Do I Need Gearbox Repairs

The transmission within a vehicle is a vital part of its functioning. It controls the administration of power from the engine to the driveshaft and therefore overtime is subject to a substantial amount of wear and tear. The wear and tear are produced by a selection of parts moving to cause heat and friction to be generated and overtime can incur damage that requires gearbox repairs.

What Do I Look For To See If I Need A Gearbox Repair?

Here we explain the tell-tale signs that your gearbox repairs are needed and how you catch these problems early.

Humming Noises

Noise from your vehicle could be one of the first signs of a transmission problem and highlights that gearbox repairs may be required. However, when you can hear an irregular noise coming from your vehicle, it is hard to tell the exact problem without help from an expert. The sounds produced by your gearbox can be described as a humming, buzzing or whining noises. It is important to note the sound your car will make will depend on the make and model, but it is fair to say you will be able to notice a difference in the sound of your vehicle if there is a problem with the transmission.


Leaking Fluid

One key sign that your transmission needs repairing is leaking fluid. Fluid leaking from your transmission is a common cause of a breakdown and therefore gearbox repairs are needed as soon as possible. The ATF or automatic transition fluid within your gearbox is an essential part of the running of this component. The ATF has the role of cleaning, conditioning and lubricating the seals within your gearbox as well as acting like hydraulic fluid.


Slow Response Time

When shifting your vehicle from park to drive, the gearbox should instantly go into the correct gear. In automatic vehicles, gearbox repairs are needed when there is a delay in the gear engagement, which should be noticed by the driver when shifting into drive.

In manual transmission vehicles, the same lacking response is experienced but can be noticed by the increase in revolutions per minute (RPM). This will make the car sound like it is going a lot faster than it is and in turn, it is important to get this looked into by a professional.


Shaking or Grinding

When driving your vehicle you shouldn’t experience any shaking or grinding feelings due to your car. However, these symptoms can be a sign there is an issue with your gears and is a common reason for gearbox repairs.

Gears grinding is a noticeable problem with manual gearboxes. This will be felt when shifting gear and if the noise occurs after the clutch is engaged, it may be a sign repair is needed.


What is a glossmeter?

A glossmeter is also referred to as a gloss meter. It is an instrument which is used to measure the reflection of gloss on a surface. The gloss is determined by projecting a beam of light at a fixed intensity and angle onto a surface and measuring the amount of light which is reflected at an equal but opposite angle.

There are many gloss meters available in the market depending on the type of service you wish to measure gloss on.

Construction of a gloss meter                                       

A typical gloss meter consists of a mechanically assembled light source that projects a parallel beam of light onto the test surface to be measured and filtered to receive and locate the rays of light reflected from the surface.

Development of a gloss meter

A gloss meter is the most useful instrument in marketing for the purpose of measuring gloss. However, unfortunately, it is not sensitive to other common effects which reduce appearance quality including haze and orange peel. There are other instruments in the market which can do this though.

Haze = the surface will have a milky effect and is caused by a microscopic surface structure.

Orange peel = this is caused by an uneven surface distorting the light reflection.
