Mercedes Transmisions


Mercedes is known for its premier luxury vehicles. They have continuously produced very reliable well-performing cars over the last few decades. The Mercedes manufacturers are constantly finding new ways to transform their vehicles to make them even better. Their automatic transmissions have continued to evolve and become better each year. They know how to build reliable transmissions that anyone can count on.


In the early 2000s, some of the Mercedes vehicles were built with a 722.6 transmission. You might be wondering what exactly is this? This is a 6-speed automatic transmission with 2 internal sensors. These sensors are used to monitor all of the functions that communicate to the transmission. Any issues with the clutch or the gears are communicated through these sensors. They trigger codes that will then inform the transmission system. These codes are very important because they help give valuable information when diagnosing any transmission problems. 


In the more recent years since the 722.6, Mercedes has developed a new transmission called the 722.9. So, what is different with this transmission? This is a 7-speed automatic transmission that has 3 sensors to monitor all of the functions. Additionally, the transmission control module is inside the transmission. This is a great improvement because it is a part of the valve body instead of being a standalone unit outside the transmission. It will be able to relay more accurate data being inside the transmission.  


This is also a very notable change because the TCM is now programmed with the VIN when the car is manufactured. Why is this a good thing? This is good because it means it can not be rewritten with another VIN. The VIN needs to match the 722.9 transmissions and if it doesn’t, the vehicle won’t even start because it won’t recognize the module. This means that there is a special way to repair these types of transmissions.


The only way to correctly repair a 722.9 transmission is to rebuild it with a new valve body as well as a TMC that can be programmed to the exact vehicle. As you can imagine this is not an easy task and requires a very highly trained professional to rebuild the transmission system correctly. Not only do the mechanical potions need to be rebuilt, but they all need to be reprogrammed as well. If you need a Mercedes transmission repair, you need to find a trained professional who knows who to mechanically repair a Mercedes transmission as well as reprogram the entire thing. 


What Are The Symptoms Of A Faulty Mercedes Transmission?


There are many different symptoms that will tell you that you have a failing transmission. It is important to be aware of these symptoms so you can get your car fixed as soon as the problem arises. You know your car the best since you drive it the most, so if you notice it driving differently or making weird noises, you should always get it checked out. It never hurts to have a mechanic run diagnostics to ensure everything is working properly or to diagnose a problem. If you are experiencing transmission failure, you will notice some signs that will alert you to get your car looked at.


One of the most common symptoms is your transmission not staying in gear. When this happens, you will notice your car won’t move forward or your gears will start slipping. If this happens, you will be able to feel your car shift from one gear to the next. This will happen out of nowhere. Another common symptom is leaking transmission fluid. If you notice red fluid under your car, you will want to get it looked at immediately. If fluid leaks all over the transmission system, it could cause a lot of damage. 


If you ever smell sometimes burning coming from your car while you are driving, take it to your local repair shop immediately. This is a sign that your transmission is failing. This could happen if your transmission fluid levels get too low from a leak. Lastly, if you hear a buzzing or clunking noise coming from your car, this could be coming from your transmission. This noise happens when your gears are damaged. Always take your car into your local repair shop the moment you notice any of these problems. It is important to get them fixed as soon as possible or you could be facing an expensive Mercedes transmission repair. 


Mercedes Transmission Problems


Although Mercedes has built up a reputation for producing very reliable cars, their transmissions do have issues at times. It is important to be aware of some of the common transmission problems you could face with your Mercedes transmission. Some of the most common Mercedes transmission problems are excess valve bodywear, solenoid failure, low fluid levels, mechanical failure, and torque converter failure. 


If your car’s solenoids malfunction, you will face transmission problems. The solenoids are electromagnetic switches and they are responsible for specific functions of the transmission. These switches control which gears need to be selected in the transmission. They also are responsible for determining how much pressure needs to be applied to each gear shift. This is a very important job so the transmission can operate the car correctly and run smoothly. As you can see, these solenoids are very important to the function of the transmission and if they fail, you will notice problems. 


If you notice that your solenoids are failing, you will need to have your transmission diagnosed as soon as you notice gear shifting problems. If you let this problem go on for too long, there will be more internal damage to your transmission. Another problem you could face with your Mercedes transmission is with the valve body. 


The valve body is a part that is responsible for managing the fluid flow rates and adjusting them when necessary. This part ensures there is transmission fluid flowing throughout the entire system. Unfortunately, these valves do wear out over time and could cause fluid to leak into bad areas. This will affect the car’s ability to shift correctly. If you just need to replace the valve body, you can do this without removing the whole transmission. 


Another problem that you could see with your Mercedes transmission is an external transmission leak. Typically, this happens due to worn out parts. These parts are constantly working to ensure the transmission works correctly so they do eventually wear down. If you notice that your car is leaking transmission fluid, you will need to go see a mechanic as soon as you can. This could lead to some very bad problems if you let it persist. This could overheat your transmission and eventually damage the entire transmission. The fluid is crucial for keeping the working parts lubricated and keeping the system cooled off. It is important to get your transmission leak fixed as soon as possible. 


If your torque converter fails, you will most likely be facing a complete transmission rebuild. This is because the torque converter is a crucial part of the system and when it fails, the transmission will be contaminated with fluid. This causes very bad problems. The solenoids will fail due to the fluid as well as valves will start to stick. If fluid leaks throughout your system, the transmission will be damaged and need to be rebuilt. 


Lastly, your transmission’s internal mechanical parts will start to wear out over time. These parts include springs, planetary gears, clutches, pumps, and bearings. These can all fail due to overuse. If this happens, your Mercedes transmission will need to be removed from the vehicle so the failing part can be replaced. The entire transmission needs to be removed for this to happen. Depending on the location of the part, a mechanic might suggest doing a partial transmission rebuild to fix the problem. 


How To Repair My Mercedes Transmission?


If you think you need a Mercedes transmission repair, you will want to get a proper diagnosis from a specialized mechanic. They will be able to determine where the problem is coming from and inform you of what they need to do to fix it. They will also be able to give you a price estimate so you can financially plan for this costly repair. 


It is important to note that a Mercedes transmission repair is a lot different than other transmission repairs. If your Mercedes has a 722.9 transmission, there are some special requirements when repairing this transmission. This is because the TMC is programmed with the VIN. This means that the VIN can’t be rewritten so it needs to match the transmission. If it does not match, your car will not start because it won’t recognize the module. So, the only way to correctly repair a 722.9 transmission is to rebuild it with a new valve body and a TMC that can be programmed to your specific vehicle. Since there are very specific requirements for this repair, it is best you take your car in to a trusted mechanic and let them repair your transmission.
