So, GMPartsDirect is telling me that the part no. for the '04 PCM is 12586243 and for '05 it's 12602801. If that's correct, I bought an '04 PCM for my '05. :rant2:

Can anyone confirm this? :confused:

Either part number will work with a LS6. The 12586243 is what I've used on both year Vs. You know my theory on your PCM - the fuel injector drivers are bad.
