Important Considerations:
* Complete vs. Drain and Fill: A complete change involves flushing the entire system, requiring more fluid. A drain and fill only replaces what drains from the pan, which is significantly less. You're likely asking about a drain and fill given the mention of the pan. A drain and fill on this truck will likely use closer to 4-5 quarts.
* Fluid Type: Use only the correct type of automatic transmission fluid specified in your owner's manual. Using the wrong fluid can damage your transmission.
* Condition of the Fluid: If the fluid is very dark, burnt, or smells burnt, a complete flush might be necessary. This would require more fluid.
Recommendation: Consult your owner's manual for the precise amount and type of transmission fluid recommended for your specific vehicle. That's the most reliable source of information.
