How do I know if a repair is necessary?

The gearbox is designed for a long service life equivalent to that of your car, at least under normal conditions of use. It should therefore last at least 300,000 km.

Signs of wear on a manual gearbox

In practice, various factors can reduce this remarkable longevity, such as :

• Aggressive or abrupt behaviour ;
• Neglect of gearbox checks and maintenance (checking fluid levels, topping up oil, changing oil, etc.);
• Shocks repeatedly ;
• Use of excessive force when operating the gearshift lever;
• A malfunction in the mechatronic system;
• Road conditions.

Gearbox problems rarely go unnoticed. and should be taken into consideration to optimize the life of your gearbox.. In fact, there are many signs help you identify the presence of a fault. Ey paying attentionyou'll easily spot them.

Indicators of wear and tear can be heard in the form of noises, such as continuous whirring.. This usually means that the bearings mounted on the drive shafts are in poor condition: there's a risk of them breaking and destroying the entire BV.

If it becomes impossible to engage the gearshift lever in one or more positions, the gear selection system is probably blocked or the linkage has failed. Lack of oil or dirt may also be the cause. may also be to blame.

You hear creaking when shifting gears or gear engagement becomes complicated? This may be a sign that the synchros are worn or that the gears are not sufficiently lubricated, preventing them from meshing with the pinions.

Symptoms may also vary according to depending different types of gearbox. In most cases, failure of a manual BV are manifested by difficulty in changing gear ratios, or the feeling that the gearbox is hard, leaving you with the impression that it's resisting you. It may also be the case that gears skip or the transmission system becomes abnormally noisy. Finally, in some cases you may notice oil leaks under the gearbox housing.

Signs of wear on an automatic gearbox

For automatic gearboxes automaticyou need to be vigilant if you notice jerking during starting and acceleration. Similarly, it's a good idea to have your BVA checked quickly if you hear any grunting or squeaking noises that seem to be coming from your gearbox. Difficulty downshifting and loss of power are also warning signs to be heeded.

That's for sure, these signs of malfunction are not exhaustive. If they do occur, or if you notice any other form of malfunction, make an appointment immediately with a qualified mechanic. Driving a car with a BV that is not at its best is a risk for the vehicle's occupants and the driver. a risk to vehicle occupants and other road users. Add to this the fact that minor faults may be amplified and spread to other gearbox components, resulting in more serious failures that are more difficult to repair, and therefore more likely to cause serious damage.more difficult to repair, and consequently more costly..

How do you identify the right type of gearbox?

The gearbox can be considered the core of the core of the transmission system, since it links the the wheels and the engine of a vehicle. There are several several types of gearbox mechanical and automatic.

The manual manual is the most common on the European continent: it features a series of gears that enable the driver to select a gear by operating the gearshift lever while depressing the clutch pedal. In other words, the driver's intervention is for every gear change. ! The 5-speed manual gearboxes and 6-speed gearboxes are in the majority on the automotive market. However, it is possible that your vehicle may have up to 7 speeds manual gearboxes.

Gearbox operation

BVMs all work on the same principle same principle : l'input tree called also known as the main or primary shaft, is connected to the motor via the clutch system, and transmits its rotation to the intermediate shaft, which in turn drives the secondary shaft. The secondary shaft carries the pinions linked to the transmission ratios.

When you operate the gearshift, the linkage transmits the command to the gearbox. the gearbox. A fork will then move, triggering the movement The gearshift lever slides until the pinion corresponding to the selected gear ratio locks onto the secondary shaft.

Extremely popular in the American and Asian marketsautomatic gearboxes are becoming increasingly popular in Europe. Manufacturers generally offer them as optional extras, but some models are supplied with with an automatic gearbox. They differ from manual gearboxes by the fact that the driver does not need to intervene, and by the absence of a clutch pedal.. The number of gears is also higher on this type of gearbox. Although the norm is around 6 automatic gears, BVAs can have as many as up to 9 or 6 gears.

The different positions on the automatic gearbox

Another element can also be associated with the overall mechanism of automatic gearboxes: the gearshift. However, its function is not to engage a gear, its function is not to engage a gear. Each position in the gearshift gate determines a driving mode on which the system selects transmission gears. The standard positions of the automatic gearbox are as follows:

• P = Parking : lhe wheels of your car are blocked when you activate this mode;
• R = Reverse : cThis is the position to select before reversing;
• N = Neutral : lhe vehicle is in neutral. Its wheels may turn;
• D = Drive : lhe gearbox is in forward mode. The system analyzes driving conditions and selects gears without your intervention;
• S = Sport is an additional mode found on many cars designed for sporty driving;
• W = Winter : is a useful mode when the wheels are slipping. Start-ups on ice and other slippery surfaces are carried out in second gear ;
• 1 = your vehicle is in first gear only;
• 2 = automatic gearbox alternates between first and second gear ;
• 3 = available on certain vehicles, it allows the transmission system to alternate between the first three gears.

Sequential gearboxes are not a type of gearbox in the strict sense of the term. additional function inherited from Formula 1 transmissions! Like the automatic gearbox, it has no clutch pedal. Instead, the driver selects controls via a steering-wheel-mounted steering-wheel-mounted paddle-shift or by operating a gearshift lever.

The robotized gearbox is a hybrid version.version, as it is basically a mechanical gearbox.. However, its design also includes an automated management system. So you can switch between manual and automatic gear selection with ease!

Visit gearboxes are interchangeable, as each type of gearbox is manufactured according to a specific architectureEach type of gearbox is manufactured to a specific architecture, according to a particular vehicle model and to standards adapted to the car's operating conditions. What's more, automakers tend to evolve their transmissions as new generations of a given model are launched. So it's essential to know which type of gearbox your vehicle is equipped with and which part number corresponds to it.

The model number is a reference code stamped on the housing. In some cases, the manufacturer may write it on a label. This series of numbers or letters will enable you toformally identify which components are compatible with your gearbox for repair purposes. It's also the same reference that should be taken into account if replacement is essential.

In the event of critical failures, he will choose to replace the gearbox with a used model or a standard exchange.

Assembly

Assembling a BVM is tediousyou have to reposition the gear train and axle, fix the bearings, position the transmission, etc. The seals and screws to be used vary from model to model, and there's no point in making a mistake, otherwise the gearbox's efficiency will be compromised. Once the gearbox has been correctly reassembled, the housing is filled with fresh oil. The garage then proceeds to a test phase by shifting the gears one by one, to ensure that the malfunctions have completely disappeared and that the gearbox is ready for safe use. safe to use.

In the case of an automatic gearbox, it's not enough to follow the removal and installation steps to the letter. In addition to the necessary checks and tests, reprogramming the reprogramming of the system is usually required.
