No, you read it right. I won't argue that, I will let you know the bulletin was updated on April 7, 2011. #04-07-30-037E is the new number, compared quickly everything looks to be the exact same info.

Like I said, try it. Let me know how it works. I've seen 100,000 mile trannys get serviced and flushed and fail shortly after, I did a pan drop about 12k miles and used Dex6 on my PERSONAL GTP and its ok at the moment, but it has been serviced regularly too.

If its any conciliation to you, consider I also have a bulletin floating on this forum, ask Bill he's seen it. It states that the M90s can be serviced with Mobil1 5x30 synthetic oil instead of the GM Supercharger fluid. Its old, been revised, still current in its standing by GM, but would you do it to yours??? We've got several threads arguing the pros/cons of possibilities of doing this, nobody has stepped up to it tho, I don't think anyways.

Just food for thought
