Differentials and transmission fluids changed

[swathdiver]

have a link? part number

Front Differential - 1.51 Quarts - 2 Bottles should do it - 89021671
Rear Differential - 2.15 Quarts - 2 Bottles should do it - 89021677 or 10-4016
Transfer Case - 1.6 Quarts - Dexron VI 10-9395 which is one gallon jug

These are fluids and capacities for 2007-2014 trucks with the NQH transfer case. Mine is a 2009. I was able to reuse my rear differential gasket.

Best deals are ever changing but I bought mine from a GM dealer on ebay and others on Amazon.

Doing this today. Is the 373 rearend open or slip? Aka do i need slip additive?

It is my understanding that all of the NNBS trucks came with positraction G80. Check your RPO sheet in the glovebox. Is yours a 2500 series truck? If you use GM OEM fluid, you do not need positraction additive.

I am going to change the trans fluid in the next week or so and wondered if you changed the shift solenoids when you did the fluid change out?

Did you end up doing it? I am debating the same thing.
