Yes not only is it possible, but quite a lot of MB owners do it themselves, and there are plenty of "How To" posts here on the forum. . Having said that, you will need at least rudimentary mechanical skills... like everything else, there are tips and tricks on what to do...If you have any doubts about your ability, get a professional to do it for you. Its for sure not as simple as changing the engine oil and filter. Each of the two main MB transmissions, 722.6 and the 722.9 have diffdrent change methods. Check You Tube " MB Automatic Transmission Fluid Change" and you will see plenty of vids on how to do it. Do your research well before youn start.
He probably has the fill from below 7g box , you have the 5g with a dipstick tube (I would guess )
This was my first attempt on the 7g change
Try telling Roy hull that
How many gears are in it? I'd say its the 722.9 trans, But to be absolutely sure, open the driver side front door, and on the piller, under the lock catch, there is a sticker. Under the DAIMLER AG, you will see a series of letters and Nrs, starting with WDD. This is that particular cars VIN ( Vehicle Identity Number) To deciper this, Google ( where would we be without it?? ) MB VIN Decoder, and select one from the list. Download the decoder, enter your VIN in it, and hey presto...everything you want to know about that particular build MB will be shown, inc engine and transmission type and code. Do that, and then we will know " Above and Beyond a reasonable doubt" what is in your Merc. You will find this data very usefull in future too, if youn ever need part's etc.
Yes, mine has the stop start so 7g+ I assume. To drain the TC in the stop start trans, you have to remove the auxilary pump from the transmission ( this is an electric pump which keeps the fluid in circulation while the engine is stopped during stop start operation ) Then you have to manually turn the engine until the drain plug on the TC becomes visible, and it can ge drained. The 722.6 does not have a drainplug on the TC, and so must be flushed out via the oil cooler pipes. I think that the 7G trans may have this feature too ( IE TC Drain plug) but I'm not 100% sure about it.
Compared to changing the oil in a manual transmission , yes it is but the autotrans is unbelievably more complex than the manual one, and has a hell of a lot more moving parts and electronics, The VIN decoder will give you a whole lot of usefull info about your car. Ive downloaded it on to my phone, and it comes in very handy when I'm in the garage ordering part etc.
