727 Time to rebuild

When you take the pump bolts out, you'll find that two of the holes are threaded for 3/8" bolts to use a slide hammer on. I never do use one; rather just insert a couple of bellhousing bolts then use a small crowbar type of L'shaped lever against the inside of the bell. Or gently pry between the front drum lugs against the sun gear shell. First spray some lube around the circumference of the pump. And, of course, the VERY first thing is to yank in and out on the input shaft to check for endplay; just to get a general idea. After that, then remove the pump bolts. Just don't remove the snap ring on the front of the output shaft; save that for your next "rebuild".
