Computer Cross Talk: Failing automatic transmission

Advertisement

An automatic transmission, also called automatic gearbox, is a type of motor vehicle transmission which automatically change gears as it transmit power from the engine to the driving wheels with the purpose of moving the vehicle thereby freeing the driver from having to shift gears manually while driving. Many new automatic transmissions are electronically controlled and as such are considered to be the most complex and complicated transmission system in the modern vehicles.

The main components of modern automatic transmission are mechanical systems, hydraulic systems, electrical systems and computer controls. The working of all these components is so quick, instantaneous and in a perfect harmony that you never notice them until or unless there is a problem.

Transmissions take a lot of use over the years as the interconnected parts move, rub, heat up and interact with other internal and external components. Because of this continual exposure to friction and heat, it is natural that your transmission components will experience wear and tear. With passage of time, one or another part may fail to work as effectively as it used to do often.

In order to repair the problem you may sometimes need to replace the things which are not working properly and, at the mention of the words ‘automatic gearbox repair’ many car owners cringe and their wallets run for cover because automatic transmission repair can quite be both an expensive and confusing experience for car owners.

However, with certain things in mind you can easily fix the problem and save your money. Of paramount importance is early diagnosis of a problem and, if not fixed, will inevitably become worse. Even the smallest issue can lead to major repair bills and the longer you drive with a malfunctioning transmission, the higher the repair costs will be. The best thing you can do is have an automotive professional look at your automatic transmission and make recommendations for repairs. The transmission is a complex system and should only be worked on by a trained specialist.

As mentioned earlier on, transmission repairs can be expensive, so it is worthwhile to pay attention to anything that seems unusual. Because the automatic transmission is the most complex piece of machinery in your entire vehicle, by no means can a list of warning signs be all-inclusive. With that said, we will in the two weeks discuss the most common problems that have been observed by transmission repair specialists over the years.

These are the early warning signs that you want to look out for. So if you think you may be having some car trouble or if you are just looking to learn more about potential transmission problems, check out signs of transmission trouble and stay one step ahead of your car.

For a start, one of the most common transmission problems has to do with the automatic transmission fluid. This fluid, which is usually bright red for most cars, is absolutely vital in ensuring that your vehicle’s shifting capabilities are functioning properly and will continue to do so by keeping the transmission cool and also lubricating the internal parts. So if you see a red puddle when you move your car from the garage or parking lot, it is almost certainly the automatic transmission fluid which is leaking. If you have to top up your transmission fluid very frequently, that is also a sign of a leak.

Leaks in automatic transmission cars tend to develop in a few places and should never be ignored for sure. One place that a leak can develop is the speed sensor pointing mount, which is found on the transmission’s housing. The drain hole beneath the transmission box and the filler tube base are also common leak locations.
