The GM 246 transfer case typically holds about 2 quarts of fluid, but it’s crucial to check the specific model for exact capacities. You should use GM AutoTrac II fluid or an equivalent that meets the GM specifications.

That’s great info! I always thought it was around 1.5 quarts. Good to know about the AutoTrac II fluid too!

Just to add, make sure the fluid you choose is compatible with your model year. Some early models had different specifications, so always check your owner’s manual.

What other fluids could be used if I can’t find GM AutoTrac II? Are there modern alternatives that work well?

You know, it’s important to avoid using fluids that don’t meet those specs. They can cause issues down the line. I learned that the hard way!

I feel you! I’ve struggled to find it too. Some people suggest using Dexron III but honestly, I’d stick with the GM approved fluid whenever possible.

I’m curious, how do you know when it’s time to change the fluid? Is there a specific indicator?

Great question! Generally, if you notice grinding noises or if your vehicle hesitates while engaging four-wheel drive, it might be time to check the fluid level and condition.

I’d love to see a demonstration video on how to check fluid levels in the GM 246 transfer case. That would clear up some confusion for me!

I’ve definitely had grinding! Maybe I should schedule a check-up sooner rather than later. Thanks for the tip!

To be honest, I think it’s all about personal preference when it comes to fluids. You’d be surprised at how many people have their own methods!

13

I don’t know about that! I’ve seen way too many people mess up by not following the manual. It’s not just preference.

That’s great info! Has anyone dealt with the process of removing the fill plug? I always find it tricky.

When changing the fluid, having a hand pump makes it a lot easier to refill through the fill plug. I learned that the hard way!

Yes! I used a hand pump last time, and it saved me so much hassle. Good call!
