I am going to attempt to remove my transmission for the first time with no prior experience. If anyone can spare any type of "how to" manual or advice pertaining to its removal it would be greatly appreciated.
Background: The transmission seems to leak periodically and is getting progressively worse. Recently I found trans fluid on the floor of my driveway. When I went to go pick the car up I found that the mating surface btw the engine and trans was wet (with trans fluid) so I did a bit of research and found that the trans o ring for the transmission fluid pump is known to wear out over a relatively small amount of time. I am almost certain that my problem lies therein so im going to try removing the trans off of my junker e320 (same year) and putting it on my daily driver.
Before I answer your question let me add that prior to my purchasing the car, the o-ring on the trans connector was replaced (along with the connector itself) and the conductor plate was replaced, both by a Mercedes dealership. Now, I found my information by searching for the symptoms I was experiencing on google, watching a good number of videos from people that seem to know what they're doing, namely a guy with the you tube channel "mercedessource," and reading up on some TSB's on 722.6 tranny problems and what cause them. I have no experience on rebuilding transmissions myself so I guess I cant really say if it is for sure the o-ring on the pump housing but from what info I have gathered, my diagnosis seems like a logical conclusion. There is also an oil leak, likely coming from the rear main seal (crank seal(front), valve cover gasket I replaced less than a year ago) which I wiped clean then retook a picture of the next day to distinguish it from the trans fluid leak.
mercedessource's Kent B is pretty good. MAVA on the other forum is at the
'expert' category. be mindful of your own limits, however, as there aren't
many people tackling a R&R of a transmission for good reason. you're
relying on a bit of luck. the penalty for failure can be high and much time
troubleshooting and going back to open the patient
at one time, someone posted a 93 page PDF of the complete 722.6 transmission
manual published by ATSG on the web (various MB forums)... until concerns of copyright protection
prompted their removal. You may want to either buy a copy or to see if a
pirated copy still exists, though would be very challenging to find.
Something doesn't look right. That doesn't look like a 722.6 and it doesn't look like a 210 chassis. Look at the photo from a 1999 E-Class - a 722.6 in a 210 chassis. If you don't know what you have you really should take the job to a shop. And if the photo is an anomaly - I've done several of these R&R's. You REALLY need to know what you are doing to do the job right - and SAFELY.
