Ideally, your car gearbox should last the life of your car, but many times they tend to fail before their time because of certain avoidable actions. The life of a gearbox can be one of the biggest concerns for new car buyers because they are expensive to replace and it can be difficult to predict their lifespan.
Transmission lifespans are determined on a case-by-case basis, and are determined by a number of contributing factors. Some transmissions can last just over 16,000 kilometres, while others will last over 300,000 kilometres. Generally though, regular vehicle maintenance is the number one factor that can determine the lifespan of a gearbox, and good upkeep can help it last even longer.
The transmission is linked to other parts of the car like the chassis, engine, electronic systems, and differentials. Problems in the gearbox will lead to problems with these other parts of the car and vice versa. This is why it is very important to keep your transmission healthy and help prolong it’s life as much as possible.
While it’s almost impossible for anyone to come up with a definite answer on how long a specific car’s gearbox will last, regular maintenance and attention to a number of factors can help you prolong the life of your transmission.
Driving habits have a large impact on the longevity of your transmission. Accelerating quickly and hard braking increase the chances of your transmission wearing out before its time.
As such, it is best to avoid these habits for the sake of your vehicle and transmission. Like most parts of a vehicle, excessive kilometres can also cause transmissions to fail before their time. Just like most of these factors, this can however be dependent on your type of vehicle as well.
Some car manufacturers have reputations for having durable transmissions that are able to handle more wear and tear than others.
Lubrication/Fluids & Heat
Transmissions are designed for specific purposes. They are able to tolerate and work with specific types of fluids. Not all fluids are equal and right for every type of gearbox.
As a matter of fact, there are over fifty different types and grades of gear fluid available for car gearboxes. Each type and grade provides a different amount of slip for your vehicle.
Slip affects the amount of heat generated to your transmission; meaning the gear fluid has a big influence on heat and pressure placed on your transmission.
The more heat placed on a transmission the shorter their lifespans become. This is because Heat causes the gear fluid to fail and this makes components to break down, and for the car’s lifespan to drop fast.
Keep your transmission fluid at the right level and change it regularly, so that the intricate parts of your gearbox don’t grind together and damage the transmission.
