I think my 727 is fried. Now I'm at a crossroads...
It's easy to check the pump. Just drop the valve body, remove the front band adjuster,struts and the pump bolts, squirt some WD40 around the perimeter of the pump where it meets the housing, screw two 3/8" bolts into the pump holes made just for that, use an angled pry bar under the heads of said bolt and against the housing, pump popped out, place into vise front down, remove 1/2" bolts from back of pump, stator comes off, remove pump gears noting up/down orientation, use a chisel to knock out front seal, check pump bushing at this time, replace if necessary; remembering to "stake" it. Both front drums probably fell out when you removed the pump; the front band as well...Check the inside of the front of the front drum for scoring in the ring ride area, remove clutches and check condition. Remove clutches from forward drum and check. Post pics of clutches. Stay tuned for reassembly...It's a good idea to first pull the input shaft in and out to see how much end play there is; just to get a rough idea..
