No Transmission Flush at Dealer?
Took the beast to the dealer this morning for some minor problems and a transmission service which I always thought included the full flush. Was told MB no longer does that and only drop the pan, change the filter and top off fluids now.
Since our cars hold a lot more then the three or four quarts in the pan it seems that just adding new fluid to an equal amount of old fluid remaining in the converter etc. wouldn't accomplish much.
So, what do you think about a transmission service that doesn't exchange ALL the fluid and mixes new with old?
Worth doing?

I did it 2 years ago to change the tranny oil cost $250 in Anaheim Mercedes.
I dont even know if the change the filter ... they should be able to change the oil without problem.

If you’re soon sending it down the river, premature failure from lack of maintenance will be a subsequent owner’s costly problem.
As you’ve noted, a dealership work order specifying traditional “transmission service” consists of dropping the pan, installing a fresh filter, and then replenishing the ~4 liters drained. To my mind, that’s akin to drawing a ‘fresh bath’ for your lady after having drained the old water only halfway. It’s better than doing nothing, and affords an inspection for undue wear debris, although complete ATF replacement is clearly preferable. MB will do complete flush as a matter of course when glycol contamination is indicated, and has published a workshop procedure on how the relatively simple task is to be completed. RoW markets have long specified 39,000-mile 722.6 drain service intervals. IMO, Daimler erred when fitting a torque converter drain plug only to its 2000+ model year commercial (e.g., truck) five-speed variants. Not coincidentally, all 722.9 7-speed converters are so equipped.
BTW, total circuit capacity (valve body, torque converter, and the radiator’s integral cooler) is approximately 9.5 liters.
Budget ~$150 street price for the ATF, filter, and sundry consumables required for a complete DIY flush. I’d suggest using only approved 236.14-specification fluid.
Round up accordingly if you’re farming the job out.

My take on this is to do the following:
1. Flush the transmission.
2. Drop the pan to change the filter.
3. Top off the fluid.
If you do step 2 before 1, the old fluid could contaminate the new filter.

Thanks for the info, I have a hard time finding the Shell at the local auto parts store. It seem it as to be ordered online. With the tranny filter change how much do you ended up adding. thanks.

SOLD 04 E55 Now 93 w124 3.2 sold W210 E55 sold waiting on W211 E63 p030
My car has been serviced its entire life by Mercedes, and they never touched the tranny fluid I was told by two different MB techs one being a Master Tech, that if the fluid was never changed before 80000 miles no need to flush or even touch it I was told I would be asking for trouble if I did

This can get complicated, some dealers were doing complete flushes, which was really supplied equipment and fluid by aftermarket companies, such as BG. Well, MB does not approve any aftermarket trans fluid. So, If problems occur under warranty and a aftermarket flush was done, guess what? This is why now the dealers are only doing "MB approved" transmission services to avoid that bind. Now, it is possible to use the same equipment, but with MB fluid. Also keep in mind, when doing complete flushes normally they do not change the filter. I also do believe 722.6 rrans do (some) also have tq convertor drains. Not all .9s do.

My dealer offers two different transmission services.
1. Tranny flush - pump out the old fluids by back flushing the system, doesn't make any sense to me, as you can't flush a filter clean.
2. Transmission Service - drop the the pan, drian the old fluid, replace filter, pump in new fluids.
I had my trans service performed at a indy shop, much cheaper then Mercedes at $130, using Mercedes own fluids.
Now that car feels stronger and harder on pulls.

The transmission used on the w210 and w202 were fairly problematic to begin with, they failed even with out a transmission flush. Our transmissions are much stronger than those from the older body styles. I know that they are the same transmissions, but they did various upgrades or changes.

I did a complete transmission service (flushed out all old fluid, changed gasket and filter) myself. I used Genuine MB fluid. Used about 9 liters of fluid. I did it myself at 40k. Have 60k on it now and will do it again at 80k. There is a great DIY for this!

Won't help you because the E55 and E63 have different transmissions.
For instance, the 722.6 has a opening to fill from the top. The 722.9 must be filled through the drain plug. Research the links, I have posted them at least 3 times.
