01 e430 rought shiffting tranny
i also have hesitation from the start sometimes.
Bear in mind with this method you are only replacing about 30% of the ATF. Some people have done it a couple of times so they replace more if it. 3 times gets you to about 75% In fact, even if the first service seems to help after a week, I'd probably repeat the steps 1-2 more times but only the fluid the additional times, not the filter and gasket.
Good luck.

I have the dipsticks,diy complete or partial fluid change is on www.benzworld.org w210 diy section. Work safe,work clean.Another good diy on www.peachparts.com resource section diy articles.
Have fun
I believe I had this done on the E320 at around 50K miles. You're a tad bit late for doing it at 85K miles. After I did this transmission fluid change at 50K miles, I had the transmission fluid changed on the other vehicles in the household around 30k miles.
-From the pan drain hole (this will only remove about 1/3 to 1/2 the oil, what's in the pan)
-From the torque converter drain hole (this is only available on 1999 and younger cars, not on newer cars, and it removes the remaining fluid not in the pan)
-By flushing (using a machine, hooked up to the transmission lines, to pump new fluid in and expel the old fluid).
Shops that only flush are bad. The flush stirs up the fluid and forces particles through the filter, clogging it. If you do a flush, make sure they also change the filter (which requires dropping the oil pan and manually draining most of the oil anyway), preferably changing the filter after they flush it.
On 2000+ cars, where you can't drain the torque converter, your best bet is to either machine flush and then change the filter (expensive, uses a lot of fluid, but gets it 100% clean), or drain the pan and change the filter, run the car a little, and then drain the fluid again (uses less fluid, but gets it only 75% clean). 75% plus a new filter is probably good enough to get back smooth shifts, however.

The total capacity is around 9.5 qts. A normal drain is 5 qts, so if you want to drain and refill twice you need 10 qts. A flush can take a lot more fluid because if you do it right you need to flush the whole system (9.5 qts), flush a little extra because the machine isn't perfect (1-3 qts), and then you need to drain and drop the pan to change the filter (5 qts). So, a proper flush should use 15 to 20 qts. Anything less and they're either not flushing it fully (defeats the purpose) or they aren't changing the filter after flushing (bad).
Your dealer probably has a flush machine, but you can always ask.
I will say that changing the tranny oil is only marginally harder than changing the engine oil. If you have the basic tools (ramps, hex wrench, torx bits) and basic mechanical sense, you can change it in 2 to 3 hours the first time. That will cost you $100, $150 possibly with new tools. Compare to probably $300 to $400 at the dealer. If I had to change it a second time, I think I could do it in 20 minutes. It's that easy, once you realize it. You just get intimidated the first time because it's a transmission... oooooooh [ghost noises in the background]. But seriously, not bad at all.

, but that doesnt work wit cars, especialy i got this phobia for taking apart the germans.... i do have the tools (unless there is some specialty ones). Also im guessing u needs somekind of pump to get that new fluid in there right? and ofcourse the dipstick thats sold separately....i have purchased already a tranny filter with the gaskets... now im just deciding on wat should i do... whether i should atempt this myself or just let someone who does this often do it.
So wat ur saying is that once i drop the pan ill get about ~5 Q out (50%), so 2 flushes (total 10Q new oil) should be good enough?
