need I press clutch pedal while starting my car in neutral?

It depends on the specific vehicle. Many modern standard transmission cars in the US have a clutch pedal sensor that will not allow you to start the vehicle if the pedal isn't fully depressed. You'...

Need I press clutch pedal while starting my car in neutral?

Being from Canada, I feel compelled to mention that if you do not depress the clutch while starting when it is at all cold out (let's say < 0 Celsius) you will notice the starter motor labouring ...

What's the best gear to leave a manual vehicle in when parked?

The lower the gear, the better the job the engine compression will do at holding the car if the brake fails, that's because a lower gear makes the engine spin faster and requires it to do more work ...

What's the best gear to leave a manual vehicle in when parked?

When I'm on a hill with the front of my car facing up the hill I park the car in first and turn the wheels away from the curb so the transmission is fighting against gravity. When I'm on a hill with ...

Is reverse gear in a manual transmission equivalent to any other gear?

Reverse is pretty equivalent to first gear, for a ratio of around 3.2ish. If it were any lower, it would be difficult to get started from a stop since the torque just won't be there. If you've ever ...

What stops a car window from falling down?

Every window has what's called a window regulator (here's a representative image): The window itself attaches to the window track. This keeps it steady and level while moving up and down. As you can ...

What's the best gear to leave a manual vehicle in when parked?

So, looking at a couple common manual transmission gear ratio charts, first gear would be best. Why? It has the highest ratio. Although it is (in the charts I found) very close to reverse. Here's a ...

Does an increase in horsepower allow a greater speed in any given gear?

The answer is no because you mention being limited by your redline. Regardless of power, a certain RPM will result in a certain speed for a given gearing. Chances are the gear ratios were chosen ...

What differences are there between straight cut and helical cut gears?

Great question! There are several basic differences. Here is my main article that I am pulling from. Firstly, straight-cut gears produce less side-to-side torque, allowing the engine to deliver much ...

Switch from N to D without brake

Should be no problem at all. The manual is being overly cautious, since the usual case for shifting from neutral into drive is when you're stopped hold the brake will prevent the car from starting to ...

Driving down hill in gear without throttle

As you say you change gear from 3rd to 4th, this means you have changed the gear ratio between the engine and the wheels causing a different engine rpm.

Does an increase in horsepower allow a greater speed in any given gear?

Summarized Answer No, HP does not determine MPH in a gear, the gear ratio does. Although there are hypothetical ways that HP can seem to make the vehicle go faster in the same gear, it doesn't ...

Switch from N to D without brake

No harm done On contemporary vehicles there is no direct mechanical linkage between the gear selector and the automatic transmission. Instead, the gear selector selects a "state" (e.g. N, D, R, 1, 2....

What would happen if you shifted into reverse while you are going forward?

My theory is that the engine would be forced to rotate the other way around, wouldn't it? Then, because of that, the engine would stop, and therefore it will "generate" a lot of force to the ...

What's the best gear to leave a manual vehicle in when parked?

First gear when pointing down hill, reverse when pointing up. If your car ends up rolling, the engine will turn in the correct direction. If you park in reverse pointed downhill and your car rolls ...

Does an increase in horsepower allow a greater speed in any given gear?

Well the simple answer is (as you suspect)... No. With fixed gearing, you are going to be doing the exact same speed at any given engine RPM with 100bhp or 600bhp.

"Keep in low gear" driving a gearless electric vehicle

Electric vehicles can "engine" brake by using the drive motors as generators. As they generate electricity they consume the car's potential energy - either from speed or elevation or both. The energy ...

Why do we push start cars in second gear?

It doesn't "have to be done in second gear". It just usually works easier to do it there. The reason is simply as you put it, that being it isn't trying to spin the engine as fast in 2nd gear as it ...

Why doesn't a car parked in first gear roll backwards?

Engaging gear increases the effort needed to move the car Typically (assuming a RWD vehicle): In neutral: car moves when wheels, axles, diff(s), propshaft & gearbox output shaft turn In gear: ...

Difficulty of shifting down to 1st while moving (manual)

There's much older cars that don't have their 1st gear synchronised. My '76 Triumph TR7 doesn't have it, and I bet your Skoda doesn't have it either. You either have to come to a complete standstill ...

Trouble getting in first gear when car is hot

Sounds a lot like the clutch centre plate is breaking up or has oil on it so it is sticking to flywheel face or pressure plate. Check and replace as needed.

Manual transmission noise

One possibility is that the synchromesh has worn on 3rd gear. The synchro is a clutch that matches the speed of the gears before they mesh together. If the synchro is worn, then the gears will not ...

Need I press clutch pedal while starting my car in neutral?

In my opinion, this is a good practice to adopt. Pressing the clutch means that you disconnect the engine from the gearbox. Consequently, the power needed from the starter motor will be less. This ...

Riding motor cycle in a slow moving traffic

I suppose it depends on a wet or dry clutch. A wet clutch doesn't have a thrust bearing and so you cannot "ride it". A dry clutch has a thrust bearing so the diaphragm on the clutch is pressing on it ...
