Another name for the transmission is the gearbox. While maintaining a constant engine speed, the gearbox employs a system of various gear ratios to ensure smooth operation at all engine speeds. The gearbox also enables the engine to develop torque and achieve high speeds at the wheels.

Your car’s gearbox is more complicated than just that tricky gearstick. The transmission of the car includes a gearbox, which adjusts gears to change speeds and increases torque. As a durable mechanical component, the gearbox should endure for a very long time if it receives regular maintenance.

Even with regular maintenance, your gearbox may experience problems because nothing lasts forever. So, in order to maintain a gearbox in top shape, what issues should you watch out for and what driving forces come into play?

What is the Gearbox’s Life Expectancy?

A well maintained gearbox should serve you for many years whether you drive an automatic or manual transmission. The duration will vary depending on your driving style, whether you’re towing hefty items, and even the outside temperature. In spite of this, a gearbox or transmission may only last the lifetime of your car with typical driving or it may last as little as 5-7 years. (Occasionally, a small amount of chance is involved.)

Because they are very straightforward and provide the driver more control over shifting gears, manual gearboxes typically last even longer.

What Damages a Gearbox?

Since the gearbox in your car has several moving parts, it depends on transmission fluid or gear oil to keep it cool and lubricated. It’s crucial to use the right fluid for your automobile and to replace the fluid on a regular basis because the quality and age of the fluid can have a significant influence.

Driving fundamentally, such as coming to a complete stop before switching from Drive to Reverse and vice versa, will result in less physical stress being exerted on the gears and increase the lifespan of your gearbox and transmission.

If you drive a manual, doing basic things like making sure you always fully depress the clutch and avoiding resting your palm on the gearstick will help keep the gears in good condition.

How Can You Tell If Your Gearbox Needs Repair?

Early detection of gearbox issues could make the difference between a straightforward fix and a complete overhaul of your transmission. Here are some issues to watch out for:

Fluid leaks: If you notice red (or amber for manual transmissions) or amber fluid under your automobile, your gearbox is dripping. Your gearbox needs all of its fluid to maintain proper lubrication and prevent overheating, so you must have the leak rectified right away.

A burning odour: If you detect a burning odour, your gearbox may be overheating, which is not good. It indicates that you either have a leak with insufficient fluid to keep it cool or that you have used the incorrect transmission fluid for your car. As said above, head to a professional as soon as possible.

Slipping gears: When your car shifts into a gear that isn’t appropriate for its speed, this is known as slipping gears. Other warning signals include a lack of response or a delay in acceleration after changing gears. Driving it in this way is risky and may result in overheating.

Clutch malfunctions: If you’re driving a manual car and nothing happens when you depress the clutch, your gearbox may be malfunctioning and urgent repair is required. This might also indicate that your clutch is damaged or no longer functional. This would require inspection as soon as possible.

How Is a Gearbox Maintained?

Although it is understandable if you neglect gearbox maintenance, doing so is the single most effective way to prevent expensive problems down the road.

The simplest method is to frequently check the fluid in your gearbox or transmission. To do this with an automatic, you must first warm up your vehicle and make sure it is parked on a level surface. Check the owner’s manual to be sure; depending on your automobile, you might need to switch it off in order to check the fluid. Check the dipstick in the engine area under the hood once it has warmed up. If the fluid level is below the top point, it needs to be topped off. Move slowly because it’s difficult to remove and too much oil is just as terrible as not enough.

The best course of action in this situation is to take your car to a repair and have them check it for you because life is never straightforward and some automatic automobiles don’t have a dipstick while no manual autos have.

Also pay attention to the colour; if it is dark brown, black, or bright pink, it has to be replaced.

How Can I Prolong the Life of My Gearbox?

Knowing how to maximise the lifespan of your gearbox is important because there are so many factors that can affect this.

Your gearbox will be safeguarded from excessive wear and tear if the fluid is changed every 40–80,000 km for a manual and every 60–160,000 km for an automatic depending on use, condition, and prior maintenance.

A more regular change is a good suggestion if you’re hauling large things or stop and start a lot when commuting. Your gearbox will experience increased strain as a result of these circumstances since it will become hotter and the oil quality will degrade.
