[W126 Coupe] MBCOUPES Digest, Vol 89, Issue 18 reverse noise

[gary ensor]

Mel,
  The cause of slow engagement to reverse is usually the reverse piston lip seals in the 722.3 trans., that may be why the lucas additive worked for someone else answering your question, by softening the rubber lip seals. If it goes long enough slipping as it goes to reverse you are wearing the k1 clutch pack friction discs, which will start causing a rotating metallic noise when backing up, and eventually loose reverse all together.

> Check your transmission fuild level. If that's good I had the same issue. The answer for me was shifting from d to r a couple of times. Which subsided the engagement of reverse. I ended up taking to dealer, they said new tranny. I decided for 10 bucks I try some Lucas transmission fix. That was 5 years ago which fixed the issue. I'm almost sure it was a sticky piston. You could at your own risk try it. As most people claim its snake oil. You can get it at any auto parts store. Just make sure the transmission is good and hot when and if you decide to do it. The stuff pours like honey but once mixed with fluid thins out.
