To change all 8-9 quarts the auto tranny system holds, it has to be flushed out via the hose leading to or from the transmission cooler located at the bottom of the radiator. There is no simple drain plug since there is ATF in the transmission, torque conveter, transmission cooler, and the lines leading to/from the cooler.
Make sure to use ATF+4 which is the most heat-resistant ATF suitable for your 32RH transmission. ATF+3 will work too but ATF+4 is a better way to go. Make sure not to use ANY other type of ATF in your auto transmission other than ATF+3 or ATF+4.
