Driving a manual transmission car, car enthusiasts will know it well, offers the most fun and rewarding driving experience. But it also requires some skill and attention, as if you’re not careful, it’s the driver’s ‘ordinary’ problem.their car jerks or stutters when shifting gearsYou can experience the situation.

cause an uncomfortable driving experience, reduce fuel consumption and damage your engine/transmission over time this is really frustrating. There are several reasons for this frustrating situation, the obvious one being the wrong equipment, of course. Let’s talk about it, then we will come to other reasons and measures.

Let’s answer our main question first: why do we shake when we put the car in the wrong gear?

The shocks caused by shifting the car into the wrong gear can damage the engine and other mechanical parts. caused by overload. The car has multiple gears designed for different speeds and torques, and the right gear selection ensures efficient movement of the car. However, shifting into the wrong gear can cause overload due to an incorrect ratio between speed and torque in the engine.

For example, if a gear is selected that does not match the speed of the vehicle as the car slows down and the driver presses the clutch pedal to shift to the next gear, the torque in the motor increases unnecessarily. This excess torque causes gears and other mechanical components in the engine and transmission. overload causes. This can cause the vehicle to vibrate or even damage it.

Therefore, it is important to shift into the correct gear while driving. Each car comes with an owner’s manual that determines which gear is best suited for which RPM and torque range. If you accidentally shift into the wrong gear and don’t shift right away You may experience serious malfunctions.

What are other common causes of car shaking when shifting gears?

There are many reasons why your vehicle may jerk when shifting, other than shifting into the wrong gear, but they can all be summed up in one point: mismatch between engine speed and transmission speed.

When you shift gears, the engine speed is matched to the speed of the transmission. You must synchronize. Shifting gears too early or too late, or releasing the clutch too quickly or too slowly will cause a sudden change in torque, causing your car to jerk.

Apart from this main reason, there are several reasons why your vehicle vibrates when shifting gears. Let’s see them together:

Worn or defective spark plugs

Spark plugs are small devices that create sparks to ignite the fuel-air mixture in engine cylinders. If worn or defective They can cause misfires, causing your engine to run unevenly and jerk when shifting gears. You should replace your spark plugs every 30,000 miles on average or according to your manufacturer’s recommendations.

Clogged or dirty fuel injectors

Fuel injectors are devices that inject fuel into your engine cylinders in a precise amount and timing. If it is clogged or dirty to disrupt the engine’s combustion process and cause jerking or misfiring when shifting gears. they can provide too much or too little fuel. You should have your fuel injectors cleaned or replaced every 50,000 miles or according to your manufacturer’s recommendations.

Low transmission fluid level or dirty transmission fluid

Transmission fluid is a lubricant that keeps your transmission components running smoothly and efficiently. If your transmission oil level is low or dirty can cause your gears to slip or squeal, causing your vehicle to jerk or shake.

You should regularly check your transmission oil level and 48,000 You should have it replaced every mile or according to your manufacturer’s recommendations.

Faulty clutch components

The clutch system includes the clutch pedal, clutch disc, pressure plate and flywheel. Each of these components if it is worn or damaged It can cause your clutch to slip, seize or squeal, causing your car to jerk or vibrate when shifting gears.

You should have your clutch components checked and, if necessary, every average 80,000-160,000 mileage or according to your manufacturer’s recommendations.

Faulty engine or transmission mounts

Engine and transmission mounts are rubber or metal brackets that hold your engine and transmission in place and absorb their vibrations. One of these wedges if it breaks or wears out can cause your engine or transmission to oversteer, causing your vehicle to jerk or wobble when shifting gears.

You should have your engine and transmission mounts checked and any average if needed 160,000 mileage or according to your manufacturer’s recommendations.

What should you do to shift without shaking the car?

The best way to avoid jerky shifting is smooth, precise shifting. Here are some tips to help you with this:

Watch your revs and speed.

to help you determine when to shift gears. your tachometer (indicator showing your revolution) And speedometer needle (Indicator showing KM/H) you can use.

A general rule of thumb upshift when it gets to about 2500-3000 and cycling It downshifts when it dips below 1500-2000. However, this may vary depending on your vehicle model, driving conditions and personal preference.

Use the clutch pedal correctly.

When you depress the clutch pedal, you should do it smoothly and completely until you reach the ground. When you release the clutch pedal, gradually and gently until it returns to its normal position. you should. Do not release the clutch pedal too quickly or too slowly; this will cause jerking or misfire.

Adjust the engine speed and transmission speed.

When shifting, you must match the engine speed to the transmission speed of the new gear. This gas pedal You can use it

If you move up, Before depressing the clutch pedal, reduce the engine speed by slightly releasing the accelerator pedal. must. When you switch back, Before depressing the clutch pedal, increase the engine speed by lightly depressing the accelerator pedal.. This will help you achieve a smooth transition between gears.

Sometimes when you shift gears, even if you follow these tips your car may still vibrate, which indicates a problem with your transmission or other parts of your vehicle. There it would be useful to look again at the problems in our first subtitle.

As a result, jerking or misfiring while shifting can be frustrating and dangerous, but with proper driving techniques and maintenance and can be corrected. By following our tips you can prevent these problems and extend the life of your transmission and engine.
