The first major change to the 2010 Avalanche is the transmission. Chevrolet has opted to put a Hydra Matic 6L80 transmission in this model, which does away with the old 4L60 transmission found in previous incarnations. This new addition helps with fuel economy, because instead of having a four speed transmission, you now have a six speed. This addition also helps to reduce the amount of road noise heard by the passengers.
