Last Updated on October 31, 2023 by Robert Wilson

Mercedes-Benz is known for its luxury vehicles and advanced engineering, but even the best can have issues.

Some Mercedes-Benz models equipped with a 5-speed automatic transmission have been known to experience problems. These range from minor issues like hesitation when shifting gears to more serious problems like complete transmission failure.

In some cases, these transmission problems have led to class action lawsuits. If you own a Mercedes-Benz with a 5-speed automatic transmission, it’s important to be aware of the potential problems and how to get them fixed.

The most common issue is the transmission slipping or not engaging properly. This can be extremely frustrating and dangerous, as it can cause your car to stall in traffic or even lurch forward unexpectedly.

Other issues include the transmission jerking or hesitating when shifting gears, and the check engine light coming on. If you’re experiencing any of these problems, it’s important to take your car to a qualified mechanic or dealership for diagnosis and repair. In some cases, the problem may be covered under warranty.

Is Mercedes Automatic Transmission Reliable?

Mercedes-Benz is a German automobile manufacturer with a long history of producing high-quality vehicles.

The company’s cars are known for their luxurious features and cutting-edge technology, and their automatic transmission models are no exception. Mercedes’ automatic transmissions are some of the most reliable on the market, thanks to the company’s commitment to quality engineering and strict testing standards.

Whether you’re looking for a sedan, SUV, or sports car, Mercedes offers a wide range of vehicles with different engine and transmission options.

And while all of the company’s products are built to last, their automatic transmissions are particularly renowned for their durability and performance. Whether you’re looking for a 7-speed or 9-speed gearbox, Mercedes has an option that will suit your needs.

Of course, like any complex piece of machinery, there is always the potential for something to go wrong. But if you take good care of your vehicle and have it serviced regularly, you can expect your Mercedes automatic transmission to provide years of trouble-free operation.

How Long Does a Mercedes Auto Gearbox Last?

A Mercedes-Benz car is equipped with either an automatic or manual gearbox. The lifespan of a gearbox depends on various factors such as driving habits, terrain, maintenance schedule, and whether the car is used for commercial purposes.

The average lifespan of an automatic gearbox is around 150,000 miles while that of a manual gearbox is around double at 300,000 miles.

However, it is not uncommon for owners to get over 400,000 miles out of their manual gearboxes with proper care and maintenance.

How Long Does a 5 Speed Transmission Last?

The lifespan of a 5 speed transmission depends on a number of factors, including the quality of the transmission, the type of vehicle it is in, and how well it is maintained. In general, however, a 5 speed transmission can last anywhere from 100,000 to 300,000 miles before requiring replacement or major repairs.

Why is My Mercedes Transmission Slipping?

If you’re experiencing transmission slipping in your Mercedes, it’s likely due to a fluid leak or low fluid levels. There are a few other possible causes, but these are the most common. Transmission slipping is when your car seems to be shifting gears on its own.

It can be a scary experience, especially if you’re not sure what’s causing it. Slipping can happen when your car’s transmission fluid is low or leaking. If the level of fluid gets too low, it can’t lubricate the transmission properly and parts start to wear out prematurely.

A leak can also cause the same problem because it allows air to get into the system which can cause gears to slip. If you think you might have a problem with your transmission, the best thing to do is take it to a qualified mechanic for an inspection. They’ll be able to diagnose the problem and tell you what needs to be done to fix it.

In most cases, simply topping off the fluid levels or fixing a leak will solve the issue. However, if there is extensive damage, you may need to have your transmission rebuilt or replaced.

If you have a 722.6 transmission, also known as a Mercedes-Benz 7G-Tronic, you may eventually experience one or more of the following symptoms:

1. The “check engine” light comes on.

2. You notice reduced power and torque when accelerating.

3. Your transmission is slipping out of gear, or feels like it’s “hunting” for the right gear. 4. Your transmission fluid looks dirty or has a burning smell.

5. There is a knocking noise coming from the transmission area.

If you’re experiencing any of these issues, it’s important to take your car to a qualified mechanic as soon as possible for diagnosis and repair.

In some cases, the problem may be something as simple as low fluid levels or dirty fluid that needs to be flushed and replaced; however, it could also be indicative of more serious damage to the conductor plate, clutches, or other components within the transmission.


If you own a Mercedes Benz with an automatic transmission, you may have faced these annoying issues.

The most common problem is the transmission slipping or jerking when it’s cold. This can be caused by a variety of things, but the most likely cause is low fluid levels.

Another problem that can occur is hard shifting, which can be caused by a dirty filter or incorrect fluid levels. If you’re experiencing any of these problems, it’s essential to take your car to a qualified mechanic for diagnosis and repair.
