As I have posted in the past, DB has changed their mantra about the "sealed for life concept", on the new vehicles which have the 722.6X transmission.
Not to re-hash an old topic of "change or don't change", but this post is just meant for those who DO believe in changing the fluid. My target has always been 40,000 mile intervals.
I AM IN NO WAY PROMOTING GOING AGAINST WHAT IS IN YOUR OWNERS' MANUAL. YOU DO WHATEVER THE SPIRIT LEADS YOU. YOU MUST CONSIDER THE POSSIBLE REPERCUSSIONS SUCH AS WARRANTY VOID, ETC.
ONE NOTABLE THING ABOUT THIS PROCEDURE IS THE STRICT ADHERENCE TO "SURGICAL-LIKE" CLEANLINESS AT ALL STEPS, AND METICULOUS CARE TO NOT OVER OR UNDER-FILL THE TRANSMISSION. APPARENTLY, THESE BOXES ARE VERY SENSITIVE TO ANY DEGREE OF CONTAMINATION OR IMBALANCED FLUID LEVELS. IF YOU OVERFILL, YOU NEED TO SIPHON OUT EXCESS.
I opted for the "new" type fluid, designed for the new 7-Speed boxes. I had a long discussion with one of the engineers at MotherShip Montvale, who confirmed that the use of the "New" fluid- A.001.989.45.03.10 (which is also only 1/2 the cost of the "old" fluid A.001.989.21.03.10) IS ALLOWED!!
The usual CYA blah, blah stuff. I am not claiming any expertise. I make no bones about it, I am a novice mechanic. My projects are based on my interpretation of the WIS procedures, and/or outside sources. Do work at your own discretion.
G-AMG, you're destined either for sainthood or defendant-hood...
Seriously, thanks for another addition to our DIY sticky.
I would point out for those wishing to follow this procedure, don't shortcut it. You have to measure the fluid level accurately and at the proper temperature. And cleanliness, and all the other warnings G has supplied.
Also, note that if you have a post 99 MY 722.x transmission, you won't have a drain plug on the converter, so you'll only be able to change out approximately 1/3 of the fluid unless you pick a way to flush out the cooler/converter/cooler lines.
Take care and enjoy the ride,
Greg

This is interesting and is probably a smart move.
I understand that the new fluid can be used in the 5 speed tranny and not the other way around. Most likely the new fluid is better than the old fluid. However, drain and fill does not drain all fluid, now you have the old and new fluid mixed in the tranny. Will this be okay?
Thanks for the DIY, however, your W210 is a 98 which suppose to have a torque converter drain. Why don't you drain your converter also?
I know it's your DIY but would mixing old ATF and new ATF not very beneficial?
Anyway, does your transmission shift better afterward?
When you say "break off the tab and pry up the clip (make sure to catch the remaining piece)", do you have to worry about it falling into the tranny, or just into the engine bay?
1. No, for some reason my '98 does NOT have a drain bolt for the Torque Converter.
2. It is MY UNDERSTANDING after speaking with Mothership, that it is not a problem mixing the old and the new.
3. The MB techs I have spoken to say their standard change is just a pan drop, filter change, and 5 liter fluid change. Yes, SOME advocate a system flush, but apparently has it's own set of dangers, mainly having the pressure "dislodge" material from the old hoses, etc, which will quickly kill your box. Yes, there will be roughly 2.5 liters still "in the system", but that is what is done.
4. No, the safety tab piece will not fall into the trans, just into the engine compartment.

Excellent DIY!
I did the transmission oil change last month and there was no drain plug for the torque converter. My car is a 1998 E300 Turbo-Diesel.
I just drained the ATF on my 2001 E430 4 matic a few days ago mixing the new 7 speed ATF with what ever was in there before and have driven ~100 miles with no difficulty. The only hangup I had doing the change was when I replaced the pan, the front passenger side portion of the pan got a little tangled on the metal frame thing and left a gap I didnt catch until I poured 2 L into the system. A expensive puddle formed on the ground. No worries though because I bought 2 L extra and managed to catch about 1 L of the fluid in a bucket. Great DIY, wish I had it a few days ago
