What kind of fluid goes in a 2000 Chevy transfer case?
Dexron II or Dexron III automatic transmission fluid (ATF) is the standard fluid for most 2000 Chevy transfer cases. Use the specification listed on your transfer-case tag or in the owner's manual for your exact model to confirm.
In practice, Chevrolet used several transfer-case configurations around 2000. The predominant requirement across those variants is ATF rather than gear oil, with Dexron II or Dexron III typically specified. If your vehicle's manual or a transfer-case tag shows Dexron VI or another specification, follow that guidance, but for many trucks, Dexron II/III ATF remains the safe default.
Common fluid specification for 2000 Chevy transfer cases
The following guidance reflects the typical specification used in GM 4x4 transfer cases from the late 1990s to early 2000s. Always verify with your exact model code and service label.
- Dexron II or Dexron III automatic transmission fluid (ATF) is the standard requirement for most GM 4x4 transfer cases from that period.
Conclusion: For a 2000 Chevy transfer case, ATF Dexron II or Dexron III is the typical fill. If your owner’s manual or transfer-case tag specifies Dexron VI or another fluid, follow that exact recommendation for your model.
How to verify the exact specification for your vehicle
Since Chevrolet used multiple transfer-case options in 2000, you should verify the exact fluid requirement for your truck by checking the transfer case model code and the vehicle documentation.
- Locate the transfer-case model code (for example NP246, NV246, or similar) on the transfer-case housing or in the service manual, and look up the official GM specification for that model.
- Check the owner's manual for the recommended ATF type and the replacement capacity.
- If labels are unclear or unavailable, contact a GM dealer or a qualified mechanic with your VIN to confirm the correct fluid specification for your exact vehicle.
Using the wrong fluid can affect lubrication, cooling, and the engagement of the transfer-case. When replacing fluid, follow the recommended fill level and inspect for leaks after driving.
Maintenance tips and capacity
Typical transfer-case fluid capacity varies by model, but most GM transfer cases hold roughly 2–3 quarts when drained and refilled. Inspect the fluid color and odor; burnt or dark fluid may indicate a service interval is due. Refill to the proper level using the fill plug on the case and clean the area around the plug to prevent contamination.
Bottom line: For a 2000 Chevy transfer case, Dexron II or Dexron III automatic transmission fluid is usually the correct choice, but always verify against your specific transfer-case model code and the vehicle’s documentation.
Summary
In short, the transfer case in many 2000 Chevrolet 4x4 models runs on Dexron II/Dexron III automatic transmission fluid. Confirm the exact specification by checking the transfer-case label or the owner's manual, and consult a GM dealer if you’re uncertain. Using the correct ATF helps ensure proper lubrication, cooling, and reliable 4x4 operation.
