Couple things that might help someone first time:
4R100 fill tube is at a very shallow angle and I found tedious pouring in ATF slowly even with transmission funnel — I bought a larger funnel that a 1/2” latex hose would fit over spout, ran long latex hose down fill tube 10”, suspended funnel from engine hood with vice grips and s- hook (welding rod) towards front of the truck—- think “IV” pole” . Very easy to get to as I had the truck on jack stands. Could dump whole quart in quickly, fluid went in slow due to restriction of funnel spout/ and hose.
As procedure is based on measurements in (qts.) and out (approx. 1-1/2 gallons) I took a 2 gallon pail befor I started, found the line of Point where 1-1/2 gallon would fill. Took a welding rod and bent a loop in the middle and bent the ends down again (forming a big paper clip) that hung on inside of pail. When fluid reached loop - exactly 1-1/2 gallon. After each start/stop pull clip off small 2 gallon pail, dump into larger bucket, rehang clip on pail and ready for next start up, transfer of fluid.
