What type of transmission fluid does the 2007 chevy tahoe use?

The best transmission fluid to use in a 2007 Chevrolet Tahoe is DEXRON®-ViAutomatic Transmission Fluid. You should check the transmission fluid level at least once per month and have the fluid and filter changed every 50,000 miles. The fluid capacity will depend on which transmission in it, the 4L60-E and 4L70-E transmissions can hold 5 quarts and the 4L80-E holdS7.7 quarts. The transmission fluid is vital in prolonging the life of the transmission. If the fluid level becomes low or becomes d***y, it can cause various parts of the transmission to fail. d***y fluid can cause band and gear wear, and even clog the filter, which could destroy the transmission.
