I have a 2013 SL550 and just received the "AT Service" message on my dash. I'm curious if anyone has done this service themselves rather than taking it to a mechanic. I looked around youtube to see how it's done, and the difficult parts seems to be getting the new transmission fluid into the pan, since it has to go back through the drain plug hole, and ensuring that you put in the correct amount since theres no dipstick.

So I'd like to know a couple of things: 1) are there any hidden issues with me trying to do this myself? (should I really just have a mechanic do this?) and 2) for those that have done this themselves, can you give me some guidance on how to do this?

Thanks.

You really will have a difficult time doing it. I own a shop. You will need the pump to put the fluid in and the adapter. Taking down the pan and filter is straightforward. You can buy what you need from AST. to put the fluid in. Then you will need to run it with the drain out to get the correct level once up to temperature.
not for the first timer

It's worth the cost to have a reputable shop do it. That's what I did at the 7 year mark but only 30k miles.

Get the kit from FCP Euro and pay the dealer the labor to do it. Figure about 2 hours labor. There are plenty of youtube vids on how to do it. FCP Euro has a good one. If you have a lift, then it will be much easier. But since you are asking how to do it, take it to a mechanic that has the skills, knowledge, tools, and ability to do it. As @rmorin49 said, you only do this every 7 years (or 60,000 miles). Should be about $700 to have the dealer do the whole thing with their parts.
