I think my 727 is fried. Now I'm at a crossroads...
Finished assembling the transmission yesterday. The gap on the throttle valve was pretty wide (~5/16), so I closed it up to just over 1/8".
Transmission is installed, today I'll button up all the loose ends: cooler lines, kick down and shifter linkages, dipstick tube, drive shaft, etc. And since I added new brake lines and rebuilt the rear drums, I'll top off the fluid and bleed them. God I hope I did this right....
