GM 4x4 Transfer Case OIl

John T · Jul 20, 2014

Does anyone have the generic or other brands (Penzoil, Valvoline, Castrol, Quaker State, etc.
etc.) equivalent to

GM Synchromesh Transmission Fluid
GM Part Number 12345349

Used in 4x4 Transfer Cases
NOTE that's NOT the Dexron they use in automatic
trannys in the same vehicle, although its still
called Transmission Fluid

NOT what Billy Bob and Bubba used for years and by golly it "works" Yeah Right, used motor oil would work, lol

Thanks, John T
