I am so sorry about your truck. I have a 2004 RR HSE and had to replace my transmission two years ago at 140k miles. The dealer quoted 12+K for a new transmission + labor and told me my car was totaled. I contacted an independent just outside of Chicago and they put in a rebuilt transmission with a 1 year warranty, installed for 5.5k. I have the BMW 5 speed automatic transmission. You may have an 8 speed transmission. Please let me know if you would like the name of the shop I used;they are very reasonable with pricing. Good luck!
