In this video we'll show you how to change out all the dirty transmission fluid in a 2010 GM Chevrolet Suburban (as well as other GM V8 vehicles) in the convenience of your garage. This process is called a transmission flush or fluid exchange when done at a full service auto repair shop. These shops have a machine that hooks into the transmission's ATF supply and return lines in the radiator. My setup system mimics their machines by using a portable oil pump that delivers new fluid into the transmission while the transmission torque converter pumps out the old fluid into in a fluid container.
To perform a complete exchange, I'll be using 12 quarts or 3 gallons of new transmission fluid. The 3 gallons should be enough to ensure that all of the dirty oil has been pushed out of the transmission. I use Valvoline's full synthetic ATF available in one gallon containers at Walmart or other retail auto parts vendors.
I'll start by letting the transmission pump out around 3 quarts of old fluid before pumping in the new fluid into the transmission oil pan. This will reduce the amount of new fluid mixing in with the old fluid.
