Do a search. I must have posted the docs 15 times in various threads. Get off your ass and do the work!

This is the 6 speed ZF tranny that goes into most or all auto E60s.

Amen Bro. Not to be rude, but don't be lazy if you want survive this board. Do the search. Search mechatronic and e60. You own a BMW and want to take care of it. You have to learn how to do that if you want to keep the car, or you have butt loads of money to throw at the dealer. Depending on the dealer, they'll be happy to make up reasons to take it.

Good Luck.

Update: Read this entire thread and you'll get an idea about what to look for and how to fix. Very good detail on last page 17. http://www.bimmerfest.com/forums/showthread.php?t=401524&page=17

Oceans10.. the newer Fxx 5xxs are using the new ZF 8 speed auto tranny. Think they worked the bugs out by now. Don't know why 6 speed was designed with the defect and what they did in mechatronic to fix it. Really not happy :mad: with ZF nor BMW on this issue. Mine isn't bad but will need replacing in another 25 to 50K. At least I hope I make it that long. :dunno:

It's a plastic sleeve that keeps various electronic connectors from being bathed in hot transmission fluid. Given constant exposure to high temperatures and pressure it decays and starts to crack and fray. Poor choice of material. Good news is the part is cheap, so if you are comfortable draining the fluid and dropping the pan it could be a cheap DIY job.
Not sure what the story is on the new 8 speeds in the F10 models.
