For my 02 envoy, I just want to make sure I use the right fluid for all these things.
For the transmission fluid, I'm thinking Valvoline Dex VI, for the differentials, Royal purple 75w-90 gear oil, but what about the transfer case?
And can I also use the same fluids for the 92 c1500 700r4 (obviously it has no transfer case so nevermind that) or should I use regular Dex3/Merc fluid since it's old?
