2000 Chev Blazer fluid questions..

[Greaser]

This is a 4.3L powered Chev 4x4...what fluid for front and rear axle,T case?Owner lost her manual and I presume it's just 75W-90 GL5 in the axles and dexron IIE for the T case drain and fill.Can anyone verify this for me.Thanks !

The front and rear diffs use regular GL-5 80W-90 lube. Transfercase depends on the model, BW4401, 4470, and 4472 use Dexron-3 ATF. NV231, and 233 use Dexron-3 ATF. My Book says that models NV136, 236, and 246 use a special GM lube but it doesn't say what the specification is.

Most likely it is a light weight GL-4 gear lube, or maybe even the Sychromesh fluid
I know in the trucks GM starting using synthetic diff fluid, butI'm not sure in the blazer.
