What type of transmission fluid does the 2009 chevy tahoe use?

The 2009 Chevy Tahoe uses Dexron VI fluid in the transmission. This is a synthetic type of gear oil that is designed to help protect Your gears from excessive wear and tear as well as handle the heat from Your transmission. It is a good idea to check the fluid in Your transmission every time that You change the oil in Your car. You will want to make sure that the fluid levels are full and that it is free from debris. Usually debris will make Your transmission fluid reflective and sparkly because it will have shavings of metal in the fluid. You should also never mix different types of transmission fluid because it can reduce the lubrication capabilities of it.
