Automatic transmissions of Mercedes-Benz
Since the history of this car brand is very long and there are many different types of transmissions, we will give you a brief overview of the most common transmission with 5 and more gears. In addition, we also provide the recommended oil change interval and the type of oil that should be used.
3 myths about oil change in automatic transmission
Myths are something that professionals in every field must fight with. There is always someone who knows better, and also those who believe those who say that they know better. We are now rejecting three of the most common myths one by one.
Why is it necessary to maintain an automatic transmission?
In short, a transmission needs to be maintained because the oil inside will be used up. It may sound strange, but when you read on, you’ll find out what happens to the transmission oil. After that, there’s nothing strange about this for you and maybe you are even going to think about your car’s transmission maintenance.
What is an oil friction factor of an automatic transmission?
The lifetime of the clutches and the maximum capability to transfer the force from the engine to the wheels depend mainly on the friction characteristic of the discs. Thus, the clutch engagement is critical and one of the most important features of the transmission.
What to do if an automatic transmission is broken
Pay attention to the age and value of the car (price now with a broken transmission and price with a transmission that is in order). It is important to consider the different options and to DEFINITELY estimate the TOTAL financial cost and also the time spent!
Transmission fluid level and how to check it
Adequate transmission fluid level is like A and O – it is absolutely necessary for the transmission to work! The transmission oil pump must be able to suck oil freely when cold as well as when hot, while driving in a curve and being inclined. Transmission oil is like a circulatory system, without which the transmission does not work.
7 questions to the gearbox service company
There are certainly many trustworthy gearbox service companies in Estonia, but there are also some who might be worthy of staying away. Here are some suggestions on how to distinguish grains from the husks.
Automatic transmission and automatic transmission types
All transmission have one common line – different transmission speed depending on the need and the possibility to change the direction of wheel (reverse gear). There are in fact different types of transmissions and it is more common to distinguish between them according to whether the traction is interrupted or not at the moment of changing the gear.
CVT – Continuously Variable Transmission
Leonardo da Vinci actually designed the continuously variable transmission (CVT) in 1490. The first patent, on the other hand, was taken by Daimler and Benz 1886, but it became popular only in the 1950s when the Dutch company van Doorne introduced the transmission to its DAF buses without gears.
Dual-clutch transmission (DCT or DSG)
The history of dual-clutch transmissions (DCT) dates back to the First World War, but the first running transmissions were made for racing cars in the 1980s. Over the past decade, this type of transmission has made a very strong comeback and has increased its share in the market.
Planetary automatic transmission
Planetary automatic transmission is the most sophisticated transmission type that uses different gear mechanisms (planetaries) to achieve different transmissions or gears.
What is ATF? Why the oil is needed in the automatic transmission?
Transmission oil is not a regular oil, but rather a cocktail with very different ingredients. Therefore, the acronym ATF ( automatic transmission fluid ).
Why the automatic transmission must be checked before the oil change?
Transmission maintenance is definitely not a miracle cure for the transmission. However, each alarm in transmission may not yet be related to malfunction, but may also be caused by outdated oil. Correct maintenance can alleviate the abnormalities caused by the oil itself or the wear of the transmission.
Automatic Transmission Software – what is at stake
Automatic transmission software is controlled by a computer that, in accordance with the information coming from the engine, decides which gear, when and how to turn. Seems easy? Unfortunately, the transmission situation is constantly changing, which makes it quite complicated.
The machinery and equipment of Hõbenool
Hõbenool uses special automatic transmission maintenance and repair equipment in its work. We give you a brief overview, starting with a more complex one and moving towards a simpler one.
10 tips for the buyer of a used transmission
If you have decided to buy a used transmission and made a price calculation, then you have 10 questions to consider.
Used gearbox instead of repair?
The used gearbox is, in some cases, more sensible than repair, but you should make clear what you need to consider when purchasing it.
Automatic transmission repair price and its formation
Automatic transmission repair cost is comprised of three large groups: dismounting and installing the transmission, opening and assembling the transmission, and spare and cost components of the transmission.
Unfamiliar fluid (water or coolant) in the transmission!
How does an unfamiliar fluid gets into the transmission, how to control it and what to do in such a case?
Because of what the main automatic transmission errors arise?
Most of automatic transmission errors are due to outdated oil, i.e. situation where some of the properties of the oil are above the critical limit.
How long is the lifespan of an automatic transmission?
Car manufacturers design (taking into account the average user) transmission as weak as possible and as durable as necessary to ensure minimum costs during the warranty period. They are trying to operate opposing parameters.
Is it necessary to change the transmission oil and how often it must be done?
If you want the transmission to last at least as long as, for example, a vehicle engine, the answer is YES. How often is it necessary to maintain the transmission? For example, the world’s largest transmission manufacturer Aisin Seiki (owned by the Fortune Global 500 list) suggests changing oil even every 2 years and after 20,000 km.
What services do not tell you about the automatic gearbox oil change?
The transmissions have become so complicated that car manufacturers have no real ability to train highly qualified personnel and buy special equipment in their dealerships around the world.
Original oils vs newer oils of the automatic transmission
It can be said without exaggeration that there are hundreds of different certificates/codes from oil manufacturers. Even car repair workshops and spare parts sellers cannot navigate there, not to mention the ordinary user.
What constitutes the price of oil change service?
The price of the service is determined by several components – the time of work (complexity), the cost of spare parts, i.e. the amount of oil, the brand/type of oil, the price of the gasket and the filter.
Approach based on the gearbox not car brand
Most of us are able to identify the car brand on the street or at least know what car we own. With automatic transmission, the situation is much more complicated. Often, even repair companies do not know which manufacturer’s automatic transmission is under the car. Why is it like that?
Which specific benefits do I get when I change oil vs. don’t change
Transmission oil is not eternal. The marketing term lifetime means that the transmission oil is for a lifetime, not eternal. Unfortunately, its lifetime is not defined anywhere
