How much transmission fluid does a 2008 Chevy Silverado hold?
Most 2008 Silverados with the common automatic use about 12 to 13 quarts of transmission fluid in total. Heavy‑duty 4L80‑E equipped models can push toward 13 to 14 quarts.
Transmissions used in the 2008 Silverado
The 2008 Silverado lineup primarily relied on two automatic transmissions depending on configuration. The light‑duty 1500 models commonly used the 4L60-E, a four‑speed automatic. The heavy‑duty 2500/3500 (HD) configurations could use the 4L80‑E, another four‑speed unit designed for higher torque. Capacity differs between these two families, and exact numbers can vary with drivetrain, engine, and whether you drain the torque converter during service.
Capacity by transmission type
The figures below reflect typical total fluid capacity for these transmissions in the 2008 Silverado, including fluid still in the torque converter and cooler lines. If you only drain the pan, you’ll typically replace less fluid than the totals shown.
- 4L60-E (common on 2008 Silverado 1500): approximately 12 to 13 quarts (about 11.4 to 12.3 liters) total capacity.
- 4L80-E (HD applications such as 2500/3500): approximately 13 to 14 quarts (about 12.3 to 13.3 liters) total capacity.
These ranges align with GM service literature and common repair guides. Exact capacity can vary by vehicle configuration, production batch, and whether the fluid is drained only from the pan or from the entire system during service. For precise numbers, consult the service manual for your specific VIN and transmission code.
Maintenance and top-up considerations
Use Dexron VI or an equivalent transmission fluid approved by GM. Check the fluid level with the engine at operating temperature and the transmission in Park (or as specified by the manual). When performing a pan‑to‑pan drain and filter replacement, prepare to add a little more fluid to bring the level to the full mark. If you also drain the torque converter or cooler lines, you may need to add additional quarts to reach the proper level.
What affects capacity and service guidance
Transmission fluid capacity is affected by the specific transmission code, the presence of a transmission cooler, and whether you replace the filter during service. Always verify the exact capacity for your truck using the OEM service manual or a dealership diagnostic resource, especially if your Silverado has unusual specifications or aftermarket modifications.
Summary
For a 2008 Silverado, plan on roughly 12–13 quarts of total transmission fluid for the 4L60-E, and about 13–14 quarts if the truck uses the 4L80-E. Always confirm with the owner’s manual or service manual for your exact configuration. Regular checks, proper fluid type (Dexron VI or equivalent), and correct fill procedures help ensure reliable transmission performance.
How many quarts does a 2008 Chevy Silverado 5.3 take?
A 2008 Chevy Silverado 5.3L engine requires 6 quarts of oil when changing the filter. It is recommended to use SAE 5W-30 oil and to initially add about 5 to 5.5 quarts before checking the dipstick to avoid overfilling.
- Oil Capacity: 6 quarts (with filter)
- Oil Type: SAE 5W-30
- Tip for first-time fill: Add 5 to 5.5 quarts first, then check the dipstick and add more as needed.
- Final check: After adding oil, start the engine, let it run briefly, then check the dipstick to ensure the level is correct.
How many quarts of transmission fluid does a 2008 Chevy Silverado take?
A 2008 Chevy Silverado typically takes between 11 and 12.7 quarts of transmission fluid for a total fill, though this can vary significantly depending on the specific transmission model. An initial fill for a transmission like the 4L60-E is around 5 quarts, while a 6-speed transmission may require about 6 quarts to start. Always refer to your owner's manual for the exact capacity of your truck's specific transmission, as using the wrong amount or type of fluid can damage the transmission.
Transmission fluid capacity by model
- 4L60-E: Around 11.2 quarts total fill.
- 6-speed (like the 6L90): Approximately 12.2 to 12.7 quarts total fill, depending on the specific model.
- Other transmissions: Other models, such as the 4L85-E, may have a total fill capacity of up to 13.5 quarts.
Important considerations
- Initial vs. total fill: The amount of fluid needed for a complete drain and fill will be higher than the amount for an initial fill when replacing only the filter.
- Check the owner's manual: This is the most reliable source for your specific vehicle's needs.
- Use the correct fluid: GM recommends Dexron-VI for most automatic transmissions, but verify this in your owner's manual.
