2012 ML350
Need some help
Hi folks.
Car in question is my wife's 2012 ML350 with a 722.9 transmission. Yesterday I changed the oil, air filters, fuel filter, and transmission filter and fluid. Today she drove it about 15 miles and it was running great then suddenly it started shaking and losing power. We had it towed home and I had a little time to mess with it before dark.
No obvious leaks anywhere, so I took it for a drive. I got about a block and it did what she said it did. I stomped on it and it picked up very slowly and was shuddering like it was missing. It took about 10 seconds but it finally revved to about 4K on the tach but would not shift until I lifted up on the accelerator then it kinda bogged down. The engine is not revving fast like the trans is slipping, when you stomp on it, there is just no power, but it idles smooth and starts up normally.
The only anomally I had was yesterday when I drained the trans fluid out of it I got about 4.5 quarts out of it as measured by a measuring cup. So I refilled it with 5 liters of the proper blue transmission fluid. Now the transmission kit I got from ID parts came with two 5 liter jugs of fluid, but I only used one. 4.5 quarts = 4.25 liters so I put about 3/4 of a liter extra in it, and when I removed the fill adapter from the trans, fluid started coming out so I put my thumb over it to stop the flow until I could put the drain plug back in.
My questions....
First off, do you think I have a fuel problem or a transmission issue? Second what is the approximate amount of fluid needed for just a drain and fill on a 722.9 transmission? Third, I drained 4.25 liters out and refilled with 5 liters. Is it possible the transmission still under filled, or overfilled (I don't see how .75 liters would cause this issue). Lastly, the issue first started after 15 miles of highway driving so the trans fluid was hot. Now it will do it after sitting for 6 hours and the fluid is cold.
Suggestions on what to do next.......

Is this gas or diesel?

Second, check oil level and see if the filter housing are secured properly.
Third, regarding with the transmission, did you get it up to certain temperature (i think it 45) before you let it drip out? Did you watch the YouTube video how to do it?
Since you only drain 4.5L, i assumed you did not do the torque converter. I will check again and see if there is any leak. Did you torque the transmission bolt property? Is the seal sit it properly? You have done few maintenance items at once. You need to go over your work 1 by 1 in order to ensure no mistake has been made. If you did not have this kind of problem, and have after the service is done. Chances are you fuked up. But it ok, take your time and find out the issues.

Hello Chassis,
Vehicle is a 2012 ML-350 Bluetec (diesel) There are 60,000 miles on the vehicle and we have owned it for approximately 2 years. Can't remember the link for the transmission procedure I used as I read and viewed many, but it was basically drain all the fluid from the pan, clean the pan, replace the gasket, replace the trans filter, and refill the pan with the Rowe MB 236.51 spec blue fluid (same as I drained out). As I mentioned I measured out the fluid drained out and refilled with a little more than I drained out.
An update though. I started the vehicle and got a mild smell of diesel fuel from the engine bay. Then, while it was in park, I ran it up to 3000 RPM. It held steady at 3000 RPM for about 5 seconds then slowly started dropping in RPM even though the accelerator pedal was not released. Finally it dropped to about 1200 RPM, I released the accelerator and it shook and sputtered like it was going to stall, then smoothed out. I revved it again and it did the same thing. I'm suspecting a fuel starvation issue now. There are no check engine lights and it starts and idles fine, but if you rev it up, it will hold for a few seconds then slowly drop RPM's until it almost dies. Wonder if my fuel filter I put in (a Mann with the 5 pin connector on it) is bad. or I have a bad fuel line. Funny thing, I put cardboard under it and nothing seems to be leaking.

Ml350 bluetec
Did you remove the turbo outlet pipe to get to the fuel filter? If yes, you need to check to make sure all the gaskets, etc.. on the turbo outlet are all installed and sealed properly. Also check to make sure the seal on the turbo inlet in sealing properly as well, I had a similar issue when I replaced the fuel filter on my 2014 ML 350 bluetec, it would hesitate and jerk as I drove it. No CEL or anything. Ended up being the turbo outlet gasket not sealing properly.

Yes, I removed the turbo outlet pipe and double checked that all gaskets were in place and sealing well. It turns out that I have a fuel leak. After running it I had a fairly strong smell of diesel fuel, and eventually had some wet staining on the skid plates. I'm suspecting one of the hoses going to the filter, or possibly the filter itself, as that is the only part of the fuel system I messed with.
