BMW Repair Questions? Ask a Mechanic for Answers ASAP
sorry to hear of the problems you are having
it is not common for a BMW transmission to fail at this mileage, especially if it has never had to be serviced or had any problems in the past. BMW transmissions can fail at relatively low mileages (between 100 and 150k miles) but 50k is VERY low for this so there may have been some defect in this particular transmission - or it could just be random bad luck.
If the fluid is burnt and contains filings, then I am afraid their diagnosis does sound correct - this usually points to the need to replace or rebuild the transmission.
If you are out of warranty, then unfortunately BMW has no responsibility. However, you can ask BMW corporate and your dealership for goodwill assistance in covering all or part of the repair.
