How To Fix Your Gearbox

by William Gist

When your car starts adding a lot of years under its “belt”, it might start running into a few problems as well. Just like us humans, cars tend to age as well, and if not properly maintained, they might finally give up and break.

One of the most common car problems that we can run into nowadays is the “gearbox problem”. The gearbox is where all the gear-switching happens inside the car, and if something goes wrong in that particular area, you might start experiencing trouble while trying to switch from one gear into another.


Here’s how to detect such issues, and a few potential ways that you can fix the gearbox. Without further ado, let’s take a look.

How to detect Gearbox Problems

When it comes to Gearbox issues, there are a few ways that you can “spot” a problem. Most drivers get “attached” to their cars, so whenever something doesn’t “feel” right, they can feel it. One of the most common cases for this is when the shifting gears feels odd. An experienced driver will instantly hear and feel that something’s wrong with the Gearbox. Also, if you hear any grinding sounds that don’t sound pleasant at all, there’s definitely something that needs to be done.

Some methods are much cheaper than others, but sometimes they happen to work and save the day, so why not try them. Let’s start with the most basic and cost-efficient method.

Checking for transmission fluid


Inside your engine bay, there is a certain amount of transmission fluid that your car needs to have in order to perform the gear-switching without any issues. If that fluid is running low, you might start experiencing issues with your Gearbox. One of the best and most cost-efficient ways to fix this problem is to check for the amount of transmission fluid in the reservoir, and add some more if it’s running low.

Replacing faulty gear synchros

Your Gearbox contains more than a few gears which all need to be functioning properly. If one of them is faulty and left unattended, it can cause severe damage to the rest of the gearbox. If you notice that one of the gears is significantly damaged and faulty, you should consider replacing it as soon as you possibly can. If you don’t know how it’s best to ask for professional help.

For automatic cars, for example, the car shifts its gears by itself, so if the sensors are not properly determining at which speed the vehicle is going, or how much it is accelerating, it might start shifting poorly, which will lead to an unenjoyable experience, and in a worst-case scenario, an accident. Automatic cars need to be taken on a service from time to time, in order to make sure that everything is performing the way it should.

Also, in manual transmission cars, you need to make sure that the right kind of transmission fluid is used, because if it is not, you will still run into problems shifting gears. In cases of wrong transmission fluid, you need to visit a service in order to fully wash it out and apply a new one.
