Since the fluid in tc is very little to begin with, make sure, as best possible, that the car is level. Another quick point, For me, racheting 14mm wrench worked best/easiest (anything to make life easy while under there...) Cheers. |

Ditto the amount of fluid in the tc...cannot believe the dealer says not to change it.
Thanks for the tip, I have yet to crawl under the car. What model of BT tool do you have? I'd like to get one tool that works on the BMW and the Volvos I have, too. |

Thanks jacobsed. From one of the posts on this forum, I was led to believe there may be a difference in the 2007 model year. That, and the dealer trying to dissuade me from changing fluids.
I'm attempting it, anyway. Bill |

Definitely do it. The hardest part was handing over the money they charge for one liter of the TC fluid. You have to buy the BMW fluid, there isn't an aftermarket substitute. I put redline in my diffs and manual tranny. Last edited by jacobsed; 01-15-2013 at 07:26 PM.. |

Just need to do it...got four new jackstands that I needed anyway. I went with Bavauto's LiquiMoly diff oil, did the rear already. I bought the BMW TC oil, almost $60/L. I got a case of Valvoline Dexron VI for the GM tranny. And pumps, etc to fill it. The car has so little clearance, it will be an effort getting it up on stands.

Changed the TC on my build date 1/2008 about 30K miles ago, I believe I used ATF and all is well. Probably rechange this summer. Car has 120K miles on it now.

Well, I went to great lengths to get the 'correct' BMW TC fluid, even the recommended diff fluid (even though RL would work). The latest dealer I spoke to did nto comment when I told him I was putting Dexron 6 in the tranny.
I hope I don't spill 500ml or so just getting the BMW stuff into the TC! |

Good idea. All I could envision was the 1L bottle tipping over in the middle of the process...I even thought about duct taping the bottle to the concrete floor.
I plan to use my new Northern Tool transfer pump on this, before it gets contaminated by ATF. I'll try your idea. |

I used a cheap bottle pump like this.
http://www.walmart.com/ip/Torani-Syr...00000007346530 I clipped the very end of the nozzle off and pushed a piece of hose on the end of it. Now its my TC fluid only pump. |

I did however use RL in the diffs and manual tranny. RL is an equal or better substitute. The GM auto tranny takes Dexron VI according to Bentley manual. Shell M-1375.4 is used in the auto ZF tranny. Last edited by jacobsed; 01-19-2013 at 06:49 PM.. |

Update: Yesterday I began the chore, got the front diff fluid changed, and the stuff that came out was not that bad. I was not successful in removing the TC crossmember, so that will wait for another day.
I've re-thought the tranny fluid change, and think I will do a gradual drain & fill. I'll drain the pan, and add 2-3 quarts at a time. The filter can probably wait. I wish everything was as accessible as the front diff. |
