AMG GT transmission problems

My 2015 Mercedes AMG GT gasoline engine is acting up The automatic transmission seems to think Park is optional The engine sometimes refuses to start, the check engine light is on, and the gearbox is slipping There's also an error code I suspect a defective control unit Anyone else run into this transmission failure

I know exactly what you're going through I had a similar experience with my AMG GT The symptoms you're describing sound eerily familiar When mine acted up, it also felt like the transmission issues would cause unclean shifting I would be very interested to know if you have checked the transmission sensor as that was the issue for me Have you had the car scanned for specific error codes Knowing those would definitely help narrow down the possibilities before you start replacing parts

Thanks for the reply I appreciate knowing I'm not alone in this AMG GT transmission misery I scanned it, and it's pointing towards the control unit, but I'm skeptical of just trusting the codes blindly When you say 'transmission sensor', was it throwing a specific code related to that, or was it more of a process of elimination for you Also, did your symptoms come on suddenly, or was it a gradual decline Trying to figure out if I should brace myself for a full-blown transmission failure or if it's something simpler

In my case, there was a specific code related to the transmission sensor, but it wasn't immediately obvious that was the root cause There were other related codes as well The symptoms did come on relatively suddenly One day it was fine, and the next, I was experiencing the same issues you're describing Given your symptoms and the error code pointing towards the control unit, it's probably best to take it to a qualified workshop for a proper diagnosis They'll be able to test the control unit and the transmission sensor to confirm the issue before you commit to any expensive repairs Replacing the control unit without proper diagnosis could be a costly mistake

You were spot on Took it to the workshop, and after some digging, it was indeed the control unit acting up, just like the error code suggested Replaced it, and now it's shifting well It cost me around 1000€, just as I feared Thanks a bunch for sharing your experience; it definitely helped me prepare for the worst and not lose my mind completely I appreciate the advice about checking the transmission sensor and suggesting a workshop This transmission failure had me really stressed
