How many qts of fluid used to drop the pan and chg the filter ?? What fluid should I use ??
Is there any way to get the fluid out of the torque convertor ?

Should be about 7 quarts depending on what trans you have. To flush the whole trans including the torque converter you would need to remove the cooler lines running clean fluid in one and the dirty out the other until it'* all flushed. Use the fluid recommended in the manual.
