Scratching my head after transfer case fluid change...

[JonnyTahoe]

Curious about what fluid your TC takes, and if it's the same as tranny fluid.

To be clear, I'm wondering if the TC takes transmission fluid (red) or something like AutoTrakII (blue).

I like this Fluid.View attachment 241484

I do, too, since my TC calls for that fluid, but it might not be the right type for the OP's TC.

Your call.

Each are different you really need to check the manual. Mine takes atf and I change it often. I really don’t like autotrac! If my case did call for it I would use it. But I would change it even more often. I am not a fan of autotrac! Some say you can use good synthetic atf I have not experienced so I can not say. There should be a tag on case for model of case .

Is this the first time you changed the fluid on this vehicle?

How much fluid drained out before you started putting new stuff back in?

Yes, first time since I owned it anyway. I would say 1 1/2 came came out now that you mention it. It was beat and dark looking, sure it is way overdue. I don't think I have a trans leak into the Maybe it only holds 1 1/2 instead of 2 like the book says? Dunno.

This is what I used and the book calls for. The Auto Trac II.

whatever you put in it fill it till it starts running out the filler hole. They will hold a gallon but that's not recommended. (only when your tranny seal fails)

Book recommends it because it's the OEM fluid.
