if you do a search under 722.6 transmission you'll find a widely agreed upon figure of fifity thousand miles. expect something in the four hundred dollar range, and make sure either a dealer or mercedes specialist shop works on the gearbox. you can also think about an oil analysis from the drained oil to get some detailed info on the box.
I think the latest edition of Mercedes Enthusiast Magazine has an article by LJK Setright of Mercedes transmission, I haven't read it yet.

No transmission service is recommended on the 722.6, I don't recommend it, not until probably over 200,000 miles.

Yeah, you're 1998 has the 722.6, so something is wrong in regards to the spec for a 60,000 mile trans service. MB never recommended a 60,000 trans service that I am aware of anyways, so something is wrong here. They went from 30,000 to lifetime. Is the spec you are quoting possibly out of some literature the DEALER put in the paperwork, not Mercedes??

That trans should be serviced! Don't listen to MB about lifetime fluid, there isn't any such thing! If the trans is serviced it will LAST 200K to 300K.
WE (dealer) have replaced/repaired at least 2000 of the 722.6 transmissions in the last 2 years! Spend the money.

And in this corner...
This is where I would like to fly to Germany, find the 722.6 engineering team, and throttle them! Service it, don't service it. "Life" means what? Life of a lease, or life of the rest of the car? Crap.

Rotating Torque Converter
Quote:
What is the best procedure for rotating the torque converter to access the drain plug. e.g wheels off the ground...27mm bolt to rotate engine...transmission placed in park or neutral? etc. Thanks

If it's resettable, it would be done with the shop computer. I doubt it's resettable. It was evidently just on earlier transmissions for engineering purposes.

I do prevenative maintenance on HD equipment for a living in my opinion it would not be anything but benificial to service the tranny at least every 50k.
I just did mine at 54k with 7.5qts of Pennzoil Multi ATF and it's been operating superbly.
