I dont think that MSDS is for the right part number. Nowhere on that sheet does it say any of the correct part numbers. Can you share where you found that? It looks like my previous screenshot was from a 2006 MSDS, below is the newest one I could find.

ACDELCO GM ORIGINAL EQUIPMENT 75W-90 MANUAL TRANSMISSION AND TRANSFER CASE FLUID - 1 QT
GM Part # 88861800
ACDelco Part # 10-4033

Right at the top in small writing it says the correct part number. I have read elsewhere this is made by Petro canada as well.

Viscosity
Viscosity, kinematic : 34.26 cSt (40 °C / 104 °F)
7.7 cSt (100 °C / 212 °F)

If you go to GM's part catalog, there is alot of "manual transmission fluid." I would only use the part number spec'd for this TREMEC unit if you're going with OEM fluid. In my case, I will use Redline D4 and its a valid replacement for GM part #88861800. Viscosity is around 7.5cst but full synthetic.
