hi everyone it has been some time since i posted. just an update from my previous threads about the famous or infamous tranny bucking upon the 2nd to 1st downshift...about 3 weeks ago brought the x in for contiuation of the same problem and bmw reprogrammed the tranny once again. this time they could not clear a fault code and had to be guided by bmw tech center to clear the code. got the car back and although it was better it still had the problem when coming to a slow gradual stop when the tranny shifted from 2nd to 1st as usual. brought the car back last week and i requested the service manager and explained to him that this cannot continue aand that this is going to be the fouth time for the same problem and obviously reprogramming is not working and at this point i am requesting a new tranny. i told him that i had been in contact with bmw na and the authorization to replace the tranny must come from the field rep. he told me that their is only one rep for long island and he doughts that he would be interested in a 2005. i told him that the vehicle is still under cpo and bmw has a responsibilty to correct the problem. he told me that they would check the car over and if the problem existed he would be my advocate to try and get a new tranny authorized. i apologized for being a little angry but that he should understand my frustration. we left on good terms and i would be advised of the outcome. on tuesday i was called by my service advisor and informed that bmw had authorized the tranny exchange and it was coming from germany. the sa called yesterday informing me that the x is ready. will go get her today and hopefully they did a good job and problem resolved. the work was done at bayside bmw which is where i purchased the x. 2005 4.4 with 29500 miles. lets hope for the best. sorry for long post rob.
