Default Computer Relearn Failure

2001 Saturn SW2

I have been trying to install a new PCM.

I am using the orignial Body Control Module. Since my car is a wagon and they are very rare up here.

I just did a Transmission swap from an Automatic to Manual transmission.

The car also has an Instrument Cluster out of a 2006 Pontiac Torrent.

I have tried the PassLock re-learn procedure over a dozen times in various ways, but I cant get the new PCM to work.

four possibilities are
1. I don't have the right PCM
2. I really need to have it professionally done.
3. I need both an ECM and PCM from a manual transmissioned 2001 SW2
4. I am not doing the PCM relearn procedure right.
5. these new guages are messing things up

...
I drive a station wagon because I don't want to be cool.

REWARD EXCELLENCE!

There is no ECM. But AFAIK, "introducing" the PCM to the BCM goes beyond just the Passlock reset/relearn. I think I recall reading here that the right buttons pressed on a Tech II scanner will get them in sync. Problem is, searching for such info here on SF is gonna be frustrating, because the search ignores short (3 or fewer characters) strings like "PCM" and "BCM". Maybe your favorite flavor of regular Internet search, via Advanced Search and narrowing to saturnfans.com, will find something for you.

REWARD EXCELLENCE!
