06 E350 Not Shifting
Had a problem that started yesterday, noticed the car would not shift from lower gear to next gear - even using the manual shift to Upshift/Downshift. The other thing we noticed when this happens (it started as intermittent) the Sport/Comfort selection does not work and the indicators do not show up mext to the odometer.
Another odd symptom that occurs with the non-shifting, the gear shift lever cannot be moved from Drive to Park without turning the ignition off, then back on. Is this something the small battery in the engine compartment controls? Thanks, LarryT |

Looking at the info available to me there is a high likelihood that this issue involves a problem with either the transmission control module or the transmission itself. That said, it's not worth jumping to conclusions just yet.
Do you have a means of checking transmission fault codes? I'm willing to bet there's at least one fault code stored that could help identify the problem... |

Are the trans codes located in a different place than the rest of the codes? IOW, if I ask them to pull the codes will they need to go to different locations to plug in? (I gotta get rid of this car - but it may have to go to Salvage at this point) TIA, LarryT |

Plug it in at same place but read all the codes, not just the engine code. The reader (if right one) will allow you to read all codes.

Transmission fault codes can be checked from the same port as any other codes, however, a basic code reader that you buy at a parts store likely won't be able to do it.
Most codes readers aren't capable of reading any codes or sensor information beyond what is required to be available by law for emissions testing. Transmission codes fall outside of that so they are typically addressed in the CAN system at the free will of auto manufacturers and the addressing is different from manufacturer to manufacturer. It's possible you can check them with something like the Carly app or with a paid add-on to the Torque app (I haven't looked for one for Mercedes yet) through a bluetooth OBD2 CAN module. There are also probably some consumer OBD2 readers available that can be used for Mercedes specifically (that may or may not be available for a reasonable price). Otherwise you could see if a repair shop will read the codes for you (cheap or free preferably). A long time ago, in my quest to save money by repairing my own vehicles, I made good friends with a couple guys that own a repair shop in town. When I need to I go down to their shop and use their $50k worth of computers/software to do what I want. I realize that this isn't available to the average guy on the street but...that's how I get this info for myself. It's only cost me a few drinks to earn that privilege. |

OP, do you have 4matic or not. The rwd and awd had completely different transmissions. If you have rwd you have a 722.9 transmission where the TCM is built into the conductor plate. It's going to get expensive. If you have 4matic you have the good old 722.6. Your pronosis is much cheaper. Either way you need an MB specific scanner tool.

That icarsoft MB2 looks to be pretty badass. I just might get one for myself if the Carly app is as terrible as everyone says it is.

So, I need to make some decisions. I also need to find a local Auto Trans. to run the codes. One thing I've noticed (especially around here with MB's) is they tend to go with the "better replace it" with "it" being any kind of repair. I could take it to the MB dealer - they've always treated me well. But that's a long way to drive in 1st gear. It's roughly 30 miles. Thanks for the suggestions. LarryT |

Not sure about Op but my 2006 E350 is AWD. I should have mentioned that when I started this thread...
Thanks -- LarryT |

Forgot to ask, when you say "Shifter Failure" are you talking about the Shift Handle we move to select gears?
Is the Linkage Shifting a mechanical control or electronic/electrical? TIA |

Ok so you have a 722.6 5spd, you're in luck. Find an independent MB shop.

Ok, it appears I have a 722.6 - when you say "much cheaper" - what kind of price are you talking? $1000 or $10000. much cheaper means different things to different people. TIA... |
