722.6 after filter change fill capacity?
 

Anyone know the exact amount of fluid to put back into the 722.6 transmission (on a '00 c280 if it makes a difference) after a pan removal and filter change?

I'm thinking it would be more than a "drain and fill" since all of the trans services I've done on other cars, more fluid comes out when you remove the filter.

Anyway, if anyone knows from experience, I'd like to hear from you.

The URL at the bottom of my post is not a complete answer to your question, but I found it to be interesting.

I do not own an MB with a 722.6 transmission, but from what I've read here, you may get the usual "filled for life" BS. That's a story the dealer wants everyone to believe. It's basically a line of you-know-what designed to sell cars to the majority who prefer not to maintain their vehicles.

I wouldn't worry about the "quoted" capacity. Do this.

Drive the car for 15-20 miles to fully warm up the transmission. Afterwards, do the dipstick check and note the level. If it's full, skip to the next paragraph. If not top off in slight increments until it is.

Shutoff motor and drain pan and converter, although from what I've read, you may not have one. That shouldn't be hard to determine. In either case, drain and capture all fluid. Also catch what comes out when you pull the filter. There will be more.

Now measure it....all of it and pour that amount back in after you replace the filter and refit pan and all drain plugs.

That's all there is to any transmission fluid change with the exception of units w/o drainable converters. If that's your situation. drain what you can, change filter and move on. Automated flush systems have been known to deep-six transmissions as they break debris loose and a miniscule amount of debris will kill a transmission. This sort of thing is more likely to happen to someone who decides to flush a unit that's been neglected for years.

Needless to say, one must use the correct fluid for the unit being serviced.

Mike,

Thanks for the reply. My car does not have a converter drain plug, or even a dipstick for that matter. :( That is why I'm looking for the exact fluid refill spec after a filter change.

I've read here that MB dealers have a kit for some MBs not equipped with a dip stick. I cannot say if yours is one of these models.

The kit includes a dip stick that gets you back to where things used to be.

Perhaps someone who's been thru this will chime in with a part number.

If not, call your local MB dealer Monday and see if it's available. If they tap dance, call Phil at this sites parts forum.

I just did this on my 2000 C280, no torque converter drain plug, capacity about 7.5 liters, I think. New filter and gasket. I drained almost exactly 4 liters and I put back 4 liters plus 50ml for the filter. After driving for awhile to warm it up, the special Mercedes dip stick showed the level right on the mark.

Even though I drained by the plug and then removed the pan to let it drip some more, there was a good slug of oil behind the filter so be advised when you pull the filter off. Also when installing the new filter push by the neck of the filter and it will "pop" on and then the body of the filter will be flush to tranny body.

There is a lot of info on this topic on the net.

Here's one.

Glenmore, thanks so much for the info! It's nice to hear from someone having performed this on the same year and model as mine. :)
