Hi again guys,

I own 1998 4door Blazer AWD. I have no switches for 4x4 in the interior if it matters.

My question is:

Which oil can I use in the transmission/transfer case? There is only one sticker saying I have 136 GM transfer case. Weird thing is that it says it have to be filled with DexronII/III - recommended oil is GM Auto-Track II which is not Dexron??? So which one I can use?

Do someone know what type of case do I have exactly - NP-136 or NV-136?

Any help is appreciated... I´m confused...

 

That would be NP 136, found in bravada's and awd astro's/safari's.


You're supposed to use the Auto-Track II Fluid, if it doesn't have Auto-Track in it already, you need to put some in, drive for a bit and then drain it all out and put new stuff back in.

 

Thank you.

 

The atf on that sticker was for coating the bolts, the t-case is made of magnesium and will corrode faster with just a regular steel bolt is put in there.
