How many quarts of transmission fluid does a 2004 Chevy tahoe take
DOT ( 3 ) brake fluid
Master cylinder, located on firewall, driver's side, mounted to the brake booster. A very large circular object about 10" in diameter.
On a 98 Chevy Tahoe, the transmission fluid pressure switch is located on the valve body. It is found to the right of the engine.
If it is only on the outside of the backing plate, it will be the brake line. If it is on the insede it will be the wheel cylinder needing replaced.
