The PCM I have in my car is from an L67 and I sent my old L36 PCM to the guy I got it from (we were having to play musical PCMs). He loaded his L67 bin back on my old PCM and his BBV works correctly.

I would say it's year dependent, but it can be and has been done. At some point the part numbers became the same.
