The type of transmission fluid the 2003 Chevy Avalanche uses is Dexron VI. The expected cost for a Chevrolet Avalanche 1500 transmission fluid change is between $144 and $165. Labor costs are priced between $89 and $110 while parts are priced at $65. The transmission is one of the most crucial parts of the vehicle. You will come into issues at some point. The gears might become stuck. There may be jerking. Hard shifts could arise and that is not good. You could experience shudders. The transmission might slip. Delayed shifts will cause acceleration issues. If the transmission fluid leaks, that needs to be fixed quickly.

Manual states Dexron III should be used; Dexron VI should be fine, however.
