How Do Gearboxes Fail And What Can You Do To Prevent It

There is nothing more terrifying than healing your gearbox crunching as you pull out of your driveway and out into traffic. Aside from the sheer fear of not knowing what has gone wrong, you will likely feel a certain type of dread bubble up in the back of your mind as you contemplate just how much this is going to cost you. Well, as with anything in life, a little knowledge can go a long way in preventing this scenario from occurring. The following guide will walk you through a few reasons why gearboxes deteriorate and what you can do to keep them in tip-top condition.

Lack Of Lubrication Causes Wear

If there is one thing that cars hate, it’s running dry. In fact, it even even a lack of lubrication that causes damage as old, dirty oil can have the same effect. The issue results because any part of your car that moves will need to be adequately lubricated to avoid overheating and wear. This is especially true in rapidly moving components like the engine and, of course, the gearbox. In any case, if you want to make your car last longer, you really should pay close attention to the dates provided by your vehicle’s manufacturer. Just be aware that this will be a guideline, and you will need to use some common sense depending on your location. For instance, in dustier, rougher areas, your car will likely need to have more regular changes to compensate for the environmental conditions. The best thing to do is to consult a technician who will be better able to advise on the matter.

Incorrect Gear Ratio Wears Parts

If your gearbox has been recently changed and set up incorrectly, you will find that, over time, it will begin to wear down. This can be as bad as improper lubrication but may happen at a slower rate. While rare, it can happen, and if so, you will feel that the car simply doesn’t feel right. Acceleration will feel sluggish, and you might find that the engine is running faster than it should when in a particular gear. The only thing you can do in this situation is to take it into a garage and have them perform a full diagnostic on the vehicle to find out if the issue is indeed a gearbox one.


Towing More Than Your Car Is Rated For

If you regularly haul stuff from one place to another, keep an eye on your truck’s towing limit. This is the maximum amount that the manufacturer has rated it for, and going over can cause all kinds of pain that you really don’t want to deal with. Aside from potentially damaging it cosmetically, overloading it will cause the clutch to wear down and slip and will end up costing you far more in repairs than you anticipated. Moreover, you could find that your warranty refuses to cover the cost if they discover you overloaded it…and understand one thing: they will find out. 

Your gearbox is a critical component of the car and, like the other vital parts, deserves respect. By ensuring that you keep it oiled up and avoid towing more than you can handle, it should last a long time.
