Transmission fluid and filter change

Amsoil has a nifty reference tool

NOTES: (1) This specification has been updated from Dexron II or III to Dexron VI per a Technical Service Bulletin from the manufacturer
CAPACITIES:
5 quarts Initial Fill
4 speed 4L60-E
Total Fill 11.2 quarts

But make sure you check the levels, fill it until it's correct and remove if you overfill.
 
Speaking of Amsoil, I've been using the older Multi-Vehicle Synthetic Automatic Transmission Fluid. The one in the red package. Has anyone used the newer blue Fuel-Efficient one?
