My tranny is toast. What are my options?
You have three real options: 1) Send the existing one out for rebuild. I fix these at my shop in Virginia (use the “Contact Anton” link at the bottom of the page). Seems to typically run $1000-$1300 depending on what needs to be done. Some dealers will rebuild them, some won’t. Many would rather sell you a factory refurb. 2) Factory refurb, over $3000 last time I looked, if available. Unfortunately, quality is an unknown and it’s quite expensive. New transmissions are no longer available from BMW. M93 trannies are not available even as refurbs; replacement is not an option. M93 owners can use a later transmission but the gearing will be lower unless the final drive is changed also. 3) Buy a used tranny for $500 or so. Cheapest, but you may be buying an imminent problem. Not worth doing unless it’s an M97 or rebuilt to updated specs.
