How much transmission fluid does a 2008 Chevy Uplander hold?
The transmission fluid capacity for a 2008 Chevy Uplander is about 12 quarts for a full drain-and-fill service. In practice, you should plan for roughly 11–12 quarts, depending on the exact build and whether the torque converter is included in the service.
In most 2008 Uplanders, the vehicle uses GM’s 4T65-E automatic transmission. Total capacity can vary slightly with engine and drivetrain configuration, and whether you perform a complete fluid exchange (pan drop, filter change, and replacement of fluid in the torque converter and cooler lines) or a simpler pan drain and refill. Always verify the level with the dipstick after a warm-up and proper cycling of the transmission.
Capacity details
The figures below reflect common service practices for the 2008 Uplander’s GM 4T65-E automatic transmission. Use these as guidelines and confirm with the dipstick during service.
- Full system capacity (pan drained, new filter, including torque converter and cooler lines): about 11.5–12 quarts (roughly 11–11.5 liters).
- Pan drain and refill capacity (pan drained with filter change, without flushing the torque converter): typically around 4–7 quarts.
Because some fluid remains in the torque converter and lines, always recheck the level after warming up the vehicle and adding fluid gradually to reach the full mark as specified by GM.
Maintenance notes
Fluid type and best practices
Use the Dexron VI specification common to GM transmissions of this era, and avoid mixing brands or types. Follow the vehicle’s owner’s manual or a GM service bulletin for exact fill procedures, including how to check the level with the engine running and the vehicle in Park or Neutral.
In practice, if you’re performing a full fluid exchange, budgeting for about 11.5–12 quarts will cover the pan, filter, and the fluid that sits in the torque converter and cooler lines. For a simple pan drain and refill, expect to replace roughly 4–7 quarts, depending on how much fluid remains in the system after draining.
Summary
For a 2008 Chevy Uplander with the common GM 4T65-E automatic transmission, plan on approximately 11.5–12 quarts for a complete fluid exchange. A pan drain and refill typically involves about 4–7 quarts. Always verify the fluid level with the dipstick after warming the transmission and following the manufacturer’s guidelines.
