My car was in Thursday for the new transmission. Took it in at 8 AM, they called at 1:30 PM saying it was ready. I got a 325xi Touring (wagon) as a loaner - not bad, I wouldn't buy one, but it handled pretty much just like a 325i.
When I picked up my car, they had me sign a warranty work order. I noticed 2 things
1. The value of the transmission was $3650
2. It said REMAN TRANSMISSION as the description.
I asked the SA if that meant it was remanufactured (which I really new that it did). He said that he thought so, they had requested a new transmission, that was what they received from BMW NA. He invited me back into the service department to look at the old transmission and box.
They had packed the old transmission in the same box to return it to BMW NA. The box was very clearly labeled as BMW with German language stickers all over it, shipping labels in German, etc. There was also an inventory sticker that said REMANUFACTURED, so there really is no question as to what they are installing.
I've decided that this is not a big deal to me, especially since the first replacement transmission I got was a NEW replacement and it was bad. I am trusting that BMW puts the same quality into their remanufactured transmissions as they do original ones. Also, I would rather have a factory controlled rebuild, as opposed to a dealer service bay clutch pack replacement that may not be as clean, etc. A good, brand new transmission would have been ideal, but legally they can replace it with a rebuilt transmission.
The full warranty still applies, and if there are any problems at all, I will not hesitate at this point to pursue Lemon Law action.
I'll post a report in a few weeks or so. The car is probably going see little or no driving due to the cold weather and predicted snowfall here, so it could even be 2 months until it gets a few hundred miles on it.
By the way, once again, I have to say that I got very good service from the dealer. They were fast, gave me a nice loaner car, etc. I truly believe the dealer has to do what BMW NA says or ships to them. They even washed the car and had it warmed up waiting for me to pick up.
