At one time Mercedes-Benz was part of the Chrysler family of companies and they shared the transmission for use in many Chrysler products Magnum, Challenger, Charger and a few Jeep applications, too. And I appreciate the timely manner in which it was done. I went in for a transmission fluid exchange and a standard oil change, but Jim did much more than that.
Your comments please, about the following. This place deserves 7 stars! When the solenoids perform outside normal parameters it can cause clutches to engage and disengage incorrectly which quickly destroys them. Tune your transmission for Peak Shifting Performance: After all the above are taken care of, only then you will be able to fine tune your transmissions shift patterns for optimum performance. This allows the transmission operation to adapt to different driving styles and demands. My car runs and drives great. I bet you would be pretty hard pressed to find anyone here that changes their 722. Transmission abuse will lead to excessive heat buildup and if not kept in check, will quickly destroy the transmission.
Gear train failures have been greatly reduced in later model transmissions due to a high tech computerised fail safe systems. It turns out the balance shaft is broken. Of course, this requires a rebuild facility capable of not only rebuilding the mechanical portions of the transmission but programming it as well. All issues with your Mercedes transmission, manual or automatic, need to be addressed. Second, the transmission control module is inside the transmission as part of the valve body instead of being a standalone unit outside of the transmission. I highly recommend his work.

To correct this problem, the conductor plug must be replaced, the wiring harness must be cleaned of excess transmission fluid, and the transmission control module should be disassembled and sprayed clean with electrical contact cleaner. While parked on a hill and attempting to place the gear shifter into reverse, the vehicle would roll forward instead of backwards. By keeping the fluid clean and using a transmission additive you can push more life out of a dying transmission. We took it to the dealer and it was diagnosed with a balance shaft error. Thanks Jim for going extra mile. The price was way different then what I was paying with Mercury. Jim and his crew were very helpful.
Permanent internal damage can be avoided if the leak is caught early and a new conductor plate is installed, and the proper fluid level is re-established. If continued driving occurs with this condition internal damage will cause failure requiring a complete rebuild. In most cases the transmission control module will revert back to proper operation, but in some cases it must be replaced. One of the common areas is where the external wiring harness plugs in to the transmission. I don't believe that is the true problem. The vehicle was not repaired for the failure.

Occasionally Mercedes Benz transmissions will develop external transmission leaks. Car would come to complete stop and then would start moving again. Transmission Computer Electrical Problems All 722. Repair of this component is not feasible, so the part must be replaced with a new one produced by the manufacturer, available from the Mercedes dealership. There is an information blackout on the subject yet piecing together the with our warranty data we can see that many defects of the sensors in the transmissions cause total gearbox failures while driving.
How long does it take to engage? No repairs have been performed. I felt it was very serious as I was on interstate when it would suddenly stop in traffic. The dealer could not determine the cause of the failure. Electrical Valve Body Conductor Plate Sensors A defective transmission conductor plate is generally diagnosed by the speed sensor codes it produces when it has failed. Macintosh is aware of the problem and its serious nature, but refuses to return my calls. This will affect shift quality, feel and timing. I told him that I might be getting a new can in a year or two, so he just did the necessary work.
