Hey guys im new here and wondered if anyone has done a service (flush and fill) on their transmissions that bmw says never has to be done. I know it takes a special fluid and the filter is built in the pan. the questions i have is where to purchase the pan and fluid and how to actually drain and flush? threw trans cooler lines via flush machine or??? thanks, Ray

All BMW transmission services are fairly similar. We did a video for the E39, you could easily use it as a guide to how to service your E90, you can find that video HERE. As for where to get the fluid and other needed parts, I have service kits available HERE for your 325i.
