Trans Fluid Fill Procedure Question (Not the Usual Ones)
Why ask this you wonder? Because of the aforementioned packaging the fluid fill will be infinitely easier with the other stuff out of the way. The fill plug is on the back of the trans FACING the xfer case! WHY?! Why you do this BMW? With the Xfer case bushing out and the trans supported on a stand I have a straight shot to the fill plug. Thank you to the collective for any infos.

There should be no problem going thru gears with driveshafts disconnected.
Isn't the oil fill plug there on the side? |

There is indeed a plug at that location. But the TIS points to a different 8mm hex fill plug at the back of the trans for fluid fills. Here is the TIS link: TIS trans fluid fill
Now that said. From what I can find EVERYONE, and I mean everyone, uses that fill plug you pointed out. I guess I'll go ahead and do that as well since it is A LOT easier to get to. Plus, then I can rehang the exhaust and I don't have to find out what an open header N52 sounds like.

I suspect you will get a code if you run through the gears with driveshaft disconnected. If you want to hear open exhaust I would do so in Park. Then put if back together and use the fill hole as posted. Do you know the trans filling procedure?

I am familiar with the fill procedure, yes. I have about 3.5 liters in it currently and wanted to ask the question before proceeding. In my head everything should be fine running the engine and trans without front/rear driveshafts connected but wanted to confirm. Maybe I will start the car up without the exhaust just to see what the open headers sound like.

You can run the xdrive with the FRONT driveshaft off but likely NOT the back. You will have no way to stop the spinning of the output shaft. I suppose you can maybe go into neutral. I had a similar problem when I changed the transfer case and wanted to do some testing part way through assembly.
TC doesn't need the precision of transmission I actually filled that before installing into the car. I remember at one point realizing it would be a problem trying to go from R to P if I can't hit the brakes. You could possibly go to N and very quickly to P or just turn off the engine when done working through the gears.

I hadn't thought of stopping the drivetrain. Duh. Thanks Andrew. Not sure how long it would take for it to stop by shutting the engine down. But I'd much rather hit the brakes. Fluid fill in xfer case has been completed and bushing replaced (you'd be proud of the "tool" I created to do the job) so I'll replace the flex disk, install heat shields, and the exhaust before continuing the fluid fill. Thanks again.

This might be the only time I'm glad my ZF trans is bottom fill...

Okay, got everything together. Threw a total of 7 liters into it and just barely got a trickle coming out of the fill port @ 113F. Hopefully that's okay... because that's all the fluid they sent me for the trans service kit. I would have much preferred to see a nice stream coming out of it. I do have some pentosin spec'd for the 6hp26 but I'd rather not mix fluids in the gearbox. Thoughts??? Do I leave it on the stands and order another liter of the Liqui Moly or think it will be fine?
