I did the tranny fluid change today, and at 50k miles the old fluid was pretty dark. Lifetime fluid my ass, BMW! Now the 1-2 shift seems to feel smoother (I used to have to double-clutch when cold to ensure smooth shifts) so I'm very glad I did it.

While I was under there I manually powered the pump to drain the fluid in the cooler. As another poster mentioned, I did so by slitting open the pump wire loom and scraping off the insulation on the red wire (+12V). Then I temporarily connect a battery +12V to the red wire, and connect another wire between the battery ground and the tranny case (which acts as a ground for the tranny fluid pump). I manually connect the ground wire in 15 second bursts to power the pump 3~4 times. Quite a bit more fluid were pumped out of the cooler that way...until there was just nothing more to come out of the drain hole.

As for filling the tranny, I initially filled up to the fill hole level, then I hand-tightened the old fill plug and cycled the pump for another 45~60 seconds (also in 15 second bursts). Then I think I added another ~300ml of fluid and re-installed a new fill plug that I bought (I discarded the old drain and fill plugs).

Of course, after I was all done I wrapped some high-temperature electrical tape over the pump wire that I had exposed and doubled the protection with additional wire loom just to be safe. Overall a very simple procedure--figuring out how to power the pump and cleaning up the occasional spills probably took more time than the actual procedure.

By the way, my filter mesh screen was also very clean, but since I had it out I just installed a new one that I bought along with the new crush washer.

hmmn weird when i replaced mine at 50 or 70k i could still see some of the aluminum part and i wipe it down with a cleaner and parts were still pretty shiny.. maybe the dealer replaced mine at 30k. not sure..

yea brakes are really easy. if you dont have power tools make sure you have extensions tubes those nuts are hard to get..

Goto your local Home Depot or OSH, grab the gray colored Spray Master bottle. (This is the best one I found so far). Unscrew the spray tip, walk over to the clear tubing isle and match the smallest clear tubing that fit. There is only one size that will fit with a leak tight seal. It will be a bit tight but it will fit. Buy a roll of that tubing.

Once you get home, open the bottle, take off the strainer inside, fill it up with oil, cut a piece of tubing to length and screw it onto the spray bottle tip. You will now have your oil pump as the OP.

Hopefully, that's detail enough. I have one of these pump for every different oil for the different cars in the family that requires pumping. Can't thank the OP enough for showing this. Very clean oil change now compare to the stupid %#&)#!*&$ pumps I used before from auto stores.

Activating the pump w ISTA/D

For those who have ISTA/D, you can activate the pump under Activities, Engine, Manual Transmission. I used the Rheingold release:

Hey guys,

Any tips for removing the fill/drain plugs without stripping them? I came close to stripping the fill plug on my e90 330 when trying to do this. Then again, I tried it at 110k miles (I bought the car second hand) and it was probably never touched since production.

I'd hit it with some PB Blaster before, let it soak in for a bit, and then try. Make sure you have the proper wrench to apply a lot of torque instantly.

I just did this service on my 08 M3. My car only has 42k on it and I paid the dealer to do it once before. At any rate, the reason for my post is I used my brand new Motive fluid pump when I did it. It's basically a glorified garden pressure sprayer. If you are crafty you could make your own for less. But I have rigged up so many pumps over the last 20 years and tried all kinds of cheap POS pumps, I wanted to try a nice one for once. This is it. It is a pleasure to use. I pressurized it with my compressor and it filled the transmission fluid in about 1 minute on a single charge. Love the tool. I will use it on the M coupes next and on our GMC truck too.

Interesting the BMW manuals use ATF fluid. I assume the syncros must be similar to clutch packs etc.

Great DIY!

I've always tried to snake a tube from the engine compartment down and with a friend and a funnel just filled it. Haven't tried on M3 before. Could be way too tight.

It's much easier to reach from the bottom. I just hate those gear oil pumps you buy at the auto store.

You can also try the hand pump, fits on the redline bottles: http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1

Confirmed to fit the Redline bottles? I tried the store ones and they are too big to fit into the neck of the the Redline bottles. I ended up cutting the tops off the bottle to use the pump...

Has anyone experienced trouble with leaks when using the stock plugs on the fill or drain holes?

I changed my tranny fluid about 300 miles ago, and did a follow up check today. Used new plugs when fluid was changed. Found that I was down about 250 mL. noticed a fair about of 'crud' on the top of tranny cover. Tranny oil definitely coming out of the fill plug.

I replaced the drain plug with a Dimple magnetic plug. No leaks from the drain hole.

At this point I am assessing that the rubber seal on the fill plugs are mediocre. The Dimple plug uses a crush washer.

I torqued the fill plug to 25 ft/lbs.

Any one have any thoughts?

I will check again in another 300 miles and if the leak continues, I am going to go with an aftermarket plug.

I think you answered your own question. You replaced the OEM drain plug o-ring seal with a crush washer instead. Perhaps the o-ring seal is designed to seal up to a higher internal transmission oil pressure before seeping oil out.
