How many quarts of transmission fluid does a 2008 Chevy Silverado 5.3 take?
About 12 quarts for a full transmission fluid change on a 2008 Silverado 5.3 with the common 4L60-E automatic, roughly 8–9 quarts for a pan drain and refill, and around 14–16 quarts for a full system flush. Exact amounts vary by drivetrain (2WD vs 4WD), whether the filter is replaced, and if a torque converter drain is performed. Verify with the owner's manual or a VIN-specific service bulletin.
Overview of the Silverado’s transmission setup
The 2008 Silverado 5.3 often uses the 4L60-E four-speed automatic transmission. Fluid capacity figures can differ slightly based on whether the vehicle is 2WD or 4WD, the presence of a larger or aftermarket pan, and whether a new filter is installed during a transmission service. The fluid type typically recommended is Dexron VI (or Dexron VI H) per GM specifications, and adhering to the exact capacity for your VIN ensures proper transmission performance and longevity.
Capacity expectations by service method
Before listing the common service scenarios, note that these are approximate figures and depend on the exact vehicle configuration and service approach.
- Drain and fill with pan removal and new filter: about 11–12 quarts total to bring the system back to specification.
- Pan drain and refill without replacing the filter: roughly 8–9 quarts.
- Full system flush (machine-driven): typically 14–16 quarts.
Conclusion for the listed service methods: planning for around a dozen quarts for a full filter-included change, fewer quarts for a simple pan drain and refill, and two dozen mixes when a thorough flush is performed. Always confirm with the service manual for your exact build and consult a professional if unsure.
Practical tips for a safe transmission service
- Use the correct Dexron VI fluid as specified by GM for the 4L60-E in this era of Silverado.
- If replacing the filter, ensure the pan is cleaned and gasket replaced to prevent leaks.
- After any fluid change or flush, run the transmission through all gears with the engine at idle and check the level as per the service manual to ensure proper results.
Summary
For a 2008 Chevy Silverado with a 5.3-liter V8, plan on about 12 quarts for a full fluid change with a new filter, about 8–9 quarts for a simple pan drain and refill, and roughly 14–16 quarts if a complete system flush is performed. Always verify exact capacity for your VIN and use the recommended Dexron VI fluid. Timing and method of service can affect the total amount needed; when in doubt, consult the owner's manual or a qualified technician.
