As one of the world's leading luxury car manufacturers, Mercedes-Benz is at the receiving end of consumers' high expectations, and their transmissions don't fail to deliver. The transmission plays an indispensable role in transferring power from the engine, and car manufacturers are constantly striving for better power transfer efficiency and durability of transmissions. Daimler AG produces Benz transmissions, renowned in the automotive world for their reliability, hassle-free maintenance, and smooth and precise gear shifting. Are you in the market for a Benz transmission? Keep reading on to learn all about this Benz part and to avoid common mistakes when buying one.
Key Features of Mercedes Benz Transmissions
Smooth & Precise Gear Shifts
No transmission shifts gears as smoothly and precisely as those used by Benzs. Benz transmissions have been engineered to deliver smooth gear-changing for the most enjoyable drive possible.
Fuel Efficient 7-Speed Automatic Transmission
A standout of the Benz transmission lineup is their fuel-efficient 7G-tronic 7-speed automatic transmission. As found in many 2013 models, this version has an advanced torque converter lock-up clutch that adds durability, increases fuel efficiency, and delivers more responsive driving and quieter operation.
Direct Select Shift Lever
Direct Select is a feature in modern Benzs that enables drivers to more easily switch gears between drive, reverse, neutral, and park. In Benzs with Direct Select, the lever that usually controls the windshield wipers can be toggled through the different gears, sending an electronic signal to switch gears.
Sourcing Mercedes Benz Transmissions (OEM vs. Aftermarket)
When you purchase a brand new Benz, it comes with an Original Equipment Manufacturer (OEM) transmission made by Daimler AG. Transmissions made by third-party manufacturers and usable in Benzs fall under the "Aftermarket" parts category.
Unless the transmission of your Benz is out of production and impossible to find, we recommend investing in an original Benz transmission to return your car to its original level of performance. Because of the more stringent levels of manufacturing, you'll likely get more use out of an OEM replacement. Aftermarket transmission might not only be excluded from Benz's warranty, but they could also void the warranty and even damage your vehicle when installed. Moreover, they might not even fit into your Benz properly. When it comes to an expensive part like the transmission, it's prudent to avoid taking chances and to go with the original.
Tips for Verifying the Quality & Condition of Used Transmissions
There are several ways to tell if a used transmission is likely to last:
1. Check that it is free from any leaks, as these could point to faulty seals and o-rings.
2. Be on the lookout for rust, as it could be a sign that some of the transmission's metal parts are corroding.
3. Make sure it comes with all the required documentation showing if it has gone through any major repairs (avoid those that have received any).
If missing, stay clear of it no matter how good it looks.
Types of Mercedes Benz Transmissions
Automatic Transmission
To change gears, automatic transmissions use a mechanical clutch that is controlled automatically through electronics, pneumatics, or hydraulics instead of manually through a clutch pedal.
Benz automatic transmissions include their highly fuel-efficient 7G-tronic.
Tiptronic Transmission
Benz transmissions equipped with Tiptronic technology enable the driver to switch between automatic and manual driving modes. Their transmissions with this capability include the 7G-tronic and the 9G-tronic automatics.
Manual Transmission
In manual transmissions, gear shifting is performed manually with a gear stick and clutch. With proper operation, manual transmissions allow vehicles to achieve better performance and fuel efficiency. Manuals come with a learning curve, however. One such manual transmission is Benz's C180 six-speed, which is stylish and fuel-efficient.
AMG Speedshift
Benz's AMG Speedshift transmissions are geared for sporty performance. They can select and keep the optimal gear for the current drive situation, such as when taking sharp corners.
CVT (Continuously Variable Transmission)
The CVT, or continuously variable transmission, can change through a never-ending range of gear ratios, as opposed to other transmissions that only offer a limited number of gear ratios in fixed steps. This allows it to achieve better fuel efficiency and acceleration.
Dual-Clutch Transmissions (DCT)
Many Benzs make use of dual-clutch transmissions. The DCT is essentially a combination of two manual transmissions and two separate clutches in a single gearbox. It is capable of higher fuel efficiency and smoother gear shifting than traditional automatic and manual transmissions.
Maintenance & Care of Your Mercedes Benz Transmission
Benz transmissions are built to last, but that doesn't mean you should skip any care and maintenance altogether. You can get the most out of your Benz's transmission by sending your vehicle for its scheduled maintenance, which should include transmission fluid checks. When driving, ensure that you're in the correct gear (that means not leaving your manual transmission in low gear for too long) and that you warm up your Benz before driving so that the oils flow correctly. Make sure that your tires are not overly low, as driving on them can put unnecessary strain on your transmission. Finally, your Benz's cooling system is also responsible for cooling the transmission fluid to an appropriate temperature, so make sure it is in good order.
Common Issues & How to Address Them
Transmission issues are frustrating and, most of the time, require a trained specialist to remedy them. These include delayed shifting, slipping gears, illuminated check engine light, burning smells, strange noises, and fluid leaks.
Occasionally, as with the case of burning smells and strange noises, the cause might be low transmission fluid or coolant levels. While you can check and top these up on your own, it might be all too late, as your transmission may have already incurred damage. In such cases, repair or a whole transmission replacement might be necessary.
Are Mercedes Benz Transmissions Expensive?
As with all luxury car parts, Mercedes-Benz transmissions will cost more than average. One way to avoid spending more than necessary is to opt for used transmissions from a trustworthy dealer.
