2006 Mercedes-Benz E350 Q&A
2006 Mercedes-Benz E350 Question: What would cuase my transmission to just stop working in all gears?
My transmission stopped working in all gears including reverse. No leaks or noise just driving down the road and it went out. Just like it was in neutral. I have never had any noises or leaks and it has always shifted normal. Could there be an electrical problem or some kind of module that needs to be replaced? - michael001
check connection to tranny. maybe dirty or just disconnected. if connection is good than have diagnostic run to see what issue is. bring to tranny specialist for this. more thorough test. - arturo08
scan trans codes poss electrical issues or blown fuse controlling the tcm - globalhelper
If there was an electrical problem, the transmission would go into failsafe or "limp" mode. It would still move in drive or reverse at low speeds as long as the transmission is full of fluid (you need a special dipstick tool to check fluid level). Are there any warning messages? If it doesn't move at all then there is either an internal mechanical problem or internal leak between the valve body and the transmission case. I am very familiar with these transmissions and have the Mercedes diagnostic system at the shop. It may or may not be a simple fix but I would be happy to give you my opinion before you spend a bunch of money to repair it. Feel free to contact me at the shop. Thanks.
