Transmission Repairs: Understanding the Causes of Common Problems

by Emilia Latvala

The failure of your auto transmission will mean high repair or replacement costs. This system is designed to convert the raw energy from the engine into usable controlled power for rotating the wheels. The malfunction of this critical element will cause a complete breakdown. However, you should note that transmission problems are not instantaneous in their occurrence. In most cases, the system deteriorates due to internal damage before it fails. You can prevent a breakdown and other complications by conducting repairs when you notice the initial signs of transmission malfunction. Here are fundamental explanations of the causes of the common forms of transmission wear and damage.

Unusual Sounds 

The transmission system consists of a series of gears that allow for the transfer of power from the engine. If this unit is faulty, the internal system of gears will emit some kind of noise. The specific type of sound produced by a faulty transmission will depend on the type of vehicle, including the model and brand. Usually, manual cars will emit a clunking sound when the gear is shifted.

In automatic transmissions, the sounds will be subtler. For instance, a whining or buzzing sound could be emitted, and you might hear a persistent hum. These problems are often caused by poor driving habits that damage the gears, like the irresponsible use of the neutral mode and shifting to 'park' before stopping the vehicle. Plan for professional diagnosis if you suspect that sounds are coming from the transmission.

Burning Odour

The presence of an unpleasant burning odour could indicate the deterioration of your transmission. In most cases, this type of smell is emitted when the transmission fluid is overheated. Like other fluids in a vehicle, the transmission fluid is used for lubricating the internal components to minimise friction. Moreover, the reduced friction minimises the heat generated by the auto components during operation.

Unfortunately, if the fluid is old, it will be prone to degradation due to the hostile condition. The damaged fluid will not provide adequate lubrication, so the internal components will experience more friction, Moreover, when the materials wear down, sludge will form, contaminating the fluid. You can avoid this problem by changing and flushing the fluid.

Handling Problems

Finally, you should monitor the vehicle for performance issues that could be related to transmission malfunction. For instance, instabilities such as shaking during operation might indicate internal problems, preventing a smooth transition during gear changes. Also, if there are hesitations during gear changes, consult a specialist for transmission repair.
