You just need a 14mm hex head socket and 2 quarts of some 75w90.

A few images of the trans, xfer case, and diffs. I figure these will help me locate the plugs. (#5 on the trans, #10 on the xfer case, #10 on front diff, #5 on rear diff).

I picked up all the crush washers from Pelican parts.
Got the fluids from Turner:

Seems like getting access to some of these plugs is going to be pain in the ass.

No it's easy with the car on 4 jackstands. Just take the front two shields off. The front fill faces the driver's side wheel. The drain points down and to the back of the car.

Put the 14mm socket on a 3 inch extension- can easily get all 4 this way.

i just did this fluid change with royal purple. Another DIY from mad russian.net says to use 2 bottles and also get a third. I probably used only 1 1/2 bottles. Do m3's use more fluid then a regular m54 engine?

I am not sure about M3's but I just flushed my 323ci's tranny with a little under 2 quarts of Redline MTL and about 1 1/2 quarts of Redline 75w90 in the differential. Car shifts like butter now - would highly recommend this to anyone with a manual

Thanks for the sweet write up, each step worked flawlessly, the zip ties are needed for tubing if your not using a pump, without them oil will get everywhere lol, and boy is that stuff stinky. I noticed alot smoother shifting and gear engagement with the Royal Purple.

im having issues with my 2nd gear popping out of place and reverse no longer activating the mirrors. should i try flushing the trans. fluid or should i just go ahead and accept its the trans mounts or possibly the bushings/synchro's that need replacing. (which means i have to fork over $$$ to rebuild the transmissions forks/bushings.) pun intended i just bought this car and its already as bad as my audi s4.

I know its been a while but for those who stumble on this thread - for mirrors, toggle the left/right switch on the mirror adjustment knob to the driver side.

And CaptainMorganS4, any updates on your issue? Just wondering..

Question

I've seen other posts/videos and have heard from some of my mechanic friends that you should flush the transmission at least once before buttoning it back up...Maybe flushing isn't the right word...they say to drain the old stuff, fill it with new and run it though the gears, then to drain it again and fill it with brand new fluid...thoughts?

Nice write-up & pics! I'd add one other step to the procedure: drive the car at least around the block to warm up the fluid before you drain it, as it'll drain quicker and more completely. If you've been driving the car for an extended period, let it cool off for 30-45 minutes so it's still warm, but not scalding hot.

I changed my transmission fluid today, it was very easy to do. You do not really have to jack up all four wheels to get the car level. Instead I jacked up the front of the car drained and filled it then lowered the car back down to get it level and let the extra fluid drain out of the fill hole.
