No Reverse 95 S420 722.366

Last night, pulled into neighbor's driveway, put her into reverse to back into my garage and nothing. All forward gears work fine, flawlessly, actually.No indication of failing bands and clutches.

I've spent the better part of my morning reviewing threads and pdf's relating this common problem with the reverse seal tearing or o ring in valve body? Service bulletin says check plates and sealing rings on brake B-3 piston...

309,334 original miles on the drive train. I suspect the seal finally wore out.

Please throw some opinions over here.

I found this: Mercedes Mechanic had the PDF posted. I'll drop the pan, pull valve body and inspect.

Thanks for the response. You're the one who wrote that you drive yours around town without reverse in one of the threads!

I can hear it going into reverse but're 100% set on pulling it apart? Even before dropping the valve body? I'd like to get this resolved this weekend.

Mercedes Mechanic seems to think valve body first then R&R.


BTW, I live in Livermore. Small world man. Sent you a PM. I downloaded everything and printed it out the other day.
