ATF check

I thought working on these cars aren’t that complicated but after researching on how to check your transmission fluid takes an act of a small miracle as it seems. Pulling out and hooking up your STAR or aiming an infrared laser blaster to check trans temp to be at exactly 80c in order to get an accurate dipstick tool reading is no easy task man! Luckily you only have to do this procedure once in awhile.

Thanks for the DIY - just did this today and it was pretty easy. I started with about 3.5L but after my 20min drive was still a decent amount below the 80C minimum line. Ended up adding the entire 4th bottle so about 4.25 quarts and I’m now right at the max line. I’d prefer to have it somewhere in between but should be fine. So a word to the wise - top off slowly as it doesn’t take much to bring the level up.

Hey guys,

I am having some issues when trying to change the transmission fluid.

When emptying the fluid, I could not accurately measure the oil that came out due to the fact that the drain plug was stripped. I did however add 3.5 qts and it turned out not enough. I could feel it was not engaging Reverse and drive easily. I came back and measured and the level was definitely low. I then added a qt, and that definitely made the shifts smoother however I am now not getting a reading in the dipstick tool.

Any ideas?

It will take 4.75 if you drop the pan and filter.

Great info, just in the process of doing my transmission. I noticed the brown fluid that came out compared to the red fluid that I got from the dealer. OP mentioned the same thing, but I’ve never seen fluid go from this red to the brown that it is. Is this correct? I know BMW uses a brownish ATF fluid on some of their cars, and there is zero hint of red in the old trans fluid so I’m afraid of mixing two different oils. Is this an issue? Does Mercedes use some brown trans oils or only the red? Thanks for your help.
