I did the diff and trans this weekend. Diff was pretty un-eventful.
The transmission was interesting, i drained out 4.5 liter, I put back 5.5 and got the trans to 140F, but nothing drained out, I put on another liter got it up to 140F again and then about1/4 liter drained out. So pretty sure I put about 6 liters in. The old trans fluid was very dirty/black. The old gear oil from the diff was perfect,
golden and clean looking.
going to drive it tomorrow and see how it goes, but now wondering if the trans was a liter low.
Getting the trans to 140F took about 30 minutes.
Didn’t see any leaks or issues. So have to assume when it was done before they didn’t put enough in ( car has 34k and I bought it with about 33k.
if anyone needs any tips on the process is was fairly easy, a couple of hex sockets, a 13mm for the rear frame that blocks some of the drain plugs and I think a 8mm or 10mm for the under tray covers. Took about 5 hours in total and I used a hand pump the 1st time and a battery pump the 2nd time.
When I changed my trans fluid I used a test tube stopper with a hole in the middle for the fill seal.
yeah, I used the Mercedes adapter which is the same thing. My concern was more around why I got 1/4 in more than I took out , even letting it drain . I can only assume whoever changed the fluid before underfilled it.
Did you change the 75W90 fluid? The manual calls for 4L of it. I believe the recommended on is Shell Spirax S5 ATE.
sorry been offline for a few days. I did used Spirax, I bought it from a forum member who sold his car, I believe he found it on lubefinders like Katie did.
If you have any questions on the process let me know, it was pretty easy, but have a battery or pressurized transfer pump, its gets very old/tiring with a little one
Followed you over from another post. I'm actually not too far away from you(Clemson) so it's pretty nice to see others that are willing to work on the car! Also how hard would it be to go without a lift? My place is not exactly very well equipped.

If you can get the car a good 24" up should be ok, just not convenient, there is a subframe at the back that has to come off to get access to the plugs, and then getting the feed tube in you want a bit of room to work with. just make sure you have decent stand that have some height and a good jack.
Interesting. My local shop said they were unable to do this service and it had to be done at the dealership....
probably to use the DAS/XENTRY system to read the trans temp. I used the AMG gauges and an infrared thermometer, my MBII tool can't read trans temp. I've read a few people doing this method on all kinds of cars, I did it on my Nissan GTR (sold) too and had no issues 10k miles later. Honestly it wasn't very heard, just took my time, I got a battery-powered pump from harbor freight for $10 so I didn't have to hand pump for days.
Did you have to pay any import duties with it being oil? I cant find any local sources and wasnt sure how to order through Lube Finders. They have a message mentioning import duties but not sure what they would be.
This is probably one of the better and more recent "go-to" threads for DIYing the trans oil service.
I just completed mine yesterday. I found a potential issue with backyarding this DIY if you are using floor jacks to raise the back end of the car.
I spent a little extra time conducting a test in two raised positions and the test results show that an overfill condition exists if the chassis in not level.
Here is the test and the results and thought this would be a good addendum to this thread.
