      Transmission swap

      I have an 07 10/06 build trans that is going out. I found a 2011 10/10 build auto trans with 18k miles. Will this transmission be plug and play and just require coding?

      I don't see any problem then. It's mechanically the exact same thing isn't it?

      I hope so I bought it for $1025 thinking great deal. Does the n55 and N54 engines use the same auto transmission?

      You got me. I don't know. Considering BMW's money saving measures I'd lean toward yes. Realoem.com should solve this quickly.
