Just to update the 722.6 transmission file, MB now subs all parts directly related to the planetaries to a full planetary assembly, taking all the options out of rebuilding. After you pay more than $2K for that part/assembly alone, then a few other necessary updated parts, you may as well just buy the transmission from Benz; there's too many other parts that can go bad in that transmission to justify saving a few 100 dollars on an aftermarket rebuild. Be careful with used parts; remember, you're replacing fatigued and failed parts with known defective parts, and you're just looking for trouble unless you just want to unload your vehicle. This absolutely sucks, as this was a most enjoyable transmission for me to rebuild.
