350 SL, R230 - 300 SL, R129 - 1964 Corvette Sting Ray Sport Coupe - Porsche 911 Twin Turbo (sold)
My Indy told me when we were suspecting a rear engine seal to let him buy the seal from a Parts Store (think it was Advance or Auto Zone not sure which) because if the seal fails they will pay him for the labor to replace it. So with that assurance a Mercedes Part might be less than advantageous. I did buy a new plate which holds the seal and one-use bolts for the job that never happened.
I forgot to write that i had a scratch and rust free 1966 Mercedes S class (which i regret so much trading for a SL, R107) that i changed all oils on including the rear diff and the diff ended up with a leak after the oil change
Note that i did not do this job myself but a shop did it.. They might have used the wrong oil for what i know..
If your car is a 2004 SL, R230 you have the 5 G-Tronic automatic transmission
The amount of oil on the automatic transmission holds 9,1 US qt or 8,6 liters on the 5 G-Tronic automatic transmission (it says so in the owners manual on page 342)
I am sure you car will turn out great

I guess that after the oil change i did on the Mercedes several years ago have made me suspicious on non Mercedes oils and parts like seals and those kind of parts

Hi.
Glyn is a very knowledgeable chap, i enjoy his posts.
I wonder where ATF+4 fits into the list of fluids for the 722.6? It does not have any MB approvals, yet is the recommended fluid for Jeep products using the 722.6. These are German manufactured units too, not American ones.
Anyone know if ATF+4 is the same 'recipe' as the Mercedes fluid?
If anyone is looking for a fluid to use for their tranny service, then ATF+4 may be worth considering instead of a multi vehicle one, Particularly in America where it is cheap and plentiful.

The only fluid I would run in an early 722.9 is Pentosin ATF 134.

The fill procedure has a limited margin for error. You need the 722.9-specific adapter, a pressure-filler with a high capacity (was a PITA using my 3L one), and the temperature window to set the level is very narrow.
Here's a video (time-stamped) showing the correct way to set the level:

Hi.
Fair enough, i presumed that a well known brand such as 'Valvoline' would be expensive compared to an ATF4 from somewhere like 'Walmart'.
Still, ATF4 is still a fluid that has a manufacturer approval for the 722.6. Gives a little extra choice.

HLG, I wish I could hear from someone technically savvy what difference does it make and why having few CC more of ATF inside these transmissions!

There’s always oil and transmission fluid debates and fears for using the wrong kind. There really isn’t a definitive answer for your question, mostly speculation and concern for damaging an expensive part. Not sure why you would want more fluid in the trans?

CDK, not that I want more ATF fluid in the transmission, but wondering why the Germans want to be extremely precise on the amount of fluid that is contained into the pan (Perfect level and exactly 45 C )..!). Most vehicles with a dipstick have a high and low level and rarely they specify a measuring temperature on the fluid.
Engineering wise, everything that is measurable has a tolerance range, and that range is determined by a functionality. Now, going back to the ATF level on that pan, what would be the tolerance on the volume and what is too much or too less, and then why! So far that is a mystery to me since the total volume of ATF in that transmission is around 6 L ..!
