What type of transmission fluid does the 2005 chevy silverado use?

The type of transmission fluid the 2005 Chevy Silverado uses is Dexron III. The transmission fluid needs to be replaced every 30,000 to 60,000 miles. Along with fluid changes, terrible sounds will come from the transmission. Old transmission fluid will be awful to the ear. A worn out torque converter will cause a headache. The transmission is one of the most critical parts of the vehicle. You will face issues at some point. Hard shifts could arise and that is not good. You could experience shudders. There may be jerking. The gears might become stuck. The transmission could slip. Delayed shifts will cause acceleration problems. If the transmission fluid leaks, that needs to be patched quickly.
