Being curious and the owner's manual being unhelpful, I put in an email to GM asking what fluid my Cruze's M32 6-speed manual transmission takes. It's a valid question considering the nearest GM dealers are 20+ miles away, and I don't routinely go by them.
Here's a paste of the applicable sections of the email:
"Greetings from the Chevrolet Customer Assistance Center! This is a follow-up regarding your inquiry on GM part number 19259104.
I was able to verify that the only thing you need to check on non-GM manual transmission fluids is that is should meet the GM Dexron VI specifications."
So my Cruze takes Dex-VI in its MT. And we've analyzed that fluid 6 ways from yesterday. At least it makes assembly at Lordstown a bit easier to only use 1 fluid no matter what. It also opens up a lot of full-syn options to replace the semi-syn Petro-Canada Dex-VI this spring once the car has more miles on it.
I thought it was interesting, and wanted to share.
