2. Gearbox problems

The running rotor keeps a manual transmission busy with the gear in every manual transmission vehicle. Sometimes you might notice it hurting your knuckles by jumping out quickly. And in some other cases, especially when driving upward or decelerating, you will notice the transmission could be decreasing at a rapid rate. This is one of such common problems with manual gearbox that needs immediate attention for safety.

4. When engaged into gear, transmission scratches

This commonly occurs when you have a new clutch installed and it is like one of the most common manual transmission problems. So, what is happening underneath during this problem?

First possibility is: the vehicle’s synchronizer rings are not slowing down somehow and failing to engage the gears. You will notice that as you try to engage the shifter, you are feeling a scratch. The gear won’t engage as a result of worn out synchronizing rings that are failing to slow down when they are supposed to act like a kind of brake on the gears.

You would also face this kind of manual transmission problem if you use the wrong fluid type. To avoid this problem, ensure that you always use quality and appropriate oil in your manual transmission and to also prolong its lifespan while maintaining its good health.

5. Clicking, knocking and ticking noises

Different sounds in a manual transmission indicate different problems with such system. Let’s briefly talk about some of the common noises and their indications:

  • Bearing or ticking noise: This is indicating a wrong gear.
  • Knocking sounds: This is indicating a broken or damaged gear.
  • Clicking noise: This is indicating probability of a broken tooth.

We advise you consult your local automobile expert or mechanic as soon as you notice any of these noises to avoid further damages in the internal mechanism of your manual transmission.

6. Gear won’t engage in cold weather

It is common in manual transmission for the gear not to engage when the surrounding temperature is nearing zero. It might be this way until the mercury hits back the regular line again. This is a common problem that mostly result from issues with your hydraulic clutch or your engine being low on lubricant. You can get a lighter oil and try it in to fix this problem and if it’s getting out of hands, take the car to an automobile mechanic or the local repair shop.
