The 2007 Chevy Avalanche transmission fluid capacity varies depending on the type of transmission and the service being performed. For a standard fluid change, which involves draining the pan and replacing the filter, the capacity is approximately 4 to 5 quarts. However, if you're refilling a completely empty transmission, including the torque converter, the capacity increases to about 11 to 13 quarts.

Transmission Types

The 2007 Chevy Avalanche typically comes with an automatic transmission, specifically the 4L60E or 4L65E model. These transmissions have similar fluid capacities and requirements.

Fluid Change Capacity

When performing a routine transmission fluid and filter change:

  • 4L60E/4L65E: 5.0 quarts

Total Capacity (From Dry)

If refilling a completely dry transmission, including the torque converter:

  • 4L60E/4L65E: 11.2 quarts

Fluid Type

For the 2007 model year, Chevrolet recommends using DEXRON VI automatic transmission fluid. This is an improvement over the DEXRON III used in earlier models, offering better performance and longevity.

Transmission Fluid Change Procedure

1. Warm up the transmission to operating temperature.

2. Locate and remove the transmission pan drain plug.

3. Allow the fluid to drain completely.

4. Remove the transmission pan and replace the filter.

5. Clean the pan and reinstall it with a new gasket.

6. Refill the transmission with approximately 4-5 quarts of DEXRON VI fluid.

7. Start the engine and check for leaks.

8. Check and adjust the fluid level using the dipstick.

Important Notes

  • Always check the owner's manual for the exact specifications for your specific vehicle.
  • Overfilling the transmission can be as harmful as underfilling, so be precise with the fluid level.
  • If you're unsure about performing this maintenance yourself, it's best to consult a professional mechanic.
