1994 e320 Reverse Clutch Replacement (im gonna do it myself.. i think)
 

:book: Does anybody have detailed instructions or a manual i can download on the replacement of the clutches in my 722.3 transmission? I have no problem getting the transmission out of the car but from then on I need some instructions. The car is a 1994 e320. I have tried searching the info but have not found specifics. Are there any special mb tools I will need once inside the transmission? Thanks in advance for your help. You guys are the best. benjay

PLEASE take/post LOTS of pics of this process. I'm sure I'll have to do it someday on my E320 and would love to see how its done.

Sure thing! I just need someone who can email me a copy of the tech sheets for this procedure. I can do anything with instructions im just hesitant to rip open the trans without.

Could Someone Email Me The Directions For Reverse Clutch Replacement On My 1994 E320?
 

I NEED THE WIS OR SOME KIND OF MERCEDES INSTRUCTIONS ON REPLACING THE REVERSE BANDS IN MY 1994 E320 AUTO TRANSMISSION. i HAVE NO PROBLEM GETTING THE TRANS OUT, JUST NEED INSTRUCTIONS FROM THAT POINT! IF YOU CAN HELP I WOULD BE GRATEFULL OR IF THEY ARE ALREADY POSTED SOMEWHERE COULD YOU SEND ME THE LINK!!! I WOULD BE GLAD TO TAKE PICTS AND DOCUMENT THIS PROCESS FOR EVERYBODY ELSE THAT IS GOING TO HAVE TO DO THIS REPAIR! THANKS BENJAY

first of all who diagnosed that reverse clutches need to be replaced? it is not a hard job once the trans is out.too long for e mail but call me and i can walk you through it.

I have come to that conclusion based upon reading numerous other peoples accounts on this forum of the same problem with the same car.

Symptom: Transmission works flawlessly. Reverse is there one second and gone the next. All forward gears work as does park. just no reverse. Linkage is ok.

Everybodys whos posts I have read have opted to have the job done by someone else. Is it really THAT hard? I can understand the normal joe not wanting to rip the trans out because it takes a while, but thats no big deal to me. Just once the trans is out and on a bench Ill need some instruction. I was also wanting to know of any special tools I might need.

Considering the amount of people that have reported this problem on this forum, This is a very common thing for these cars. Mercedes must have published some bulletin or repair info for their techs to guide them thru this procedure.

this is not necessarily the reverse clutches causing this problem.if it was you would have reverse but it would slip when trying to use it.there would appear to be a problem with the reverse piston from your description.this could involve taking apart the front pump assembly which contains that piston and replacing two or more seals.it will always be a good idea to replace the reverse clutches when in that far but i dont think it will fix your problem by itself.

thanks for the input . What you say makes perfect sense. I have just heard that the piston sticks which causes the reverse band to snap eventually. Either way you are correct because I will probably want to freshen up some other things while in there so I dont have to rip this thing out again soon. Do you know if mercedes makes a rebuild manual for this trans and how i can get ahold of one?
