Thanks for that info and insight on the TCM. Can we force a tranny learn with HPTuners? Or, is a Tech2 or similar (dealership only) type device needed?

It appears the TCM is external on the 8 speeds based on post 5 and 8 here:

Bumping this to the top - hoping someone can shed some light on the different AC algorithms. Thanks

Looking at some stock tunes from the repository, it looks like they switched to a "P59" PCM in 2004. Any info on significant differences between the P01 and P59?

Thanks for the clarification. I thought that the 0411 was replaced in 2004? Any advantage to the 2004 PCM?

Thanks.

What is "P01"?

Any reason a 2004 is better that a 2003, 2002, or 2001? I'm looking to buy the PCM once and not have to update OS and pay additional credits, if possible.

Thanks

I?m doing a LS1 swap with drive by wire. I need to buy a PCM and choose an operating system.
