Cool- blue label all the way. I'm looking right now at an 18, 8 speed currently have 16, 6 speed. Thru all the reding I've done the blue fluid flush and tuning are the remedies. I've looked at the tune files from earlier and later(18) trucks and some tables have been added such as torque converter slip which is where I've been able to produce TC shedder on my 6L80. Great threat, I've learned alot reading it.........

Let Us know what happens....

Doesn't GM have their own fluid, a dexron HP something.......
