OK everyone I'm at the crossroads here.I have a dilemma my 2013 x1 35i xdrive m sport 215000 miles. Transmission is howling grinding 123 gears quiets down in 456gears. The dilemma put 3k in parts into it myself or junk it for something new. Has anyone replaced trans how difficult and what needs to be done coding wise ?
