As I recall the blue fluid is for low-friction versions of the 722.9 which started production in 2010-2011 timeframe. Look for an A89 build code on the build card, this indicates the low-friction version of the 722.9 transmission was installed in the car.

The blue stuff (236.15) is NOT backward compatible for regular friction 722.9's or any 722.6.

The 236.14 red stuff is fully backward compatible for any 722.6.

At least that's how I remember it... maybe someone will correct me.
