This is real easy. Take of the top hose, put a 4' section of 1/2" ID clear tubing on it and run till 2 qts are out. I took a clear 1 gal milk jug and marked the 2 qts. Turn off engine and put 2 qts back in. Repeat till the tranny fluid runs nice and clean red. About 12-14 qts. Might want to buy the clip that goes on the hose where it attached to cooler just in case it's worn or breaks during the procedure. I did just for safety but didn't need it in end. There is no filter to change. Helps to have a helper. My 6 yr olds job was to tell me when it got to 2 qts. on the milk jug. Good luck.
