BTw, the easiest for DIY, would be to get a rebuild complete trans (with up to 1-yr waranty) then send yours in as a core.
I have consulted with BMW dealership. They suggest complete transmission replacement, but they know the problem is not with transmission, but rather with torque converter. Reason they are suggesting transmission is to eliminate any possibility of future problems and not to be responsible for future repairs. I want to understand, if I proceed with torque converter replacement and not transmission replacement, will I still have to deal with transmission in a month or will this fix the problem and give me at least 50-100k miles of no problems?
