722.9 Conductor plate failure
Hello everyone. I have a 2007 E550 with the 7spd tranny with 147k miles on it. I’ve been daily driving it the last year or so, and lately it’s been giving me transmission problems. I’ve pulled codes which were “input/output speed sensor intermittent”. Every now and then I’ll be on the freeway and my car will just slip into neutral, was always fixable by shutting the car off and restarting it, but tonight it went into limp mode after a kickdown when I passed a car and stayed in limp mode and I couldn’t get it out of 2nd gear. Is the conductor plate really the problem here? Don’t want to have to spend $900 on a new conductor plate if that isn’t the problem but the symptoms Im having point to a faulty conductor plate. Help?

The 7gTronic tranny does not use conductor plate. They are common on the 5spd tranny. You might have some issues somewhere either electronically or could be an issue with transmission but they are generally very reliable however the service on the tranny are seal which should be performed by your local MB dealer since they have to change it from the pan and filled through the pan with a equipment that runs the fluid.
