The low sprag overruns In 2nd & 3rd Valve body ? What is that spring & plug that the screen holds in ?

The spring and plug are the throttle pressure limit valve and spring. Most manual shift valve bodies do not apply the rear band in 1st, most "shift kits" do, what do you have for a valve body? If the filter was plugged with clutch material, I suspect that's why you have no high gear, all the high clutch lining is in the filter. You may still have reverse but only because the pressure is higher.
