E36 a4s-270r to a4s-310r swap trans error light. Trans seems to work right but haven't confirmed due to a wheel bearing issue.

The original trans was 960.18032 RX from 06/96 328i the replacement is 960.17180 MW.
Virtually no information on this issue and I have spent a lot of time trying to figure it out.

The 2 most definitive answers are #1. yes they will swap no issue and #2. no they are not compatible with a variable of #3. reprogramming or flashing the TCU.

Looking through realoem I can't find the specific MW trans so no clue what it is actually from. Closest idea from ebay is 94-95 325 but not according to realoem.

I tried disconnecting the battery with no difference in the dash light.

Anyone have an idea what should be the next step?
