To find the correct amount, you need to:
1. Identify your specific Chevy pickup truck: Year, model (e.g., Silverado 1500, Silverado HD, Colorado, etc.).
2. Determine your transfer case type: This is often a number or code (e.g., NP241, NP261, NP263) found on a tag on the transfer case itself. Your owner's manual might also list it.
3. Consult your owner's manual: This is the most reliable source for the correct capacity.
4. Check a reputable online parts store: Websites like AutoZone, Advance Auto Parts, or Napa Auto Parts allow you to search by vehicle to find the correct transfer case fluid capacity.
Without this information, any answer given would be a guess and could potentially lead to overfilling or underfilling, which can damage your transfer case.
