GLE43 Transmission Filter and Fluid Change Procedure (725.0)
Hi everyone,
I'm getting ready to do a transmission filter and fluid change on my 2017 GLE43. I see varying opinions on draining the torque converter. I also see conflicting reports on how much fluid it should take. I ordered a kit from FCP Euro which includes the filter, fluid (10L) and bolts. I also ordered the special tool kit to drain and refill (I already have a Mityvac Fluid pump). Any words of wisdom from the group before I take on this task? I'm at 100K miles (dealer did the first change), and I hope to go for another 50k or so before I get a new one, so I'd like to take good care of it. Thanks in advance for your help!

You need new pan bolts they cannot be reused. For the 9 speed 725.038 total fill is 10.6 quarts.
Also you need to know if you have code A89 (Reduced-Friction) or not because there are different part numbers not sure if this applys to the 9 speed trans. I would look into it just to be safe when ordering parts different filters and trans fluid..
Some information to look at

I did this on my GLE400. Since yours is a 4matic, you will need to remove the two braces on each side of the transmission then drop the transmission. Use a hydraulic jack to hold the transmission up while you drain and refill.

Dropping the transmission is not part of the WIS instructions.
WIS instructions are likely on this site somewhere.
Drain the torque converter if it has a drain plug. Not all torque converters have drain plugs. The only way to know if yours has a drain plug is to visually inspect it.
Watch lots of YouTube videos on this, there are some out there. Senior Leigh on YouTube has good videos on the 722.9 for W212 E350. The 9G will be generally similar.
Excellent video here:

Thanks guys!
Also yes, mine is the 9g so I think it will be a bit easier of a job. Going to check out the video shortly. Luckily, this is preventative maintenance and I have the parts already so no big rush!

So I do have the 9G but due to that its 4Matic, you have to remove the braces on each side and the transmission brace in order to be able to remove the pan. So when removing all three braces, the transmission will drop and that is why you will have to use a hydraulic jack to support it. Its pretty simple. Just time consuming. The video there shows the GLC300 rwd and not 4matic. Setup underneath the GLE with 4matic is a little different.

That's odd There was no braces on the 7G to remove. Do anyone has a photo of the (3) braces on the 9G. I love to see on how the pan is removed.

After watching a 9G trans service on a W222. You do have to remove one support brace because the trans pan sets above it. and the Trans mount brace and that's where you need to support the transmission to drop the pan due to one trans pan bolt. I'm thinking it's almost the same way as in the 9G GLE/GLS.

W166 with 725 transmission, but OM642 diesel.
GLS450 with M276 3.0TT and 725, shows some transmission work.

Any update on the Trans Fluid Change on the GLE43? Was it difficult to remove the trans pan? Was there a torque converter drain plug? How many quarts of fluid.
About to tackle this on my 2017 GLE 43 and need any advice or encouragement you have.
Thanks!
