If your transmission is vacuum controlled, some simple diagnostics with a Mity Vac might get you some good advice from this forum.

In reality, most of them are not "specialists". Very few shops actually understand the tuning of a M/B transmission. Their natural response (and the one that generates the maximum amount of money for them) is............"you need a rebuilt transmission".

Sadly, even their supposed "rebuilds" vary across the map as to exactly which parts they put into it. Many times, the box is not completely rebuilt and it won't go more than 50K before additional issues develop.

If you do decide to get a rebuilt, these fellows have been doing M/B transmissions for 25 years and have a good reputation:

rebuilt remanufactured mercedes benz automatic transmissions


I would NEVER allow the local yokel to rebuild it. You're just tossing away good money.

Thanks for the info!

Sounds cheap. If I was set up to swap a transmission and I could find a good supply of 722.435s, then I could just burn through used ones.

Maybe I will clear out the garage and ask for more tools for Christmas.

Thanks!

The 2-3 flare is quite common on these transmissions- I recently cured mine on my 'new' E300D by installing the K1 spring kit- it's a $10 or so part from the dealer, Mercedes call it a thrust pin. It's slightly modified from the original part.
It's very easy to replace and can be done with the transmission in-car during a fluid/filter change. Changing that and a fluid/filter renew has totally smoothed out the 2-3 change on mine.

The part number is 126 270 44 77

The rear-end thunk is most likely the diff mount rubber bushes or rear subframe bushes. Not a massive deal but fairly easy to replace for a garage if it bothers you.
