E un manson de plastic cand dai baia jos il vezi practic prin el trec ceva fire http://www.ecstuning.com/ES241980/ http://www.xoutpost.com/bmw-sav-forums/x5-e53-forum/86953-transmission-leak.html It is important to change this sleeve while you are doing the trans fluid because they are prone to leaking and if fluid gets to the connections that the sleeve is supposed to protect it can short out your mechatronic unit which is EXPENSIVE. Your mechatronic unit is the same thing as a valve body it controls the shifting for your transmission. Mechatronic connected to mechatronic body, and all wiring that coming inside transmission going thru this small place. Oricum daca nu ai schimbat acum , asta e , nu te stresa . Unii spun ca se poate schimba si fara sa dai jos mechatronicul , altii nu , nu stiu exact cum e , daca se da jos mechatronic probabil mai creste si ceva la manopera si daca tot ajungi acolo mai e un rahatel de plastic care vrea schimbare , vezi in schema de pe forumul ala part 2
