My 2004 e500 is doing the same thing...maybe 3-4 times now. How did you resolve your problem? - cbock
I am currently having the same problem with my E500. The diagnosis appears to be a faulty valve box (not sure if the part name is completely correct)according to my transmission specialists. This particular part is conjoined with a computer, I guess that controls the trans - priced at $1300. Not totally sure as I have been waiting to get my car back for almost a week now. My mechanic who bought the part from a local dealer is now having to wait for them to program the part, and of course it is not a priority for them as they are not replacing the part. I am very frustrated with this car; just a few months ago I had to have the computer programmed ($200) because the car was downshifting with a hard thud. Hope this helps! - cbanko

i think that the problem is the transmission conductor plate and this is one of the main part in most of mercedes trans that go bad.BTW a have the same problem with my c230 2003.most of the time those stupide mecanic will tell you that you have to replace the trans.a understand that it is not their fault because of the economy but diagnos first and then proceed. - Visitor
Hi guys , here with a little insight on these units . The transmission computer is parts of the valve body inside the transmission and it has to be serviced by replaceing both parts as one . the most common cause of transmission problems are speed sensors, the case connector where the wires go into the transmission transmission fluid will leak out into the harness and make it way to the module under the dash , when the fluid gets into the harness it will start to ground out everything in that harness and make the transmission go into limp mode/fail safe . If you turn the key off and back on that will reset the problem until the computer sees a problem again and then it will start over again , but when this happens it has set a code for a problem . the update for this is cheap and would only take a day to install . If any one has anything I could help with we dont mind helping people in these tuff times . - expert

Also, do you guys know whats transmission version on 2005 MB E500 V8, regular? Is it 722.6 or other?
The electrical connector at the automatic transmission may leak fluid into the wiring harness...
High mileage vehicles may develop a leak from one or more of the transmission oil seals.
