Thank you for bringing Step 4 to my attention, I had neglected to update that step to reflect the ZF information. You should NEVER release your foot off the brake.

Yep nothing fancy. There's no drain plug IIRC so you need to figure out how to suck out the fluid. I used thin poly tubing to mine out.

I deeply respect the attention to detail in making this for all of us to use! I want to do this myself, I have the tools for it, I know my 5er will greatly benefit from a drain and fill.

One big reason I don't do this is the need to keep the car level. I'm also not young enough anymore to do all this work lying on my back.

Good write up. Bout to do this after I swap coil packs, spark plugs, water pump, and front brakes. Sitting at 53k miles.

This is a great write up .. I actually only saw this AFTER I did mine ... a couple of small details I did that perhaps might help others.
1. When draining the transmission fluid, I jacked up the front of the car as high as I could since the drain plug is towards the rear of the pan. You get more out that way and there actually is more space under the car with the front end tilted up 2. When I removed the pan bolts, I loosed all of them but did not remove all of them completely. Kept 1 or 2 in the front and 1 in the back and tilted the pan around to drain as much of the remaining fluid through the drain hole. That left very little in the pan. I saw Youtube videos of people making a big mess .. I managed to do this with minimal mess. 3. When filling I removed the front left jack stand and left the right front one in place and jacked up the right rear as high as it would go. I managed to fill about 3.75 liters with the car in this position and put the old drain plug back in temporarily. 4. Then I had to start the car and run through all the gears (not moving the car of course) then managed to fill to 4.75 liters total. I have done this before a few years ago on another 535i but forgot some of the steps so did some refreshers on YouTube. Wish I had used the pressure filler approach. Using the hand pump really sucked cos the tube that sucks up the fluid kept dropping off and the plunger kept sticking too. I actually made a similar pressure filler for brake fluid .. don't know why I didn't think of it for this. Next time ... |

If you go hand pump method or syringe method, it realistically becomes a 2 man job unless you're a masochist (and it's far easier just to pay someone to whip you instead). The ONLY downside to the pressure filler is that if you fill it with more fluid than you need, that fluid is "wasted". That said, you shouldn't be mixing the trans fluid with other fluids, and so just capping off the pressure filler and leaving it for the next service is what I did (had about half a bottle left in the filler). I made mine for like 20 bucks IIRC so it's not like I'm "wasting" an expensive filler.

It is a good rule of thumb during any project.
If you remove the drain and all the fluid and then find the fill bolt is seized, stripped or you are otherwise not able to remove it, then you are stuck. Always loosen the fill bolt first… applies to any fluid system. Last edited by LivNowPayL8r; 10-07-2024 at 09:06 PM.. |
