I'm looking at a 1998 BMW 323i cab in great shape with an auto trans for nice days, but the seller says it needs a new trans. The car is about $1500 obo. From what I've read, there are two auto trans for this year.

Are they interchangeable? Are other BMW trans/years interchangeable?

Is it hard to rebuild one? My local shop want $2800-$3200 to R&R the trans with rebuilt. Lots of money there. They are getting back to me about just a rebuild and I R&R it.

What about used? What are my chances of getting a used one?

Thanks.
